This article is aimed at users who need to convert various image formats to BMP format in batch. It demonstrates how to use HeSoft Doc Batch Tool to batch convert AVIF, WEBP, PNG, JPEG, HEIC, GIF, and other images to BMP. Combining before-and-after processing screenshots and the software operation interface, the article explains the complete workflow from selecting the "Convert Images to BMP" function, importing image files, checking the list, to continuing to set the save location and starting the process. It is suitable for scenarios such as data archiving, system compatibility, and image material organization.
In daily office work and material management, image sources are often very complex: photos taken with a phone may be HEIC, downloads from the web may be WEBP, design assets may be PNG or GIF, while system screenshots or images exported by older software could be BMP, JPEG, etc. If later they need to be used by a business system, legacy software version, inspection program, or image processing workflow that only supports the BMP format, opening each image one by one and saving as BMP is not only time-consuming but also prone to missed or incorrect conversions.
The problem this article aims to solve is: how to batch convert a group of image files in different formats into a unified BMP format. The following uses HeSoft Doc Batch Tool as an example, demonstrating the operation workflow from function entry to file import with screenshots. It is a batch processing software designed for office scenarios, and its core value lies in centralizing repetitive file processing actions, reducing the time cost and error rate caused by manual one-by-one operations.
Applicable Scenarios: When Do You Need to Batch Convert Images to BMP
BMP is a relatively common bitmap format, which is still required for use in some older systems, industrial software, image recognition programs, exam registration systems, archival systems, or specific office workflows. For individual users and enterprise office workers, batch converting images to BMP typically occurs in the following types of scenarios.
First, standardizing formats for archival requirements. Some organizations, when organizing historical images, ID photos, scanned documents, engineering drawings, or training materials, require all images to use a unified file extension for easier system identification and long-term preservation. If formats like avif, webp, png, jpeg, gif, and heic coexist in a folder, subsequent retrieval and use become inconvenient.
Second, business systems that only accept BMP images. Some older systems or specialized software have strict format restrictions when uploading images and only allow the bmp format. In such cases, if the number of images is large, manual conversion takes up significant time. Batch conversion tools are more suitable, especially when dozens or hundreds of images need processing.
Third, unifying multi-source materials for delivery. Roles in design, operations, administration, and teaching often collect images from different sources. To deliver them to downstream personnel or import them into other programs, batch converting to BMP first reduces the risk of format incompatibility.
Fourth, avoiding omissions caused by manual conversion. When saving images one by one using an image viewer, more files increase the likelihood of duplicate processing, missed processing, and naming confusion. By processing them in batch with office software, you can review the file list and confirm the record count before execution.
Preview of Results: Mixed Image Formats Before Processing, Unified as BMP After
In the pre-processing screenshot below, the same folder contains multiple image formats, including 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif. As you can see, the extensions of these images are inconsistent, and the compatibility of some formats varies across different software or systems.
After batch conversion, the processed files all become the BMP format. The original avif, webp, png, jpeg, heic, gif images have been uniformly output as 1.bmp, 2.bmp, 3.bmp, 4.bmp, 5.bmp, 6.bmp, 7.bmp. For scenarios requiring upload, archiving, or import into a designated system, this unified format result is more convenient for subsequent use.
Operation Steps: Using HeSoft Doc Batch Tool to Batch Convert to BMP
The following explains the specific operations in the order of the screenshots. Since the software interface uses a wizard-style workflow, users only need to first select a function, then import the images to be processed, and then follow the steps to set the save location and start processing.
Step 1: Enter Image Tools and Select the "Convert Image to BMP" Function
After opening HeSoft Doc Batch Tool , you can see "Image Tools" in the function categories on the left. After entering this category, the interface lists multiple image-related batch processing functions, such as Add Watermark to Image, Enhance Image Effects, Convert Image to PNG, Convert Image to BMP, Convert Image to GIF, Convert Image to JPEG, Convert Image to JPG, Convert Image to PSD, Convert Image to SVG, Convert Image to TIF, Convert Image to TIFF, Convert Image to WEBP, Convert Image to TGA, Convert Image to AVIF, etc.
The current goal is to convert various image formats to BMP, so you need to click "Convert Image to BMP." In the screenshot, this function is the 5th item on the list and has a descriptive note saying "Batch convert image files to BMP format." The purpose of this step is to enter the dedicated BMP conversion workflow and avoid selecting the wrong target format in other image conversion functions.
After selecting this function, the software enters the "Convert Image to BMP" processing page. The top of the page shows the workflow steps, including "Select records to process," "Set save location," and "Start processing," indicating that the entire conversion process is not an instant single-file operation but rather about building a task list first and then executing uniformly.
