How to batch convert multiple electronic PDFs into scanned versions? A guide to converting to a photocopy style

When you need to uniformly make multiple electronic PDFs into a scanned or photocopied style, you do not have to print, screenshot, or convert pages one by one. This article uses the actual interface of batch office software as an example to explain how to find the "PDF to scanned effect" feature, batch-add individual files or import an entire folder, and choose pure black and pure white, grayscale, color, and different PPI clarity according to the material characteristics. After completing the save location settings, you can start processing all of them at once. The article also provides practical suggestions such as parameter combinations, testing methods, result acceptance, and source file backup.

When archiving company documents, submitting school materials, organizing training resources, or delivering project files, it is often necessary to process electronic PDFs into a style similar to scanned PDFs. The original files may be exported directly from office documents such as Word, docx, doc, PPT, or Excel, with neat text edges and vivid colors that clearly show electronic typesetting characteristics; the target files, however, are expected to resemble the appearance of paper after printing, photocopying, or scanning. For one or two files, manual processing may still be acceptable, but if a folder contains dozens of PDFs, opening each one, exporting images, adjusting black-and-white effects, and recombining them will create a great deal of repetitive work.

HeSoft Doc Batch Tool is an office software designed for multi-file tasks, and its "Convert PDF to scanned effect" feature can accept multiple PDFs at once and convert them using uniform color and clarity settings. This helps keep the same batch of materials consistent in style, while also reducing the chances of missed processing, inconsistent parameters, and file confusion. The following sections explain, from the perspectives of results, workflow, parameter selection, and common issues, how to batch-convert multiple electronic PDFs into scanned versions.

I. Which materials are suitable for converting electronic PDFs to scanned versions

1. PDFs exported directly from office documents

After Word, doc, docx, Excel, xls, xlsx, PowerPoint, or PPTX files are exported to PDF, they usually retain clear fonts, vector lines, and colored elements. If the recipient requires PDFs that resemble scanned copies, you can perform scan-style processing uniformly after the content is finalized, without returning to the original document to modify each page.

2. Materials that need to be unified into a black-and-white photocopy style

Files in the same batch may come from different people, so page colors and layout styles may not be consistent. Using pure black and pure white mode can reduce the color differences between files from different sources, making the overall result closer to uniformly photocopied and scanned materials. This method is suitable for files that focus mainly on body text, tables, and lines, and that do not rely on color to convey information.

3. Grayscale documents that need to preserve shading levels

Some PDFs do not require color, but contain photos, light background shading, charts, or areas with different degrees of darkness. If they are directly converted to pure black and white, some light-colored details may not be obvious enough. In this case, grayscale mode can be used to remove color while retaining a certain degree of light and dark gradation.

4. Multi-page handouts, exam papers, and archival materials

A PDF may contain several or even dozens of pages. If multiple multi-page files need to be processed at the same time, manual screenshotting and reassembly are not only time-consuming but may also cause page order errors. Batch tools execute tasks according to the imported file records, making them more suitable for office scenarios with highly repetitive work and large numbers of files.

II. Comparison of results before and after processing

Before processing: pages have obvious electronic typesetting characteristics

The original PDF in the example has 9 pages. The page background is clean, the blue titles and black body text have smooth edges, and the headers, footers, and text positions are all very regular. This is a typical display effect of a text-based PDF, suitable for online viewing, but it does not look like a scanned file produced after printing and photocopying.

For work that requires later editing, searching, or copying text, the original text-based PDF still has important value. Therefore, even if you need to create a scanned version, it is recommended to keep this original file as a backup.

After processing: pages closely resemble black-and-white scanned or photocopied styles

After conversion is completed, the original colored titles are processed into a black-and-white presentation, and the edges of text and graphics take on an appearance closer to that of paper pages after scanning. The page content, chapter order, and page numbers are still retained, with the changes mainly reflected in color and overall display texture.

From the example, it can be seen intuitively that the processed PDF no longer has a distinct colored electronic document style, but looks more like an image-based scanned file generated from paper materials. Whether to choose this black-and-white effect should depend on the purpose of the file; if colored content carries identifying meaning, then color mode should be selected in the settings.

III. Complete workflow for batch-creating scanned PDFs using office software

Step 1: Open "Convert PDF to scanned effect" in the PDF tool

Launch HeSoft Doc Batch Tool , and click "PDF Tools" in the left navigation bar. The main area will list different PDF processing items. Find item number 27, "Convert PDF to scanned effect", and click to enter.

