This article explains how to use HeSoft Doc Batch Tool to batch convert multiple web page files with different extensions into a unified HTML format. Regardless of whether the original files are .mhtml, .htm, or .html, they can all be imported at once through a batch processing workflow in the office software, set the save location, and execute the conversion, thereby reducing repetitive operations caused by saving files individually. It is suitable for scenarios such as data archiving, organizing web page materials, and standardizing system-exported files.
In daily office work, material organization, web archiving, or system data exports, it is common to encounter the problem of inconsistent file extensions across a batch of web page files. For example, some files are .mhtml, some are .htm, and others are .html. Although these files are all related to web content, inconsistent formats add considerable extra communication and manual correction costs during subsequent uploading, archiving, system import, or when handing them over to others.
If there are only one or two files, manually opening and saving them as HTML might be acceptable; however, when the number of files increases to dozens or hundreds, processing them one by one is not only time-consuming but also prone to missed conversions, renaming errors, and disorganized save paths. This article aims to solve: How to batch convert HTML web files of various formats into a uniform .html format using office software.
Below, using HeSoft Doc Batch Tool from the screenshot as an example, it demonstrates the complete workflow from selecting the function and importing files to completing the batch conversion. Its positioning is as a document and file batch processing office software, suitable for reducing repetitive work and improving file organization efficiency.
Applicable Scenarios: When is batch conversion of HTML web files needed?
Batch converting web page files such as mhtml, htm, and html into a uniform html format is common in the following office scenarios.
First, web page material archiving. Many people export web page materials from browsers, business systems, or knowledge bases, and the exported file extensions may not be entirely consistent. Unifying them as .html makes it more convenient to categorize and save them by project, date, or client.
Second, format standardization before system import. Some content management systems, internal knowledge platforms, or material libraries only accept .html files. If a folder contains a mix of .mhtml, .htm, and other formats, they need to be batch converted before uploading.
Third, cross-departmental collaboration. In multi-person collaboration, unified file formats can reduce communication costs. The recipient does not need to determine how to open each file and can more easily write subsequent processing rules.
Fourth, organizing historical files. Web page files saved in the past may come from different sources and have different extensions. Through batch conversion, historical web page files can be organized into a unified format, facilitating long-term preservation and retrieval.
Therefore, this type of operation is not just about "changing the extension," but about making web files more standardized, stable, and manageable in batches within office workflows.
Effect Preview: Mismatched file formats before processing, all HTML after
Let's first look at the file status before processing. In the screenshot, you can see that there are 4 web page files in the same folder, with extensions including .mhtml, .htm, and .html. Although all of them can be recognized by a browser, the file format identifiers are not uniform.
This state is very common during manual organization: the file icons look similar, but the actual extensions are different. If a unified delivery, upload, or archiving is needed later, they must be converted into the same HTML file format.
After processing is complete, the 4 files in the screenshot have all been changed to the .html extension. That means the original 1.mhtml, 2.htm, 3.htm, and 4.html were uniformly processed into 1.html, 2.html, 3.html, and 4.html.
From the results, it can be seen that the file naming after batch conversion is more consistent, and the extensions are uniformly HTML. This is more convenient for subsequent file distribution, compressed packaging, system import, or long-term material preservation.
Operation Steps: Batch Converting Web Page Files to HTML Using Office Software
The specific operations are explained below following the order of the screenshots. The entire process adopts a wizard-style processing method: first select the function, then add the files to be processed, and then configure and execute the conversion step-by-step.
Step 1: Enter Text Tools and select the "HTML to HTML" function
After opening HeSoft Doc Batch Tool , you can see different tool categories on the left side, including Word tools, Excel tools, PDF tools, Text tools, etc. Since the processing objects this time are web and text-type files, you need to enter the Text tools category on the left.
In the function list, find and click "HTML to HTML". In the screenshot, this function is located in the Text tools area, and the interface indicates its purpose is to "Batch convert HTML files to HTML file format."
The purpose of this step is to enter the correct batch conversion function. After selecting this function, the software will enter a dedicated HTML-to-HTML processing interface for importing web page files and completing the uniform format conversion.
Step 2: Add the web page files to be processed
After entering the "HTML to HTML" function, the top of the interface provides buttons such as "Add File", "Import Files from Folder", "Clear", and "More". According to the screenshot, this is currently Step 1: Select the records to be processed.
