In office work, it is often necessary to convert all images in a folder to BMP format for importing into legacy systems, archiving documents, printing processes, or software compatibility testing. This article focuses on the practical need of batch converting folder images to BMP, and introduces how to use HeSoft Doc Batch Tool to complete the operation, including selecting the convert images to BMP function, importing multi-format images, verifying the processing list, setting the save location, and generating results, helping users reduce the repetitive work of converting images one by one.
Many users encounter image format conversion issues not just with a single image, but with a folder filled with images in various formats. For example, images downloaded from the web might be in webp, those exported from a phone might be heic, ones sent by a design colleague could be png, a client may provide jpeg files, and some system screenshots or historical materials could be in bmg, gif, or avif. Faced with such a mixed folder, if the subsequent platform only requires BMP format, converting them one by one becomes a very mechanical and repetitive task.
This article introduces a more office-oriented processing method: using HeSoft Doc Batch Tool to batch convert various images in a folder to BMP format. It is not just a simple image viewer, but an office software designed for batch document and file processing. Its core value lies in centralizing and streamlining repetitive operations, helping users save time on organizing files. The following will provide a complete explanation of the specific steps, combined with screenshots from before processing, during operation, and after processing.
Applicable Scenarios: Why Unify Folder Images to BMP
In daily office work, BMP is not the smallest image format, but it is still common in certain specific environments. For instance, some internal management systems, industrial control software, legacy applications, image recognition programs, print-related processes, or document submission specifications might explicitly require uploading .bmp files. If original image formats are inconsistent, format consolidation is needed first.
Unifying folder images to BMP is suitable for the following scenarios: First, when archiving project materials, images from different sources need to be unified into a single format; Second, during software testing, a batch of BMP images needs to be prepared as test samples; Third, older systems cannot recognize new formats like WEBP, HEIC, AVIF and require conversion before import; Fourth, for internal departmental document delivery, having consistent file extensions is desired for easier checking and batch management.
The traditional method typically involves opening an image, choosing Save As, specifying the BMP format, confirming the save location, and then repeating the same operation for the next image. The more files involved, the higher the probability of errors. By using a batch conversion tool, the user only needs to select the function, import files, set the output location, and leave the rest of the conversion process to the software.
Effect Preview: Inconsistent Formats in the Folder Before Conversion
First, let's look at the folder's state before processing. The screenshot shows 7 image files, named 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, and 7.gif. Although they can all be categorized as image materials, their extensions are clearly different.

This type of folder is quite common in practical work. For example, AVIF and WEBP are often seen in web images; PNG is commonly used for transparent backgrounds or screenshots; JPEG is common for photos; HEIC often comes from phone shots; GIF might be from animations or emoticons; and BMP might be a format already used by a historical system. If all these files need to be submitted to a system that only accepts BMP, format conversion must be completed first.
From a management perspective, inconsistent formats can also increase communication costs. The recipient might need to repeatedly remind about file upload restrictions, and the creator would have to search again for unconverted images. The significance of batch conversion is to eliminate these discrepancies all at once.
Effect Preview: All File Extensions Changed to BMP After Conversion
After the conversion is complete, the images in the result folder have been unified to BMP format. The post-processing screenshot shows that the extensions of all 7 files have become .bmp, with corresponding file names 1.bmp, 2.bmp, 3.bmp, 4.bmp, 5.bmp, 6.bmp, and 7.bmp.

This outcome facilitates subsequent processing. For example, a user can directly submit the output directory to a business system, package the BMP images to send to a colleague, or save them as a unified-format media library. Compared to the original folder, the processed file list is clearer, the extensions are consistent, and checking them is more intuitive.
Operation Step 1: Access the Image Tools Category in the Office Software
After opening HeSoft Doc Batch Tool , you can see the tool category navigation on the left side of the software. The screenshot shows categories including Home, Task Flow, All Tools, Document Name, Folder Name, Organize Files, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, and More Tools.
As this task involves image format conversion, you need to click "Image Tools" on the left. After entering, the main area will display function cards related to batch image processing. It's not limited to converting to just one format, but provides multiple image processing entries, such as adding watermarks to images, enhancing image effects, splitting images into multiple smaller images, and converting images to PNG, BMP, GIF, JPEG, JPG, PSD, SVG, TIF, TIFF, WEBP, TGA, AVIF, etc.

Among these functions, select "Image to BMP". In the screenshot, this card is shown as "5. Image to BMP", with a description below reading "Batch convert image files to BMP format." This indicates the function is suitable for converting multiple image files to BMP at once, rather than handling just a single file.
Operation Step 2: Import Images from Folder into the Processing List
After clicking "Image to BMP", the software enters the corresponding task page. The current function name is visible at the top of the page, with buttons like "Add Files," "Import Files from Folder," "Clear," and "More" on the right side. For the task of unifying folder images to BMP, it is recommended to prioritize using "Import Files from Folder," as this can centrally add images from the target folder into the task list.

