When a folder contains multiple image formats such as AVIF, WEBP, PNG, JPEG, HEIC, and GIF simultaneously, opening each one individually and saving them as BMP can be very time-consuming and prone to oversight. This article uses HeSoft Doc Batch Tool as an example to explain how to use the image tools in office software to batch convert multiple images to BMP format, and illustrates the conversion results through before-and-after effect images, helping users quickly complete tasks such as image format unification, material archiving, and system compatibility processing.
In daily office work, file archiving, system uploads, image asset delivery, or compatibility with older software, one problem often arises: a single folder contains a mix of various image formats—for example, avif, webp, png, jpeg, heic, gif—and even some that are already bmp files. If you only need to deal with one or two images, manually opening an image editor and saving as BMP is acceptable; but when you need to process dozens or hundreds at once, repeating the operation not only wastes time but also leads to missed conversions, incorrect conversions, and chaotic file naming.
This article addresses the need for batch image format conversion of this kind: how to uniformly convert various image formats into bmp format. Using the office software " HeSoft Doc Batch Tool " as an example, and with accompanying screenshots, we will walk through the complete process from selecting the function and importing files to generating BMP images. This tool is positioned as a batch document and file processing office software, ideal for reducing repetitive work by handling tasks that would otherwise require per-file operations centrally.
Applicable Scenarios: When You Need to Batch Convert Images to BMP Format
BMP is a common bitmap image format. It is still required for use in some older systems, industrial software, reporting systems, recognition programs, printing workflows, or internal document management. Compared to some newer formats, BMP's compatibility is more stable in specific environments, which is why many office scenarios require standardizing assets as .bmp files.
For instance, materials received by a design department might come from different platforms; some might be WEBP, others PNG or JPEG. Pictures exported from a phone camera may be HEIC. Icons downloaded from the web might be AVIF or GIF. If the subsequent system only accepts BMP, manually converting each one creates a huge amount of repetitive work. Using a batch processing tool, you can import an entire folder or multiple images at once and output them all as BMP, significantly improving efficiency.
The sample files shown in this article's screenshots include 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif. You can see that these file extensions are inconsistent, which is a typical scenario for organizing mixed-format images.
Result Preview: A Mix of Various Image Formats Before Processing
Before conversion, the folder contains multiple image formats. The screenshot shows filenames arranged from 1 to 7, but with extensions of avif, bmp, webp, png, jpeg, heic, and gif, respectively. This means that although they are all image files, their formats are not uniform. If you need to submit them all as BMP files later, this state is inconvenient for direct use.
As seen in the pre-processing image, the original files may come from different sources: some might be landscape photos, others web graphics formats, and still others animations or new compression formats. Manually handling these formats often requires different software support, especially formats like HEIC, AVIF, and WEBP, which cannot be directly opened or saved in some older systems. With the batch conversion feature, you can let the software handle these differences automatically.
Result Preview: All Unified to BMP Format After Processing
After conversion is complete, the image extensions in the output folder have been uniformly changed to .bmp. The result shown in the screenshot is 1.bmp, 2.bmp, 3.bmp, 4.bmp, 5.bmp, 6.bmp, 7.bmp. The original formats like avif, webp, png, jpeg, heic, and gif have all been converted to BMP, with file sequence numbers kept consistent for easy verification and archiving.
This processed result is suitable for subsequent tasks like system uploads, standardizing material libraries, organizing files before batch printing, or preparing software test data. Files that were already BMP will also appear in the results in BMP format, making it convenient to consolidate all output files into a single format for management.
Step 1: Enter the Image Tool and Select the "Convert Images to BMP" Function
After opening HeSoft Doc Batch Tool , you can see multiple categories in the left toolbar, including Home, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. Since this task is an image format conversion, you need to enter the "Image Tools" category.
On the Image Tools page, the software provides various batch processing functions related to images. The screenshot shows functions like "Add Watermark to Images", "Enhance Image Effects", "Split Image into Multiple Small Images", "Convert Images to PNG", "Convert Images to BMP", "Convert Images to GIF", "Convert Images to JPEG", "Convert Images to JPG", "Convert Images to PSD", "Convert Images to SVG", "Convert Images to TIF", "Convert Images to TIFF", "Convert Images to WEBP", "Convert Images to TGA", "Convert Images to AVIF", etc.