Step 2: Add the Image Files to Be Converted
After entering the "Convert Image to BMP" page, the first thing to do is import the images to be processed. The upper right area of the interface provides two entry points: "Add Files" and "Import files from folder." If the number of images is small, or you only want to select a few specific images, you can use "Add Files"; if all images in a folder need to be converted to BMP, you can use "Import files from folder."
As seen in the screenshot, 7 files have been imported this time, and the list displays information such as sequence number, name, path, extension, creation time, modification time, and actions. The imported files include 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif, and the extension column correspondingly shows avif, bmp, webp, png, jpeg, heic, gif. This shows that the software can put images of different formats into the same task list for unified processing.
The expected result of this step is: all images to be converted appear in the list, and the "Summary" section at the bottom shows the correct record count. The record count in the screenshot is 7, indicating that 7 image files will be processed this time.
Step 3: Check the File List, Delete, Filter, or Sort if Necessary
Before batch processing, it is recommended to check the file list. There is an "Actions" column on the right side of the list, with a delete icon next to each record. If a file is found unnecessary for conversion, it can be removed from this task via that location. You can also see "Filter" and "Sort" buttons at the top of the page, which are suitable for assisting in finding and organizing records when there are many files.
The purpose of this step is not to convert files, but to confirm whether the batch task is accurate. Especially when importing files from a folder, the folder might contain images that do not need processing. Checking in advance can avoid outputting unnecessary BMP files.
Step 4: Click "Next" to Enter Save Location Settings
After confirming the list is correct, click the "Next" button at the bottom of the page. According to the workflow prompts at the top of the page, the next step is "Set save location." This step is used to determine where the converted BMP images will be saved. It is recommended to choose an easily identifiable output location, such as creating a new dedicated BMP output folder, to avoid mixing them with the original images.
Although the screenshot does not show the specific interface for the save location setting, it is reasonable to infer from the workflow steps that the software will let the user confirm the output path in the second step. For office scenarios, saving the conversion results separately makes it easier to verify, preserves the original files, and reduces the risk of accidental overwriting or mixing up files.
Step 5: Start Processing and Verify the Output Results
After completing the save location settings, proceed to the "Start processing" step. After execution, the software will batch output the images in the task list to the BMP format. Once processing is complete, you can open the output folder to view the results, confirm whether the extensions have been unified to .bmp, and check if the number of images matches the imported record count.
In this example, there were 7 files before processing and 7 corresponding BMP files after processing, indicating the batch conversion results are complete. For files that need to be submitted to a system or delivered to colleagues, you can directly use the processed BMP versions.
Common Questions and Precautions
1. Does an image that is already BMP need processing? From the example, it can be seen that the task list includes 2.bmp. During batch conversion, files already in BMP format can also appear in the list. Whether to keep such files depends on your organizational needs. If you want all images in the output folder to have a uniformly generated BMP result, you can keep them; if you only want to convert non-BMP files, you can remove the already-BMP files from the list before processing.
2. How will the filenames change after conversion? From the result image, it can be seen that the processed filenames still retain the original number body, such as 1, 2, 3, etc., but the extension is uniformly changed to .bmp. This result makes it easy for users to check the before-and-after conversion relationship based on the original file sequence.
3. Why is it recommended to check the record count first? When batch processing files, the record count is key to verifying task completeness. The summary record count in the screenshot is 7, and 7 BMP files are obtained after processing. If the count before and after import is inconsistent, it might indicate that some files were not added, were deleted, or there are other files in the output location, requiring further checks.
4. Why convert formats like HEIC, WEBP, and AVIF to BMP? These formats are common in web browsing, mobile phones, and new image scenarios, but not all office systems can recognize them. Converting HEIC to BMP, WEBP to BMP, and AVIF to BMP can improve usability in specific software, especially suitable for scenarios requiring a unified submission format.
5. Is it recommended to overwrite the original files directly? A safer practice is to save the conversion results in a new folder. This preserves the original images for later traceability. If the BMP files are confirmed correct, you can archive or delete the original files based on actual needs.
Summary: Use Batch Processing to Reduce Repetitive Save-As Operations
Batch converting images to BMP is essentially about handing over a large number of repetitive actions like "open image, save as, select BMP, save" to office software for centralized completion. HeSoft Doc Batch Tool , through the "Convert Image to BMP" function in "Image Tools," allows users to import multiple images like AVIF, WEBP, PNG, JPEG, HEIC, GIF at once, and follow the workflow to set the save location and uniformly output BMP files.
If you are organizing a batch of images with mixed formats, or need to submit images to a system that only supports BMP, it is recommended to follow the steps in this article to first import the files, verify the record count, and then execute the batch conversion. This saves time and reduces the probability of omissions and format errors that occur with manual one-by-one processing.
