How to batch convert text-based PDFs into photocopied scanned effects? A tutorial on creating a black-and-white scanning style

Many contracts, lecture notes, data compilations, and archived documents are originally clear text-based PDFs, but when submitting, printing, or simulating paper photocopies, they need to be uniformly processed into a scanned-document style. This article explains how to use HeSoft Doc Batch Tool to import multiple PDF files at once, choose pure black and pure white, color, or grayscale modes, and set image clarity such as 96, 150, 200, or 300 PPI, to batch-generate PDFs that resemble photocopied scans and reduce the workload of converting files one by one and repeating settings.

In daily office work, we often encounter this situation: we have dozens or even hundreds of text-based PDFs exported from Word, docx, doc, or other electronic documents. The pages are very clear and the font edges are smooth, but business submission, document archiving, print testing, or layout demonstrations require the files to present a visual effect similar to paper documents that have been photocopied or scanned. If you open each PDF one by one, then capture each page as an image and recombine them, the steps are not only cumbersome but also prone to problems such as missing pages, inconsistent clarity, and disorganized output files.

What this article addresses is the problem of batch converting many text-based PDFs into a photocopied or scanned appearance. Using the "PDF to Scanned Effect" feature in the office software " HeSoft Doc Batch Tool ", you can add multiple PDFs at once, uniformly select the color mode and image clarity, and then set the save location and start processing. For administrative, teaching, archival, and printing scenarios with many repetitive file operations, this batch processing method can significantly reduce mechanical work.

1. Which scenarios are suitable for converting text-based PDFs into a scanned effect

Converting a PDF to a scanned effect is not simply renaming the file, but rather making originally clear and neat electronic pages present a visual impression closer to paper materials that have been scanned or photocopied. The following scenarios are usually more suitable for this processing method.

1. Contracts, application materials, and internal circulation documents

Some materials need to be circulated in a form close to printed and then scanned copies. The source files may be Word, doc, docx, or text-based PDFs exported from layout software. If a unified visual form is needed, multiple PDFs can be batch processed into a scanned effect, avoiding separate printing and scanning for each file.

2. Course handouts, exam papers, and learning materials

Teachers or academic administrators often need to process a batch of electronic handouts, class notes, exercises, and exam papers. Converting clear electronic PDFs into a black-and-white photocopy effect can be used for print preview, copy quality simulation, or paper material display.

3. Archive organization and printing tests

Archivists may need to keep the same batch of PDFs consistent in color mode and clarity; printing staff may need to compare page effects under different parameters such as 96 PPI, 150 PPI, 200 PPI, or 300 PPI. Batch tools can apply unified parameters to all files to be processed, reducing the probability of inconsistent manual settings.

4. Many files need unified processing

When there is only one file to process, manual operation is still acceptable; when the number of files increases to dozens, converting them one by one will take a lot of time. HeSoft Doc Batch Tool is positioned for office file batch processing and can organize importing, parameter setting, saving, and processing into a continuous workflow, making it more suitable for multi-file tasks.

2. Effect preview: differences between text-based PDF pages before and after processing

Before processing: standard text-based PDF page

Below is the PDF before processing. It can be seen that the page background is relatively clean, and the title, body text, and blue subtitles have clear edges, presenting a typical electronic document export effect. The page content is neatly arranged, and color reproduction is also relatively clear.

This kind of PDF is suitable for screen reading and regular printing, but if the business requires a black-and-white photocopy, paper scan, or image-based page visual form, the original effect may not meet the requirements.

After processing: black-and-white photocopied scanned effect

After processing, the page is converted to a black-and-white visual style. The title area changes from the original dark blue-gray background to a more obvious solid black effect, and the blue subtitles are also presented in black. The text and lines now have an image appearance closer to that of printed, photocopied, and then scanned pages.

From the before-and-after comparison, it can be seen that the focus of this function is to uniformly change the presentation of PDF pages, rather than modifying the body content. The example uses the "Pure black and pure white" color mode and "Clear (200 PPI)" image clarity, so the output pages retain the main text structure while forming a relatively obvious black-and-white photocopy style.

3. Steps for batch converting PDFs to a scanned effect

Step 1: Enter the PDF tools and select the corresponding function

Open HeSoft Doc Batch Tool , and in the function category on the left, select "PDF Tools". After entering the PDF tools list, find item number 27, "PDF to Scanned Effect". The function description in the interface says it batch converts PDF pages into an image effect similar to paper scanned copies. Click the function card to enter the processing page.

Purpose of this step: Enter the dedicated PDF scanned effect processing workflow, rather than selecting other functions such as "Convert PDF pages to image format" or "Convert color PDF to black and white". Although these function names are similar, their processing goals are not exactly the same. When selecting, "PDF to Scanned Effect" should be used as the standard.

Expected result: The software opens a step-by-step operation interface, in which the workflow includes selecting the records to process, setting processing options, setting the save location, and starting processing.

Step 2: Add multiple text-based PDFs at once

On the "Select records to process" page, you can use the "Add Files" button at the top to import one or more PDFs. If the files to be processed are already stored together in the same folder, you can also use "Import files from folder" to reduce repeated file selection operations.

After the files are imported, the list displays information such as serial number, name, path, extension, creation time, and modification time. In the screenshot, 1.pdf, 2.pdf, 3.pdf, and 4.pdf have been added at once, for a total of 4 records, which shows that this function supports batch processing of multiple PDFs in the same task. If a file is accidentally added to the list, it can be removed using the delete icon in the corresponding "Actions" column; if you need to reselect the entire batch of files, you can use "Clear" at the top. After confirming the list, click "Next" at the bottom.

Purpose of this step: Establish the file list for this batch processing task, confirm that all PDFs to be converted have been added, and exclude irrelevant or duplicate files.