In the screenshot, the description of this feature is to batch-convert PDF pages into image effects similar to paper scanned copies. Note that it should not be confused with "Convert PDF pages to image format" or "Convert color PDF to black and white". The goal of this article is not simply to change colors or export images separately, but to produce a PDF result with a scanned appearance through a dedicated process.

After entering the feature, the top will show four processing stages: select the records to process, set processing options, set the save location, and start processing. Operating in order can reduce the chance of missing settings.

Step 2: Add multiple PDFs or import an entire folder

In the first stage, you can click "Add Files" to select the PDFs to convert. If the target files are centrally stored in the same directory, you can also use "Import files from folder" to load the relevant files in that folder at once. This method is especially suitable for batch tasks that have been organized in advance by project, date, or material type.

After files are imported, the software will display information such as name, path, extension, creation time, and modification time in the list. In the example list, there are four files: 1.pdf, 2.pdf, 3.pdf, and 4.pdf, and the bottom summary shows "Record count: 4". Users can check the imported quantity based on this.

If a file that does not need to be converted is mixed into the list, you can click the delete icon in that row's action column. If you need to reselect everything, you can use "Clear" at the top. Before clicking "Next", it is recommended to check the file names, paths, and total record count in order, and especially confirm that files from a previous task have not been mistakenly added to the current batch.

Step 3: Choose a color mode based on the document content

After entering the "Set processing options" page, you can see that color mode is a required item, and the interface provides three modes: pure black and pure white, color, and grayscale. In the screenshot, the example selects "Pure black and pure white".

Pure black and pure white is suitable for creating an ordinary photocopy style, especially for files whose main content consists of body text, tables, questions, and line drawings. It can unify colored titles in the original PDF into black and white, making multiple documents look more consistent. However, if the pages contain light-colored text, complex photos, or data distinguished by color, you should test first to avoid important information becoming unclear after black-and-white conversion.

Grayscale mode does not retain color, but can represent different levels from light to dark. For files with photos, shadows, light backgrounds, or gradient charts, grayscale is usually safer than pure black and white. Color mode is suitable for scenarios where colored markings, chart categories, seals, or other color information must be retained.

Step 4: Set clarity to 96, 150, 200, or 300 PPI

Below the color mode is the image clarity setting, which provides Basic (96 PPI), Normal (150 PPI), Clear (200 PPI), HD (300 PPI), and Custom. The example selects "Clear (200 PPI)". For most text-based PDFs, 200 PPI can serve as a reference setting for initial testing.

96 PPI is more suitable for quick preview and may not be appropriate for materials with small fonts and thin lines. 150 PPI is suitable for ordinary screen reading or internal circulation. 200 PPI can balance general text legibility and batch processing efficiency. 300 PPI is more suitable for small text, dense tables, and pages that need to be enlarged for viewing. Custom can be used for tasks where the recipient has specified a clear resolution standard.

When choosing clarity, you should not simply pursue the highest value. When there are many files or each file has many pages, higher PPI will increase processing workload and may consume more storage space. The correct approach is to select one representative PDF for testing first: ideally it should include body text, small fonts, tables, and images at the same time. After confirming that the results meet the requirements, apply the same settings to all files.

Step 5: Confirm options and proceed to save location settings

After completing the color mode and clarity settings, click "Next" at the bottom to enter "Set save location" as shown in the top workflow. If the parameters are incorrectly selected, you can return and modify them using "Previous".

The save directory should be kept separate from the original file directory as much as possible. For example, you can create two subfolders under the project folder: "Source PDFs" and "Scanned PDFs". This preserves the original versions that can still be searched and copied, while also making it easy to quickly find the final files for submission. If there are many batches, you can also add a date or purpose to the output directory name to prevent confusion between different batches.

Step 6: Start processing and complete batch result acceptance

After the save location is confirmed, proceed to the "Start processing" stage according to the workflow. The software will execute each item based on the file list and generate results using the same set of color and PPI parameters. During batch processing, do not delete, move, or rename source files, as this may cause path changes.

Completion of processing does not mean the task is finished. It is recommended to open the output directory and first check whether the number of files matches the imported record count, then spot-check different types of PDFs separately. For multi-page files, check the first page, middle pages, and last page; for files with complex content, zoom in to check table lines, small fonts, light-colored areas, and image details. Also confirm page order, page orientation, and whether the body text is complete.

IV. Suggested parameter selection for different scanned-version requirements

Option 1: Ordinary black-and-white text materials

If the PDF consists mainly of black body text, titles, and simple tables, you can start with "Pure black and pure white + 200 PPI". This combination is suitable for common materials such as handouts, notices, practice questions, and duplicate copies of text archives, with output close to ordinary black-and-white photocopies.

