When a folder contains multiple video formats such as MKV, AVI, MOV, and WEBM, converting them one by one is not only time-consuming but also prone to missing files. Using HeSoft Doc Batch Tool as an example, this article demonstrates how to use video tools in office software to batch convert multiple video files to the MP4 format, and illustrates the conversion results with before-and-after screenshots to help users quickly unify video formats, reduce repetitive operations, and improve file organization and material delivery efficiency.
In daily office work, course creation, material archiving, short video clip delivery, or project data organization, a very practical problem often arises: a single folder contains video files in different formats such as MKV, AVI, MOV, and WEBM. Some players, conference systems, web backend systems, or mobile devices have inconsistent format support, meaning some videos can be played, some require additional codec installations, and others are unrecognizable after uploading. Compared to opening conversion software and selecting the output format for each file individually, batch converting many video files to the MP4 format is clearly more suitable for office scenarios.
This article will combine screenshots to introduce how to use the HeSoft Doc Batch Tool office software to uniformly batch convert multiple videos in different formats to MP4. Its core value is not single-file processing but batch processing for a large number of files: import once, convert in a batch, and output uniformly, reducing repetitive clicks and manual verification time. After reading this article, you can clearly understand what problems this function is suitable for solving, what changes occur before and after processing, and the specific steps to follow.
Applicable Scenarios: When do you need to batch convert videos to MP4
MP4 is currently one of the common video formats with good compatibility, with a high recognition rate on Windows, macOS, mobile phones, tablets, web players, common editing software, and many content management systems. Therefore, when you need to hand over video materials to colleagues, upload them to a platform, archive them in a database, or provide a unified preview to clients, batch converting formats like MKV, AVI, MOV, and WEBM to MP4 can often reduce compatibility issues during playback and transmission.
This function is particularly suitable for the following types of office scenarios. First, marketing, operations, or training teams need to organize a batch of video materials from different sources with non-uniform formats, which can easily lead to errors during subsequent uploading or playback. Second, administrative, teaching, or project management personnel need to organize meeting recordings, course recordings, and on-site shooting videos into a unified format for easy long-term archiving. Third, in editing and design collaboration, raw materials may come from cameras, mobile phones, screen recording software, or download platforms with different extensions; unifying them as MP4 makes distribution and preview easier. Fourth, internal company databases require standardized file formats to avoid difficulties in opening files years later due to obscure formats.
If there are only one or two files, manual conversion might be acceptable; but when the number of files reaches dozens or hundreds, manual individual processing is very inefficient. The value of batch video to MP4 conversion lies in handing over repetitive file conversion work to the office software, allowing users to spend their time on content review, data classification, and delivery confirmation.
Effect Preview: Before processing, there are multiple video formats; after processing, they are unified as MP4
From the pre-processing folder, you can see that the same batch of video files contains multiple extensions. For example, Bus.mkv and Car.mkv are MKV files, City_Night.avi, Running.avi, and Traffic.avi are AVI files, Overpass.mov, Stream.mov, and Surfing.mov are MOV files, and Park.webm is a WEBM file. Such folders are common in real office work: the file names look neat, but the formats are scattered, leading to inconsistencies during subsequent playback, upload, or delivery.
After the batch conversion is complete, you can see that the video files with different original extensions have been uniformly converted to MP4 files, such as Bus.mp4, Car.mp4, City_Night.mp4, Overpass.mp4, Park.mp4, Running.mp4, Stream.mp4, Surfing.mp4, and Traffic.mp4. The file type column also shows as MP4 File, indicating that this batch of videos has been output according to the same target format, making it convenient for subsequent unified use.
It should be noted that batch conversion is not simply changing the file suffix to .mp4, but generating new MP4 files through the video conversion function. The significance of this is that the file format itself is processed according to the target format, rather than just modifying the file name display. Therefore, in office file management, using a dedicated batch processing tool is more reliable than manually changing extensions.
Operating Steps: Using HeSoft Doc Batch Tool to Batch Convert Videos to MP4
Step 1: Enter Video Tools and select Convert video to MP4
After opening HeSoft Doc Batch Tool , you can see that the left navigation bar contains multiple office file processing categories, such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, and Video Tools, etc. Since the goal this time is to process video files, you need to first enter the Video Tools category on the left.
On the Video Tools page, the interface displays multiple video format conversion functions, including Convert video to MP4, Convert video to AVI, Convert video to MKV, and Convert video to MOV. According to the needs of this article, you need to click Convert video to MP4. The description for this entry is to batch convert video files to MP4 format, which precisely matches the requirement to uniformly output videos like MKV, AVI, MOV, and WEBM as MP4.
The operational purpose of this step is to tell the software that the target format for this batch processing is MP4. After selecting the correct function, the subsequently imported video files will all enter this task flow, rather than being converted to AVI, MKV, or MOV. For batch processing, confirming the target function in the first step is very important to avoid discovering the output format was selected incorrectly after importing a large number of files.
Step 2: Add the video files to be converted or import from a folder
After entering the Convert video to MP4 function, you can see two buttons at the top of the page: Add Files and Import Files from Folder. They are suitable for different file organization methods: if the videos are scattered in different locations, you can use Add Files to select them in batches; if all videos are already located in the same folder, using Import Files from Folder will be more efficient.
From the record list in the screenshot, you can see that the software has imported 9 video files, with names including Bus.mkv, Car.mkv, City_Night.avi, Overpass.mov, Park.webm, Running.avi, Stream.mov, Surfing.mov, and Traffic.avi. The table also displays information such as path, extension, creation time, and modification time, where the Extension column clearly lists source formats like mkv, avi, mov, webm.