If the number of files to be converted is small, you can click Add File and select the mhtml, htm, and html files one by one. If the files are all in the same folder, it is more recommended to use Import Files from Folder, which can add the files from the target folder to the processing list at once.
From the list in the screenshot, you can see that the software has identified and listed 4 records, including information such as file name, path, extension, creation time, and modification time. The extension column shows different types such as mhtml, htm, and html, indicating that these files have been successfully imported into the batch processing list.
The expected result of this step is: all web page files to be converted appear in the list, and the record count matches the actual number of files to be processed. The bottom of the screenshot shows "Record count: 4," indicating that 4 files will be processed.
Step 3: Verify the file list and remove unnecessary records if needed
After importing the files, it's not advisable to proceed to the next step immediately; instead, the list should be checked first. Focus on three key items: whether the file names are correct, whether the paths point to the target folder, and whether the extensions are the web file types intended for this processing.
In the "Actions" column on the right side of the list, you can see a delete icon. If a file that does not need conversion was added by mistake, you can use this action to remove it from the processing list. There is also a Clear button at the top, suitable for re-selecting files in case of an import error.
The purpose of this step is to avoid converting irrelevant files together, thus reducing rework. For batch processing software, verifying the list before processing is crucial, as it determines which files the subsequent conversion actions will target.
Step 4: Click "Next" and set the save location
After confirming the list is correct, click Next at the bottom of the interface. As seen in the workflow bar from the screenshot, the software's processing flow includes: selecting records to process, setting the save location, and starting processing. Therefore, clicking Next will lead to the save location setting step.
The purpose of setting the save location is to determine where the converted HTML files will be output. To facilitate result verification, it is recommended to set the output location to a new folder, such as "HTML Conversion Results" or "Unified Web File Formats." This avoids mixing them with the original files and makes comparison checks easier after the conversion is complete.
If you need to preserve the original files, it is advisable not to overwrite the original file directory directly; instead, choose a separate output directory. This is a prudent practice in batch file processing.
Step 5: Start processing and check the conversion results
After the save location setting is complete, continue following the software wizard to the Start Processing stage. The software will batch convert the imported web page files and save the results to the specified location.
After processing is complete, open the output folder to check. According to the effect image, the extensions of the converted files have been unified to .html. For example, the original 1.mhtml was converted to 1.html, 2.htm and 3.htm were also converted to 2.html and 3.html, and files that were originally html remain as unified html results.
The expected result of this step is: HTML files corresponding to the original files appear in the output directory, all extensions are .html, and the file count matches the processing list.
Common Questions and Precautions
1. What is the difference between mhtml, htm, and html? They are all related to web page files, but their saving methods and extensions differ. mhtml is commonly used for saving single-file web page archives, while htm and html are common web page file extensions. Unifying them as html makes it easier for subsequent system recognition and file management.
2. Does batch conversion simply mean modifying the extension? From the operation flow, the software provides the "HTML to HTML" function and completes it through the process of importing files, setting the save location, and starting processing. In actual office work, it is not recommended to rely solely on manually changing the extension to process web page files, as this may lead to inconsistencies in content or encoding.
3. Is a backup needed before conversion? It is recommended to keep the original files, especially for web archive files like mhtml. During batch processing, it is best to output the results to a new folder, so that even if reprocessing is required, you can fall back to the original files.
4. When there are many files, should I choose "Add File" or "Import Files from Folder"? If the files are concentrated in one directory, prioritize using "Import Files from Folder"; if only a few scattered files are to be processed, "Add File" can be used. This reduces the time spent on repetitive file selection.
5. How to confirm if the conversion was successful? Check from two aspects: first, whether the number of output files matches the number of imported records; second, whether all file extensions have become .html. You can also randomly open a few files to confirm that the web content displays normally.
Summary: Using batch processing tools to unify web file formats reduces repetitive office operations
Batch converting web page files such as mhtml, htm, and html into a unified HTML format is a very practical step before material organization, web archiving, and system import. Compared to manually opening, saving as, or modifying file names one by one, using office software like HeSoft Doc Batch Tool allows you to import multiple files at once, complete the save location setting and batch processing following a wizard, greatly reducing repetitive labor.
If your folder also contains a mix of .mhtml, .htm, .html, and other web page files, it is recommended to follow the steps in this article: enter Text Tools, select "HTML to HTML," import files, verify the list, set the save location, and start processing. This allows you to obtain unified .html file results faster, making subsequent archiving, uploading, and collaboration more efficient.