Option 2: Contracts with small fonts or dense tables

If the page font is small and the table lines are thin, consider using "Pure black and pure white + 300 PPI" or "Grayscale + 300 PPI". The specific color mode to choose depends on whether there are light-colored lines and background shading in the source file. If detail loss occurs after pure black-and-white testing, switch to grayscale.

Option 3: Non-color materials with photos or graphics

When a PDF contains photos, diagrams, shadows, or gradients, but the submitted result does not require color, you can choose "Grayscale + 200 PPI". If there are many image details or enlarged viewing is needed, increase to 300 PPI.

Option 4: Files that must retain color information

If colors such as red, blue, and green themselves represent different categories, or if the file contains markings that must be identified in color, color mode should be selected. Clarity can start from 200 PPI for testing. Do not remove colors with business meaning just to pursue a black-and-white photocopy style.

V. Why batch processing is more efficient than manual file-by-file conversion

Manual processing usually requires repeatedly opening PDFs, exporting pages, adjusting colors, setting resolution, recombining them, and saving files. As the number of files increases, the number of operations grows exponentially, and different files may end up using different parameters because of temporary adjustments, resulting in inconsistent final styles.

Batch office software centralizes these repetitive actions into one task. Users only need to build a file list once, set the color and clarity once, and specify the save location once, and then multiple PDFs can be processed. This method is especially suitable for work with clear standards and similar file structures, such as multiple forms from the same project, multiple sets of handouts from the same course, or archival materials from the same batch.

In addition, the import list displays the record count and file paths, making it easier to check before starting; a unified output directory also makes it convenient to inspect after completion. The value of batch processing is not to skip quality checks, but to reduce mechanical operations and leave time for parameter confirmation and result acceptance.

VI. Common issues and operational precautions

1. Do the original PDFs need to be backed up in advance?

It is recommended to always keep the original text-based PDF. Files that have been processed into a scanned style are mainly used to meet specific submission or display requirements, while the original files are still useful for searching, copying text, later editing, and regenerating other versions. Storing source files and output files in separate directories is a safer practice.

2. Why should the record count be checked after batch import?

Although importing from a folder is convenient, users still need to confirm that all target files are in the current list. The record count at the bottom of the list can serve as a first-level check. If 20 files are expected to be processed, but the interface only shows 19 records, first check the source directory and import scope before continuing.

3. What should be done if some light-colored content is not obvious after black-and-white processing?

This is usually related to the source file's light colors or the pure black-and-white conversion. You can return to the settings page and try grayscale mode to retain more light and dark gradation. If the content itself must rely on color recognition, color mode should be used.

4. How to choose between 200 PPI and 300 PPI?

For ordinary body text and regular tables, test 200 PPI first; for small fonts, thin lines, complex images, or files that need to be enlarged, try 300 PPI. Do not judge solely by the parameter; the actual readability of the processed result should be the main criterion. For large batch tasks, testing first and then converting uniformly can avoid rework.

5. Is a scanned-version PDF the same as actually scanning with a scanner?

This feature processes PDF pages into an image effect similar to paper scanned copies, with the focus on how the pages are presented. It can meet many document organization scenarios that require a scanned appearance, but if a business requirement explicitly requires scanning the physical original, you should still follow the other party's rules and not treat visual effect conversion as equivalent to scanning the actual paper original.

6. What should be checked before formal submission?

At least check the number of output files, file names, total page count, page order, color mode, text readability, and image details. For important materials such as contracts and forms, also confirm page by page that signatures, seals, numbers, and key fields have not become difficult to identify due to color conversion.

VII. Summary

To uniformly convert multiple electronic PDFs into scanned versions, there is no need to print, screenshot, or manually convert them to images one by one. Using the "Convert PDF to scanned effect" feature in HeSoft Doc Batch Tool , you can centrally import PDF files or an entire folder, choose pure black and pure white, grayscale, or color mode according to the purpose, configure 96, 150, 200, 300 PPI, or custom clarity, then set the output location and start batch processing.

In actual operation, it is recommended to first run a trial with one representative file: ordinary black-and-white text materials can start with pure black and pure white at 200 PPI; materials with light-colored graphics or photos can be tested in grayscale; files that need to retain color information should use color mode. After confirming the results, process the entire folder, and finally check the file count, page count, and key content. Following this workflow can reduce a large amount of repetitive work while ensuring usable results, and complete the creation of scanned-style and photocopy-style PDFs more efficiently.
