When a folder contains images in formats such as avif, webp, png, jpeg, heic, gif, and bmp, manually converting each one to BMP can be time-consuming. This article uses HeSoft Doc Batch Tool as an example to explain how to use the image tools in office software to access the "Convert Images to BMP" feature, batch import image files, review the pending processing records, and follow the process to set the save location and start the conversion, helping users quickly obtain uniform BMP image files.
Many office scenarios aren't lacking methods for image conversion, but rather efficient, stable methods suitable for batch processing. For example, a project resource package might contain heic photos taken with a phone, webp images saved from web pages, png images exported from designs, compressed jpeg images, and a few avif, gif, or bmp files. If a business system requires uniform uploads in BMP format, the traditional approach usually involves opening images one by one in image software and saving them as bmp individually. This method is acceptable when the number of images is small, but once files number in the dozens or hundreds, it becomes obvious repetitive labor.
This article introduces a more suitable processing approach for office workers: using the batch image conversion feature in " HeSoft Doc Batch Tool " to convert multiple image formats to BMP in one go. Based on interface classification, this software belongs to the category of office software and document batch processing tools, focusing not just on single file editing, but on reducing repetitive operations through batch processing, helping users complete file organization, format unification, and document delivery more quickly.
The following will fully explain the operation method for batch converting multi-format images to BMP, following the order of actual screenshots, covering the pre-conversion file status, post-conversion effects, software operation entry points, file import, and processing considerations.
Applicable Scenarios: Images from Multiple Sources Need Unification to BMP Format
The need for batch image conversion to BMP typically arises when file sources are complex, submission formats are fixed, and the processing quantity is large. Unlike saving a single image as a different format, batch conversion emphasizes "processing a batch of files with a unified rule." The following scenarios are all suitable for using the method in this article.
First is office document submission. Certain units, departments, or business platforms require image attachments to be in BMP format to ensure consistent system reading. After collecting images from different channels, employees might get files with various extensions like avif, webp, png, jpeg, heic, gif, which need to be uniformly converted to bmp.
Second is image material archiving. Positions in design, administration, product, operations, and archive management often need to organize image materials. If image formats differ in each project folder, subsequent searching and processing become more difficult. Unifying a specified batch of images to BMP output makes handover and archiving clearer.
Third is legacy system compatibility. Some older software, specialized equipment, inspection systems, or internal platforms have limited support for new image formats, especially webp, avif, heic, which may not be directly previewed or imported. Batch converting to BMP in advance can reduce repeated communication caused by format incompatibility.
Fourth is test data preparation. Development, testing, image processing, and process verification work often require a batch of sample images in the same format. Using the batch image to BMP conversion feature can quickly organize mixed-format samples into a unified format, facilitating subsequent program reading or process verification.
Effect Preview: Inconsistent Formats in the Folder Before Conversion
In the screenshot before processing, you can see 7 image files within the same folder, with their file names and extensions being 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif. That is, the files to be processed are not in a single format, but are a mix of various common and new image formats.

This situation closely mirrors real office scenarios. For instance, avif and webp might come from web pages or new media materials, heic might come from phone photos, png from screenshots or design exports, jpeg from compressed photos, gif might be animated or simple graphic materials. Different sources lead to format inconsistency, and if subsequent submission requires BMP, batch format conversion becomes necessary.
In the pre-processing phase, it is recommended that users first gather the images needing conversion into a single folder. This allows direct batch addition via "Import files from folder" in the software, saving the time of selecting files one by one, and also facilitates quantity verification after conversion.
Effect Preview: Output Files After Conversion Are All BMP
The post-processing screenshot shows that the extensions of the 7 output files have all become .bmp, specifically 1.bmp, 2.bmp, 3.bmp, 4.bmp, 5.bmp, 6.bmp, 7.bmp. The original formats like avif, webp, png, jpeg, heic, gif were uniformly converted to BMP, and the file naming maintains the corresponding relationship, making it easy to trace from the original file to the conversion result.

This output result has two clear advantages. First, the format is unified, so there's no need to check if each file extension meets requirements during subsequent uploads, archiving, or delivery. Second, the file name sequence is clear: original 1.avif corresponds to 1.bmp, 3.webp corresponds to 3.bmp, making the pre- and post-conversion relationship intuitive, suitable for batch document organization.
It is important to note that BMP format typically results in larger file sizes, so the occupied space might increase after conversion. If the business requirement explicitly mandates BMP, this is normal; if the purpose is only web display or size reduction, other target formats should be chosen based on actual needs.
Operation Step 1: Enter the Image Tools Category in the Office Software
After opening the " HeSoft Doc Batch Tool " shown in the screenshot, first find "Image Tools" in the left function navigation. The software interface categorizes different types of batch office tasks, such as File Names, Folder Names, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. This categorization is suitable for office users to quickly locate functions by task type.

As this task is image format conversion, click "Image Tools" on the left. After entering, the page displays multiple image-related function cards, including Add Image Watermark, Image Effects Enhancement, Split Image into Multiple Small Images, and various target format conversion functions. Do not select the conversion entries for PNG, JPEG, JPG, WEBP, AVIF, or other formats here; instead, select "Image to BMP".
In the screenshot, the description of the "Image to BMP" card is "Batch convert image files to BMP format," which is fully consistent with the goal of this article. After clicking this card, you will enter the task page for batch conversion to BMP.
Operation Step 2: Enter the "Image to BMP" Task Page
After entering the function, the page title displays "Image to BMP," with a "Return to Main Panel" button on the upper left, indicating that you have entered the independent conversion task interface. The top of the page provides operation entries like "Add File," "Import files from folder," "Clear," "More," with the pending file list area below.