The current goal is to batch convert images to BMP, so you need to click on "Convert Images to BMP". In the screenshot, this function card is highlighted and accompanied by the prompt "Batch convert image files to BMP format", indicating it is exactly the entry point for uniformly converting multiple images to BMP. After selecting the correct function, the software will enter the corresponding processing page.
Step 2: Add the Image Files You Want to Convert
After entering the "Convert Images to BMP" page, the current function name is displayed at the top, and the upper right provides action buttons like "Add Files", "Import Files from Folder", "Clear", and "More". The core task here is to add the images to be converted to the processing list.
If the number of images to process is small, you can click "Add Files" and select specific images from the local drive; if the images are all in the same folder, it is more recommended to use "Import Files from Folder", which allows you to import all images from the folder into the list at once, reducing repetitive selection actions. If you import incorrectly, you can also use "Clear" to start over.
The list in the screenshot has already imported 7 records. All file paths are located under the D:\test\ directory, with filenames 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif respectively. The list also displays information like extension, creation time, and modification time, making it convenient for users to check if the files are complete before conversion.
This verification step is very important. Although batch conversion is efficient, once incorrect files are imported, the software will proceed according to the list. Therefore, before clicking the next step, it is advisable to confirm that the record count, filenames, and extensions match expectations. The bottom of the screenshot shows "Summary Total records: 7", indicating that 7 image files will be processed.
Step 3: Confirm the Processing List and Proceed to the Next Step
After confirming the file list is correct, you can click the "Next" button at the bottom of the page. This button completes the current "Select records to process" stage and moves on to subsequent settings. The process prompt at the top of the page shows there are three stages: Step 1 is selecting the records to process, Step 2 is setting the save location, and Step 3 is starting the process.
After entering the next step, you will need to follow the software prompts to set the save location for the converted BMP files. It is recommended to choose an output folder different from the source files, such as creating a new directory specifically for the BMP results. The advantage is to avoid mixing original files with conversion results, making subsequent verification, packaging, and archiving clearer.
If the original files contain images with the same name but different extensions, like 1.png and 1.jpg, converting them both to BMP simultaneously might result in output files with identical names. Although the filenames in this article's screenshots have different sequence numbers, in actual office work, it's still advisable to check file naming beforehand or clearly differentiate the output directory to avoid the risk of overwriting.
Step 4: Set the Save Location and Start the Batch Conversion
Following the page flow, once the save location is set, you can enter the "Start Processing" stage. At this point, the software will perform format conversion on the files in the list one by one, outputting the imported images uniformly in BMP format. For the user, there is no need to open images individually or select the save-as format for each one; the entire process is handled automatically by the batch processing tool.
During batch conversion, it is recommended to keep the software running and avoid randomly moving the original files being processed or deleting the output folder. For tasks with a large number of files or large image sizes, the processing time may be longer than the example, which is normal. Wait for the task to complete, then go to the save location to view the generated results.
Looking at the post-processing screenshot, the conversion results have been unified to 1.bmp through 7.bmp. The original AVIF, WEBP, PNG, JPEG, HEIC, GIF, etc., formats in the list have all been organized into BMP files, achieving a unified image format.
Frequently Asked Questions and Important Notes
1. Do I need to process images that are already BMP? If the goal is to have all files in the output directory standardized as BMP, you can import and process them together. In the screenshot, the original 2.bmp remains 2.bmp after processing, which makes it easier to manage uniformly within the same result folder.
2. Will a GIF file remain an animation after converting to BMP? BMP itself is a static bitmap format and is not suitable for preserving animation effects. The result of converting a GIF to BMP should be understood as a static image. If the original GIF is animated, the converted result typically no longer plays the animation. The specific outcome depends on the actual file content and software processing results.
3. Why are formats like HEIC, AVIF, and WEBP suitable for batch conversion? These formats are common on web pages, phones, or newer systems, but their compatibility in some office systems, older software, or specialized programs may not be ideal. Batch converting to BMP can reduce format barriers for subsequent opening and uploading.
4. Should I back up the original images before conversion? It is recommended to keep the original images, especially for important photos, design materials, or client files. The goal of batch conversion is usually to generate a uniformly formatted copy, not to replace the original material. Selecting a new output folder when setting the save location is a safer practice.
5. How can I improve efficiency when dealing with too many files? You can consolidate all the images for a single batch conversion into one folder, then use "Import Files from Folder". Compared to adding them one by one, this method is more suitable for batch office tasks and less prone to omissions.
