This article explains how to use HeSoft Doc Batch Tool to batch convert multiple MP4 video files to WebM format. The article combines before-and-after effect images and software operation screenshots to illustrate the complete workflow: entering the video tool, selecting "Convert Video to WebM", adding files or importing a folder, confirming the pending processing list, setting the save location, and starting the process. It is suitable for scenarios such as organizing web video materials, compressing site resources, and batch unifying video formats.
In website construction, front-end page creation, online course material organization, or enterprise promotional material archiving, a very specific problem often arises: you have a batch of video files, mostly in MP4 format, but when publishing them on a web page, embedding them in a page, or handing them over to developers for use, they need to be uniformly converted to WebM format. If there are only one or two files, manual conversion is acceptable; but if there are dozens or even hundreds of videos, opening, exporting, and checking file names one by one will consume a lot of time and can easily lead to missed or incorrect conversions.
This article aims to solve the problem of "batch converting many video files to WebM format." The tool used here is HeSoft Doc Batch Tool , positioned as an office software. Its core value lies not in single-file editing but in the batch processing of documents, images, videos, audio, and other files, helping users reduce repetitive labor. The following sections, combined with screenshots, will explain the state before processing, the results obtained after processing, and how to complete the MP4 to WebM batch conversion step by step.
Applicable Scenarios: When do you need batch conversion to WebM
WebM is one of the common video container formats, often used in scenarios like web video display, H5 page materials, product official website motion graphics, and resource site video previews. For users who need to put videos on web pages, using WebM uniformly can make material management more standardized and facilitate subsequent front-end calls, archiving, and handover.
Common applicable scenarios include:
- Organizing web video materials: The design or operations team has a batch of MP4 materials that need to be converted to WebM before handing them over to development.
- Unifying enterprise data formats: Promotional videos, product demonstration videos, and training videos come from different sources and need to be uniformly output as WebM for centralized storage.
- Batch processing test files: During front-end testing, browser compatibility testing, or material library organization, there's a need to quickly generate WebM files with the same name.
- Reducing repetitive operations: Not wanting to switch back and forth between multiple conversion software or manually process videos one by one.
From the screenshots, it can be seen that the source files in this example are a group of MP4 videos named Video test 20, Video test 21, Video test 22, etc. The goal is to batch generate corresponding .webm files and try to keep the original file name structure clear.
Effect Preview: MP4 before processing, uniformly WebM after processing
Let's first look at the file status before processing. The folder contains multiple video segments, all with the .mp4 file extension, such as Video test 20.mp4, Video test 21.mp4, Video test 22.mp4, Video test 23.mp4, etc. The aspect ratios and content of different videos are not entirely identical; there are landscape videos and portrait videos, but they all belong to the category of materials requiring a uniform format.
After processing is completed, the same batch of videos is converted to WebM format, with the file names correspondingly changing to Video test 20.webm, Video test 21.webm, Video test 22.webm, Video test 23.webm, etc. This means that the result of the batch conversion is not just processing one specific file, but outputting multiple MP4 videos from the pending list as .webm files in one go.
This before-and-after comparison is very suitable for batch file processing scenarios: the original files can still be saved as source materials, while the converted WebM files are used for web publishing, project delivery, or unified archiving. For office users who frequently handle video materials, batch conversion is more stable than manual export one by one and makes it easier to verify the results.
Operation Steps: Using HeSoft Doc Batch Tool to Batch Convert to WebM
The following explains how to complete "Video to WebM" conversion in HeSoft Doc Batch Tool according to the operation sequence in the screenshots. The overall process can be understood as three steps: first select the function, then import the videos to be processed, and finally set the save location and execute the processing according to the process.
Step 1: Enter Video Tools, Select "Video to WebM"
After opening HeSoft Doc Batch Tool , you can see multiple category entries on the left side, such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PDF Tools, Image Tools, Video Tools, Audio Tools, etc. Since the current goal is to process video formats, you need to enter the Video Tools category on the left.
On the Video Tools page, the interface lists multiple video batch processing functions in card format, including Separating Picture and Sound from Video, Deleting Sound from Video, Adding Watermark to Video, Video to MP4, Video to AVI, Video to MKV, Video to MOV, Video to FLV, Video to WMV, Video to WebM, etc. According to the screenshot, the one you need to select is number 11, Video to WebM.