From the process prompts, it can be seen that the software divides the entire batch conversion process into 3 stages: Step 1 select the records to process, Step 2 set the save location, Step 3 start processing. This design is very important for batch file processing, as it allows users to confirm the file list before formal execution, avoiding mistakes.
If images are scattered in different locations, you can use "Add File" to select them in batches; if images are already organized in the same folder, it is recommended to use "Import files from folder." The latter is more suitable for batch conversion scenarios, especially when there are many files, as it reduces repetitive selection operations.
Operation Step 3: Batch Import avif, webp, png, jpeg, heic, gif, and Other Images
The list in the screenshot has imported 7 files, with the table listing the sequence number, name, path, extension, creation time, modification time, and operations. The file paths are all shown in the D:\test directory, with names sequentially being 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif. The extension column also clearly shows the original format of each file.
The focus of this step is not immediate conversion, but confirming "which files to process." In batch office software, the pending list is equivalent to a task checklist. Output results are reliable only if the list is accurate. Users are advised to check three pieces of information after importing: first, whether the record count matches the original file count; second, whether the extensions cover the image formats that need conversion; third, whether the path is the target folder.
The bottom of the screenshot displays "Summary Record Count: 7," consistent with the 7 files in the pre-processing effect image, indicating complete file import. If you find files in the list that don't need processing, you can use the delete entry in the right-hand operation column to remove them. If there are many imported results, you can also use the "Filter" and "Sort" buttons in the interface to assist viewing.
Operation Step 4: Click Next, Set Save Location
After confirming the pending records are correct, click "Next" at the bottom of the page. At this point, the software enters Step 2 of the process, which is "Set save location." Although the screenshot does not show the details of the subsequent page, it can be reasonably inferred from the page flow prompt that the save location is a key step that must be confirmed before conversion.
For batch image to BMP, it is advisable not to arbitrarily select an output directory. A safer approach is to create a separate folder for the conversion results, such as "BMP Results," "Image to BMP Output," or create an output directory based on the project name. This has several benefits: first, original images and converted BMPs will not be mixed; second, it's easy to check the number of conversion results; third, you can directly package the output folder for subsequent delivery; fourth, if reconversion is needed, it won't affect the original files.
When setting the save location, also pay attention to disk space. Since BMP files are usually larger, the disk where the output directory resides needs sufficient space, especially if there are many images. The increase in file size is common, particularly when converting from JPEG, WEBP, AVIF to BMP.
Operation Step 5: Start Processing and Verify Conversion Results
After completing the save location setting, proceed to Step 3, "Start Processing." The software will convert the images to BMP format one by one according to the records in the pending list. Users do not need to open images individually, manually change extensions, or repeatedly perform save-as operations.
After processing is complete, open the output directory to verify the results. Refer to the post-processing screenshot to confirm that all files have been unified to the .bmp extension and check that the file count matches the number of imported records. For example, if 7 records were imported in this case, 7 BMP files should be obtained after conversion. If used for formal submission, it is recommended to randomly open a few images to confirm the content displays properly.
It must be specifically emphasized here that format conversion cannot be completed by simply manually changing file extensions. Directly renaming .webp, .heic, or .png to .bmp does not actually change the image encoding format and might instead cause the file to be unopenable. The correct approach is to use conversion functions like "Image to BMP" to allow the software to perform the actual format conversion.
Frequently Asked Questions and Considerations
1. Will batch converting to BMP change the original file names?
Judging from the post-processing effect, the main file names remain consistent; only the extensions are uniformly changed to .bmp. For example, 1.avif becomes 1.bmp after conversion, and 4.png becomes 4.bmp. This naming method facilitates correspondence between original files and conversion results.
2. What if there are already bmp files in the folder?
If you want the output results to be a complete set of BMP files, you can import the existing bmp files together. In the example, 2.bmp was also in the pending list, and the final output result still contains 2.bmp. This ensures the output directory content is complete without manual supplementation.
3. Can GIF retain animation after converting to BMP?
BMP is a static bitmap format, while GIFs may contain animation. The goal of batch conversion to BMP is to obtain BMP image files, so if the original GIF was animated, the conversion result should typically be used as a static image. If the business needs to preserve animation effects, GIFs should not be uniformly converted to BMP.
4. In what situations is HEIC to BMP conversion suitable?
HEIC is common for phone photos and is inconvenient to open in some Windows environments or older systems. If phone photos need to be used in office systems that do not support HEIC, converting to BMP is a compatibility solution. However, be aware that BMP file sizes can be large, so confirm the business really requires this format before conversion.
5. How to reduce the risk of errors before batch processing?
It is recommended to first back up the original images centrally before batch conversion; check the record count, path, and extensions after importing; set an independent output directory; and verify the file count and extensions after conversion. For important files, you can test with a small number of samples first, then batch process all files.
Summary: Delegate Image Format Unification to Office Software with Batch Conversion
When image quantities are large and format sources are complex, converting to BMP one by one is not only inefficient but also prone to missed conversions, naming confusion, and save location errors. Using the "Image to BMP" feature of " HeSoft Doc Batch Tool ", you can add files like avif, webp, png, jpeg, heic, gif, bmp into a unified task list, then follow the steps to set the save location and start processing, ultimately obtaining BMP files with consistent extensions.
The core value of this method lies in batch processing files, reducing repetitive labor, and improving office efficiency. For users needing to organize image materials, submit system attachments, ensure compatibility with old software, or prepare test materials in a uniform format, it is highly recommended to adopt the batch image to BMP process: first organize the original folder, then enter Image Tools and select "Image to BMP", import files and verify records, and finally set the output directory to execute the conversion. This not only saves significant manual operation time but also makes the conversion results more standardized, verifiable, and easy to deliver.