If you only need to process a few images, you can use "Add Files" to select them manually. After importing, the table will list the pending records. The table fields in the screenshot include Number, Name, Path, Extension, Creation Time, Modification Time, and Operation. Using these fields, users can confirm whether the correct files have been imported before conversion.
In the example, the imported path is D:\test\, and there are 7 records in the list, corresponding to the extensions avif, bmp, webp, png, jpeg, heic, and gif. The bottom summary shows "Record count: 7", indicating that the current batch task will cover these 7 files. For a large number of office files, it is recommended to carefully check the record count at this step to avoid missing images in the folder or mistakenly adding unrelated images to the task.
Operation Step 3: Use List Information to Check Files for Conversion
The advantage of batch processing is its speed, but it also means that preliminary checks are critical. After importing the images, do not rush to start processing; instead, first look at the names and extensions in the table. In this article's example, 1.avif, 3.webp, 4.png, 5.jpeg, 6.heic, and 7.gif all need conversion to BMP; 2.bmp is already in BMP format, but to keep the output directory complete, it can also be included in the process.
If a record is found unnecessary, you can use the delete icon in the "Operation" column to the right of the list to remove it. The screenshot shows a red cross-shaped operation entry to the right of each record for removing the corresponding item from the current task list. This allows you to adjust the scope of this batch process without affecting the original files.
The page also provides "Filter" and "Sort" buttons. If the list is very large, you can use these entries to assist in reviewing the records. Note that this article only explains functional entries based on the visible interface in the screenshots and does not expand on advanced rules without screenshot demonstration. In actual use, users can filter or sort according to the interface prompts for faster file verification.
Operation Step 4: Click Next and Set the Save Location for BMP Files
After confirming the processing list, click the "Next" button at the bottom of the page. The page flow shows that the entire task is divided into three stages: select the records to process, set the save location, and start processing. The current screenshot is at the first stage; clicking next will lead to the save location setting.
When setting the save location, it is recommended to choose a new output folder, for example, creating a folder like "BMP Results" or "Converted BMP" next to the original directory. This keeps the original AVIF, WEBP, PNG, JPEG, HEIC, GIF files separate from the converted BMP files, making comparison and backtracking easier. Once the conversion results are confirmed correct, you can archive or submit them as needed.
For corporate office files, preserving the original files is particularly important. The originals may contain formats more suitable for re-editing or compression, while the BMP files are mainly for compatibility and submission. Separating the output location from the originals reduces the risk of accidental deletion, overwriting, or confusion.
Operation Step 5: Start Processing and View the Conversion Results
After the save location is configured, enter the "Start Processing" stage. The software will then execute the batch image format conversion according to the task list, outputting the images in the list as BMP files. The user does not need to repeatedly choose the format for each image or confirm the save location one by one; they simply wait for the software to complete the processing.
After processing finishes, open the output directory to check the results. According to the post-processing screenshot, all files are now presented in .bmp form, indicating the goal of unifying multi-format images to BMP has been achieved. At this point, you can verify by file count. For example, in the example, there were 7 files before and 7 BMP files after processing, with matching counts and corresponding file name numbers.
If your actual folder contains more images, you can use the same checking method: first see if the number of output files matches the expectation, then spot-check if some images open normally, and finally confirm that all extensions are .bmp.
Common Questions and Considerations
1. Can PNG, JPG, JPEG, WEBP, HEIC, AVIF, and GIF be imported together? Based on the example screenshot, the list already contains extensions like avif, bmp, webp, png, jpeg, heic, and gif simultaneously, and they were unified using the "Image to BMP" function. Therefore, mixed-format images can be imported in the same batch task.
2. What is the difference between JPG and JPEG, and do they need to be handled separately during conversion? JPG and JPEG usually both refer to the JPEG image format; only the extension naming differs. The function area in the screenshot has both "Image to JPEG" and "Image to JPG," but since the current goal is to convert to BMP, there is no need to worry about whether the original is .jpg or .jpeg; just add it to the list of images for conversion.
3. Why is it recommended to use "Import Files from Folder"? When images are stored centrally in the same directory, using "Import Files from Folder" saves time compared to selecting them one by one and is more aligned with the batch processing concept. For dozens or hundreds of images, this method is more efficient than manual addition.
4. What happens to the file names after conversion? The post-processing screenshot shows that after conversion, the original files like 1.avif, 3.webp, 4.png correspond to 1.bmp, 3.bmp, 4.bmp, indicating the main name stays consistent while the extension changes to bmp. This helps users verify based on the original numbering or name.
5. What should you pay attention to before batch conversion? It is recommended to back up important original images first, confirm the pending processing list, choose a clear save location, and verify the output quantity after conversion. For very large images or numerous files, processing time might increase; just wait for the software to finish.