The operational purpose of this step is to add all the video files to be converted into the task list and review them before conversion. It is recommended to focus on checking three types of information: first, whether the number of records matches expectations, as the summary in the screenshot shows the record count is 9; second, whether the names include all files that need to be converted; third, whether the extensions are indeed the video formats that need processing. The interface also has filtering, sorting, and single-item delete operations on the right side, making it convenient to check or remove files imported by mistake when there are many files.
Step 3: Click Next after confirming the list is correct
After confirming that the imported records are correct, you can click the Next button at the bottom of the page. The progress bar at the top of the interface shows that you are currently on Step 1 Select the records to be processed, followed by Step 2 Set the save location and Step 3 Start processing. This process design is well-suited for batch file processing: first determine the processing target, then determine the output location, and finally execute the task uniformly.
Before clicking Next, it is advisable to reconfirm whether all files are in the list, especially when importing from a folder, videos from the same directory that do not need processing might also be included in the task. If you find a file that does not need conversion, you can use the delete button in the operation column to remove it, or use the clear button to re-import. This can avoid generating unnecessary MP4 files after the conversion is complete.
Step 4: Set the save location to avoid overwriting or confusing original files
After entering Step 2, you need to set the save location for the converted MP4 files. Although the screenshot does not show the specific details of the save location page, the process bar clearly indicates that the software includes this step. For batch video conversion, the output location is crucial. It is recommended to choose a clear target folder, such as MP4 Output, Converted, or ProjectName_MP4, to facilitate subsequent verification.
If you wish to keep the original MKV, AVI, MOV, and WEBM files, it is recommended not to mix the output files with the original files, or at least save the conversion results in a separate folder. Doing this has two benefits: first, the original materials will not be accidentally deleted or confused; second, the converted MP4 files can be centrally checked, making it convenient for direct upload, sending, or archiving. When batch processing files, good output directory management is more important than a single conversion.
Step 5: Start processing and wait for the batch conversion to complete
After the save location is set, enter Step 3 Start Processing. At this point, the software will perform the conversion on multiple video files according to the task list, outputting the imported different video formats in a batch as MP4. Since video files are usually large, the conversion time will be affected by the number of files, video duration, resolution, and computer performance. It is recommended to keep the computer power supply stable during processing and avoid moving or deleting source files at will.
After the processing is complete, open the set output folder for verification. According to the post-processing effect image, you can see that the file extensions have uniformly changed to .mp4, and the type also shows as MP4 File. At this point, you can use these MP4 files for uploading to platforms, copying to colleagues, placing in databases, or continuing with editing.
Frequently Asked Questions and Precautions
1. Can I import videos in different formats at once?
Yes. From the task list in the screenshot, you can see that the same batch of imported files includes multiple extensions like mkv, avi, mov, and webm, while the target function is Convert video to MP4. This indicates that the process is suitable for uniformly converting multiple source formats to MP4, without needing to manually process them in separate batches by format. This is a significant time-saver for folders with mixed formats.
2. Why is it not recommended to directly change the suffix to MP4?
Directly changing .mkv, .avi, .mov, or .webm to .mp4 only changes the file name display and does not equal completing a real video format conversion. Many players or platforms may still be unable to recognize the file content. Using the video conversion function generates MP4 files according to the target format, which better meets the requirements for office delivery and long-term archiving.
3. What checks should be done before batch conversion?
It is recommended to first check if the files can be opened normally to avoid conversion failures caused by corrupted source files; then check the record count and file names in the task list to confirm no omissions or incorrect selections; finally, confirm that the output folder has sufficient space. Video files usually take up more space than documents or images, so reserving enough disk capacity before batch converting to MP4 can reduce the risk of processing interruptions.
4. Will the file names change after conversion?
From the effect preview, you can see that the converted files basically retain the main part of the original file name, with only the extension uniformly changed to .mp4, for example, Bus.mkv corresponds to Bus.mp4 after conversion, and Traffic.avi corresponds to Traffic.mp4 after conversion. This naming method makes it easy for users to quickly match the conversion results to the original materials and facilitates subsequent searching and management.
5. How to improve verification efficiency when there are many files?
In the task list, you can pay attention to fields like Extension, Name, Path, and Record Count. The screenshot also shows operation entries for filtering and sorting, which are suitable for assisting with checks when there are many files. For example, you can confirm through the extension whether there are formats that do not need conversion, or judge by the path whether the files come from the correct folder.
Summary: Leave repetitive video format conversion to the batch processing tool
Batch converting many video files to MP4 solves a very typical repetitive labor problem in office work: many files, mixed format sources, and time-consuming, error-prone manual individual conversion. Using the video conversion function of HeSoft Doc Batch Tool , you can first select Convert video to MP4 in Video Tools, then add files in batches or import files from a folder, set the save location after confirming the list, and finally start processing uniformly.
From the before-and-after processing screenshots, it is clear to see that the originally mixed MKV, AVI, MOV, and WEBM files were uniformly converted into MP4 files after batch conversion. For users who need to organize video materials, deliver project data, upload courses, or standardize enterprise file libraries, this batch processing approach can significantly reduce repetitive clicks and manual verification costs. It is recommended that the next time you encounter a batch of videos in different formats, you directly use the batch conversion process, letting the office software handle the mechanical operations, and spending your time on more valuable content judgment and business tasks.