Expected result: The bottom of the page displays the correct record count, and the file names and paths match the actual task. For a large number of files, it is recommended to focus on checking the first and last files as well as the total quantity.

Step 3: Select the scanned document color mode

After entering "Set processing options", first set the required "Color mode". The screenshot provides three choices: "Pure black and pure white", "Color", and "Grayscale".

• Pure black and pure white: Suitable for simulating ordinary black-and-white photocopies, text archives, and black-and-white handouts. The example effect uses this mode.
• Color: Suitable for files that need to preserve color titles, charts, seals, or other color information from the original pages, while presenting a scanned image style.
• Grayscale: Suitable for materials where you want to preserve light and dark gradations but do not need color information. Compared with pure black and pure white, grayscale is usually better at representing shadows, light backgrounds, or photo details.

Purpose of this step: Unify the page color effect of the entire batch of PDFs and avoid different files using different conversion standards.

Expected result: The radio marker in front of the selected mode is in the selected state. If the goal is to produce a photocopy scan effect consistent with the example in this article, you can select "Pure black and pure white".

Step 4: Set image clarity

The same page also provides the "Image clarity" setting, including "Basic (96 PPI)", "Normal (150 PPI)", "Clear (200 PPI)", "HD (300 PPI)", and "Custom". In the screenshot, "Clear (200 PPI)" is selected.

Higher clarity is not necessarily suitable for all tasks. The higher the PPI, the better it generally is for preserving small text and page details, but processing time and output file size may also increase accordingly. You can choose based on the intended use: for ordinary screen preview, you can first test 96 or 150 PPI; for office materials with dense text that need balanced clarity, you can choose 200 PPI; for pages with high detail requirements or planned for printing, you can test 300 PPI. The custom option is suitable for tasks with already clear delivery standards, but actual needs should remain the main consideration.

Purpose of this step: Strike a balance among page readability, processing efficiency, and output size.

Expected result: All imported PDFs will generate the scanned effect at the same clarity. When processing important materials for the first time, you can first test with a small number of samples and then determine the parameters for the entire batch.

Step 5: Set the save location and start processing

After completing the color mode and image clarity settings, click "Next" to enter "Set save location". Choose a suitable output directory according to the current task. It is recommended to save the results in a separate new folder and not mix them with the original PDFs. After confirming the save location, continue to "Start processing" and follow the interface prompts to start the batch conversion.

Purpose of this step: Specify the storage location of the processed files and execute the batch task that has already been configured.

Expected result: The software processes the PDFs one by one according to the file list, without requiring the user to repeatedly open each file and set the color and clarity again. After completion, you can go to the selected output location to check the generated results.

4. How to check the results after processing is complete

After the batch task is finished, it is not recommended to confirm only whether the files have been generated; sampling checks should also be performed. First, check whether the number of output files matches the number of imported records; second, open one of the PDFs and view the first page, middle pages, and last page to confirm that the page count, orientation, and content are normal; finally, zoom in to view small text, table lines, and footers to determine whether the current PPI meets reading or printing requirements.

If the entire batch of files comes from the same source and has a consistent layout, checking a few of them can usually quickly reveal parameter problems; if the files come from complex sources and include color charts, light-colored text, or photos, you should select different types of files for checking. If you find that the black-and-white mode has caused important light-colored content to be lost, you can switch to grayscale or color mode and process again.

5. Common questions and precautions

1. How should I choose between pure black and pure white and grayscale?

When the content is mainly text and you want an obvious black-and-white photocopy style, you can preferentially choose pure black and pure white. When the pages contain shadows, photos, light backgrounds, or graphics with many gradations, grayscale is usually more suitable. When color logos, charts, or seal colors must be preserved, you should choose color.

2. Why is it not recommended to directly choose 300 PPI for all files?

300 PPI is suitable for tasks with high detail requirements, but when there are many batch files, higher clarity may lead to larger output size and longer processing time. In office scenarios, you can first process one sample at 200 PPI, confirm the effect, and then decide whether to increase the parameter.

3. Do I need to back up the original PDFs before conversion?

It is recommended to keep the original files and save the output results to a new folder. The scanned effect is suitable for display, submission, or print simulation, but the original text-based PDFs are usually more convenient for retrieval, copying, and subsequent editing. The actual structure of different files may vary, and whether the converted files can still search text should also be determined based on the generated results.

4. Why should I still check the record count after batch importing?

Although importing from a folder is more efficient, the folder may contain PDFs that do not need to be processed, or some files may be stored in other directories. Checking the total record count, file names, and paths can help detect missed or incorrectly selected files before processing begins and avoid rework after the entire batch task is completed.

5. What should be noted when handling sensitive files?

Contracts, personnel materials, and internal archives may contain sensitive information. Before processing, you should operate according to your organization's data management requirements, properly select input and output directories, and confirm the file content and save location before delivery.

6. Summary

The key to making a large number of text-based PDFs look like photocopied or scanned copies is not complex single-file techniques, but whether multi-file processing can be completed uniformly and efficiently. HeSoft Doc Batch Tool , as batch processing software oriented to office scenarios, can import multiple PDFs at once, uniformly set pure black and pure white, color, or grayscale modes, and execute tasks at 96, 150, 200, or 300 PPI or custom clarity, thereby reducing the repetitive labor of opening files one by one, repeatedly configuring settings, and manually saving.

In actual operation, it is recommended to first select one or two representative PDFs for testing. If you need the black-and-white photocopy scan effect shown in this article, you can first select "Pure black and pure white" and "Clear (200 PPI)", check text readability and output size, and then import the complete folder for batch processing. This can ensure the effect and also improve PDF organization efficiency more reliably.
