When a large number of HTML and MHTML web files are stored on a computer and need to be uniformly archived, sent, or printed, opening them one by one in a browser and saving them as PDF is very time-consuming. This article takes HeSoft Doc Batch Tool as an example to explain how to use the "HTML to PDF" feature in office software to batch import multiple web files, complete the conversion step by step, and obtain PDF files with the same name. It is suitable for scenarios such as data organization, project archiving, and web snapshot preservation.
In daily office work, many documents do not originally exist in PDF form but are saved to computers as web files such as html and mhtml. Examples include web snapshots, report pages exported by systems, offline help documents, email archive pages, and product description pages. Converting a single web file to PDF is not difficult—you can use browser printing or the Save As function. However, if you need to convert dozens or hundreds of html files at once, opening each one, waiting for it to load, selecting print, naming and saving it not only involves a lot of repetitive work but also makes it easy to miss files or save them with the wrong filenames.
This article addresses the problem of "batch converting many HTML web files to PDF." Using office software like HeSoft Doc Batch Tool , you can add multiple web files to a task list at once and then uniformly convert them into PDF documents. The converted files are more suitable for archiving, sharing, printing, and cross-device viewing, and can also reduce compatibility issues caused by web files' dependency on the browser environment.
Applicable Scenarios: When Batch HTML to PDF Conversion is Suitable
HTML to PDF conversion is not just a format change; more importantly, it turns scattered web materials into more stable office documents that are easier to circulate. The following scenarios are particularly suitable for using batch processing:
First, project documentation archiving. Many web pages are saved during a project's lifecycle, such as requirement pages, API descriptions, backend statistical results, and web-based reports. If these continue to be saved in html format, issues like inconsistent styles, missing resources, or changed access paths may arise during later review. After conversion to PDF, the document form becomes more fixed and is suitable for inclusion in project archive directories.
Second, web snapshot preservation. When performing compliance, audit, content evidence retention, or data backup, companies often need to fix the content of a webpage at a specific point in time. Converting html or mhtml to PDF makes the content closer to a "readable document," facilitating later retrieval and submission.
Third, batch printing and sharing. Compared to web files, PDFs are more suitable for printing and are easier to send to others via email, cloud drives, or instant messaging tools. For recipients, opening a PDF is usually more convenient than opening a local html file.
Fourth, reducing repetitive tasks. Manually converting one file might only take a few dozen seconds, but when the number of files increases, the repetitive operation becomes a significant time cost. The purpose of HeSoft Doc Batch Tool is batch processing of office files, making it suitable for centralizing these mechanical steps.
Result Preview: Before Processing, There Are Multiple HTML Web Files
Before processing, you can see multiple web files in the folder, such as 1.mhtml, 2.html, 3.html, 4.html. Their icons typically appear as browser icons, indicating that these files will open in a browser by default. For a small number of files, saving them this way is fine; but if you need uniform delivery, archiving, or printing, it becomes less convenient.

As shown in the screenshot, the files to be processed include both mhtml and html formats. mhtml is typically a web archive format, while html is a common web page document format. During batch conversion, users do not need to differentiate between them individually; simply add the files to the task list as long as they are within the tool's supported scope.
Result Preview: After Processing, PDF Documents with Matching Names Are Generated
After the conversion is complete, the original web files will generate corresponding PDF files, for example, 1.pdf, 2.pdf, 3.pdf, 4.pdf. The filenames maintain a corresponding relationship, making it easy to verify against the original web files and convenient for subsequent unified moving, uploading, or archiving.

The advantage of PDF format lies in its relatively stable layout, unified reading environment, and suitability for printing and circulation. For web materials that need long-term preservation, batch converting HTML to PDF can reduce the risk of display anomalies caused by browser version differences, external resource paths, or missing style files.
Steps: Using Office Software to Batch Convert HTML to PDF
The following uses HeSoft Doc Batch Tool as an example to explain the operation process according to the screenshot sequence. The software interface is categorized by document type and office scenario on the left; the current example uses the "HTML to PDF" function found under "Text Tools."
Step 1: Enter Text Tools and Find the HTML to PDF Feature
After opening HeSoft Doc Batch Tool , select "Text Tools" from the function categories on the left. The main interface will display batch processing functions related to text, web pages, Markdown, and other formats. Based on the screenshot, you can see the "HTML to PDF" card in the function list, indicating that this function is for "Batch convert HTML files to PDF document format."

The purpose of this step is to locate the correct conversion entry among numerous office processing functions. Since the same interface might also include functions like "HTML to TXT," "HTML to Word," and "Markdown to PDF," if the desired output is PDF, you should select "HTML to PDF" to avoid mistakenly choosing conversion related to TXT, Word, or Markdown.
After entering this function, the software will open the corresponding task page. The page top displays the function name "HTML to PDF," which helps the user reconfirm that the current processing type is correct.
Step 2: Add HTML or MHTML Web Files
After entering the "HTML to PDF" page, the upper part of the interface provides "Add File" and "Import Files from Folder" buttons. If the number of files to be converted is small, you can click "Add File" and manually select the html or mhtml files to process; if the files are concentrated in a single folder, it is more suitable to use "Import Files from Folder," which reduces repetitive selection operations.