The operational purpose of this step is very clear: tell the software that the target format for this batch process is WebM. After selecting the correct function, the software will enter the corresponding processing page, and subsequently imported videos will be converted according to the logic of this function.
Step 2: Add Video Files to Be Converted
After entering the "Video to WebM" page, you can see the current function name displayed at the top. The page process is divided into three stages: "Select records to be processed," "Set save location," and "Start processing." The first stage is to add the videos to be converted into the pending list.
In the screenshot, there is an Add File button at the top, as well as a Import files from folder button. If you only want to select a few specific videos, you can use "Add File"; if a large number of MP4 videos are already centrally placed in a folder, using "Import files from folder" is more suitable, as this can reduce the operational cost of multi-selecting files.
After importing, the software will list the pending records in a table. The table in the screenshot contains information such as Sequence Number, Name, Path, Extension, Creation Time, Modification Time, and Operations. You can see that there are a total of 8 records in the list, and the extensions are all mp4, indicating that these files have been successfully added to this batch conversion task.
It is recommended to carefully check two things in this step: first, confirm that the number of files is correct, for example, the screenshot shows a record count of 8 at the bottom; second, confirm that the extensions match expectations, for example, mp4 in this case. If you find that videos that shouldn't be converted were imported, you can use the delete icon on the right side of the table to remove the corresponding records, avoiding unnecessary results.
Step 3: Click "Next," Set Save Location
After confirming that the pending list is correct, you can click Next at the bottom of the page. From the interface flow, the next stage is "Set save location." The purpose of setting the save location is to provide a clear output directory for the converted WebM files, making them easier to find, verify, and use later.
When batch converting files, the save location is very important. It is recommended not to randomly place the conversion results in unclear paths, but to establish a separate folder for this task, such as "WebM Output," "Web Video Materials WebM," "Converted Videos," etc. The benefit of doing this is: the source MP4 files and target WebM files are less likely to be confused, and it is more convenient for subsequent delivery to colleagues or uploading to project directories.
If you need to keep the original MP4 files, it is recommended to select a new output directory; if you are just testing the conversion effect, you can also choose a temporary directory, but be sure to organize it promptly after processing. For batch tasks in office scenarios, a clear folder structure is often more important than the single conversion speed, as it directly affects subsequent search efficiency.
Step 4: Start Processing and Check the WebM Output Results
After setting the save location, follow the software process to the "Start Processing" stage. At this point, the software will batch convert the videos in the list to WebM format based on the imported records. It is recommended to keep the source file paths accessible during the process and avoid moving or deleting the video files being processed to avoid affecting the conversion task.
After the conversion is complete, open the output directory to verify. Under normal circumstances, the original Video test 20.mp4, Video test 21.mp4, etc., will correspond to files like Video test 20.webm, Video test 21.webm, etc. You can check if the results are complete from three perspectives: file extensions, number of files, and the correspondence of file names.
Frequently Asked Questions and Notes
1. Will the original files disappear after converting MP4 to WebM?
According to the typical process of batch conversion, the conversion output usually generates new target format files. To avoid confusion, it is recommended to output WebM files to a separate directory and keep the original MP4s as source material backups. This way, even if you later need to convert to formats like AVI, MOV, MKV, FLV, you can still use the original files.
2. Why is it recommended to use "Import files from folder"?
When there is a large number of videos, selecting files one by one wastes time and is prone to omissions. "Import files from folder" is suitable for situations where materials are already centrally placed in the same directory. After importing, confirming the quantity and extensions through the list is more efficient.
3. Do file names need to be organized in advance?
It is recommended to organize them in advance. Although the software can batch convert formats, clear file names make the converted WebM files easier to identify. For instance, using product names, dates, sequence numbers, or purposes for naming is more suitable for team collaboration than default, messy file names.
4. What should be noted before batch conversion?
It is recommended to first confirm that the source files can play normally to avoid adding damaged videos to the task; also, confirm that there is sufficient disk space, as batch conversion will generate a batch of new files. If the number of videos is large, you can first test-convert with a small number of files, and proceed with batch processing all materials only after confirming the results meet the requirements.