In the screenshot, 4 records have been added, with the list containing information such as sequence number, name, path, extension, creation time, modification time, and actions. The file names include 1.mhtml, 2.html, 3.html, 4.html, indicating that the software can aggregate the web files to be processed into the same task list. The bottom of the list shows "Record Count: 4"; this step can be used to verify whether all files have been successfully added.
The expected result of this step is: all web files needing conversion appear in the list, and information such as path and extension can be correctly identified. If you find that an extra file has been added, you can use the delete action on the right side of each row to remove it; if there are many files, you can also use the filter and sort buttons in the interface for viewing and verification.
Step 3: Confirm the Task List to Avoid Missing or Incorrect Conversions
Before batch conversion, it is recommended to first check the number and names of files in the list. A common issue for many users when processing large numbers of web files is not conversion failure, but missing some files during import or adding files that do not need conversion to the task. HeSoft Doc Batch Tool displays the name, path, and extension in the list, helping users quickly confirm the file source.
For example, in the screenshot, the 4 files are all located in the same test directory, with extensions being mhtml and html respectively. If your actual directory contains more files, you can first observe by extension whether they are all web files requiring conversion before proceeding to the next step. For office document organization, upfront verification can reduce subsequent rework.
Step 4: Click Next, Set the PDF Save Location
After confirming the task list is correct, click the "Next" button at the bottom of the page. The process indicator at the top shows that this function is divided into three stages: "Select records to process," "Set save location," and "Start processing." The current screenshot is at step 1; clicking "Next" will enter the save location setting stage.
The purpose of this step is to decide where the converted PDF files will be saved. It is recommended to choose a clear output directory based on actual office habits, such as "HTML to PDF Results," "Web PDF Archive," or a project-specific folder. This way, you can quickly find files after processing is complete, and it is also convenient to keep them separate from the original html files to avoid directory confusion.
Although the screenshot does not show the specific details of the save location page, it can be reasonably inferred from the process indicator that the software will require the user to complete the output location setting before starting processing. After setting the save location, you then enter the "Start processing" stage.
Step 5: Start Processing and Check the Conversion Results
After the save location is set, enter the final step "Start processing." At this point, the software will batch convert multiple HTML web files to PDF documents according to the records in the task list. After processing is complete, check the results in your set output directory; you should see PDF files corresponding to the original files.
In this example, 1.pdf, 2.pdf, 3.pdf, and 4.pdf were generated after processing, indicating that all 4 web files were converted. It is recommended to randomly open a few PDFs after conversion to check, confirming that the page content, text, images, and layout meet expectations. This step is especially important if the files are used for formal archiving or external sending.
Frequently Asked Questions and Precautions
1. What is the difference between html and mhtml, and can they both be converted to PDF?
html is a common web file format, which may typically depend on resources like images, CSS, and scripts in the same directory; mhtml is more like a web archive file that encapsulates web content in a single file. The task list in the screenshot includes both mhtml and html, indicating that in the example, both types of web files were added to the "HTML to PDF" task. In actual use, it is recommended to rely on the software's identification results; proceed with conversion for files that can be normally added to the list.
2. What will happen to the PDF file names after conversion?
From the result images, 1.mhtml, 2.html, 3.html, 4.html generated corresponding 1.pdf, 2.pdf, 3.pdf, 4.pdf after conversion. That is, the output files retain the original main file name and change the extension to pdf. This naming method is convenient for verification and also suitable for batch archiving.
3. Why is importing from a folder recommended?
When the number of web files is very large, clicking to add files one by one will still consume time. If the files are already organized in the same directory, using "Import Files from Folder" better aligns with the batch processing approach. It can reduce the number of selections, allowing users to spend time on verification and result checking instead of repetitive clicking.
4. Do I need to keep the original HTML files before conversion?
It is recommended to keep them. PDFs are suitable for reading, archiving, and sharing, but the original html and mhtml files may still have backup value. Particularly when involving project evidence, historical pages, or system-exported data, retaining both the source files and the PDF results can improve data completeness.
5. How to reduce the probability of errors during batch conversion?
It is recommended to organize the source file directory first, ensuring clear file names; check the record count, extensions, and paths after import; set a separate output folder; and spot-check the PDF content after processing is complete. For a particularly large number of files, you can first test the conversion effect with a small sample of files, then batch process all files.
Summary: Reduce Repetitive Labor in Web-to-PDF Conversion with Batch Processing Tools
Batch converting HTML web files to PDF is essentially about organizing scattered, browser-dependent web materials into more stable office documents that are easier to circulate. Compared to manually opening web pages one by one and saving them as PDFs, using HeSoft Doc Batch Tool allows you to import multiple html and mhtml files at once, set a unified save location, and batch generate corresponding PDFs, greatly reducing repetitive operations.
If you frequently need to process web reports, offline pages, web snapshots, or project documentation archives, it is recommended to establish "HTML to PDF" as a fixed office workflow: first organize the source files, then import them in batch, verify the task list, set the output directory, and finally start processing and check the results. This not only improves efficiency but also makes file naming and archive structure more standardized.
