When a folder contains multiple image formats such as avif, bmp, webp, png, jpeg, heic, and gif at the same time, opening them one by one and saving them as JPEG is not only very time-consuming, but also easy to miss some files. Using HeSoft Doc Batch Tool as an example, this article demonstrates how to use the image tool in office software to batch convert multiple image formats to .jpeg files in one go, and illustrates the conversion results through a before-and-after comparison. It is suitable for scenarios such as data archiving, image uploading, cross-platform compatibility, and unified management of team materials.
In daily office work, material organization, website content maintenance, or project archiving, we often encounter a typical problem: a single folder contains a mix of various image formats, such as AVIF, BMP, WEBP, PNG, HEIC, GIF, and even some JPEG images. Different platforms, systems, or business processes have inconsistent support for image formats; some platforms cannot directly preview HEIC, some backends do not support WEBP or AVIF, and some document collaboration workflows prefer a unified JPEG format. At this point, if you manually open and save each image as JPEG one by one, it's not only inefficient but also easy to miss several files.
This article aims to solve the problem of "how to batch convert various image formats to JPEG format." Using screenshots and the office software " HeSoft Doc Batch Tool " as an example, it will explain the complete process from selecting the function, importing images, checking the file list, to continuing the processing. This tool is positioned as an office software for batch file processing, suitable for handling repetitive, mechanical, and error-prone format conversion tasks in a centralized manner, thereby reducing manual operation time.
Applicable Scenarios: When do you need batch JPEG image conversion
Batch image to JPEG conversion is not only for designers. Many common office scenarios also encounter the problem of inconsistent formats. For example, photos taken with a phone might be HEIC, materials downloaded from a webpage might be WEBP, historical files might be BMP, images exported by design or compression tools might be AVIF, and some systems only allow uploading JPEG or JPG. To ensure these images can be displayed normally on more devices, documents, backend systems, and communication tools, uniformly converting images to JPEG is a common and practical solution.
As seen in the screenshot, the pre-processing folder contains files like 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif, with very mixed format sources. If these files are used for project archiving, client material submission, webpage content upload, or internal document illustrations, unifying the format is often necessary first. The value of batch conversion lies in importing multiple files at once, where the software automatically recognizes extensions and processes them in batch, thus avoiding repeated clicks, saves, and renames.
Effect Preview: File changes before and after processing
First, look at the file status before processing. In the screenshot, you can see that the 7 image file extensions in the same directory are all different, including .avif, .bmp, .webp, .png, .jpeg, .heic, .gif. This means the user is facing the need to unify multiple image formats into JPEG, not just convert a single format.
After the conversion is complete, the processing result becomes very intuitive: the original 7 files all now have the .jpeg suffix, with the original file sequential numbers maintained, displayed as 1.jpeg, 2.jpeg, 3.jpeg, 4.jpeg, 5.jpeg, 6.jpeg, 7.jpeg. Such results facilitate subsequent uploads, archiving, copying to other devices, and unified viewing by team members.
It should be noted that the output format in the screenshot is JPEG, with the file extension shown as .jpeg. Many users ask whether JPEG and JPG are the same; from a daily usage perspective, both generally refer to the JPEG image format, differing only in the extension name. The software entry corresponding to the function shown in this article is "Convert Image to JPEG," and the output example is also a .jpeg file. Therefore, in actual operation, the result generated by the software should prevail.
Operation Steps: Using office software to batch convert images to JPEG
Step 1: Enter Image Tools and select "Convert Image to JPEG"
After opening HeSoft Doc Batch Tool , go to "Image Tools" from the left navigation bar. In the screenshot, you can see the tool list provides various batch processing functions related to images, such as adding watermarks, enhancing image effects, converting images to PNG, converting images to BMP, converting images to GIF, etc. To achieve the batch conversion of images to JPEG, you need to select the 7th item, "Convert Image to JPEG."
The purpose of this step is to first clarify the target format for this batch processing task. For batch processing software, choosing the correct function first is very critical because different entries correspond to different output formats. The function card description in the screenshot reads "Batch convert image files to JPEG format," which perfectly matches the requirement of this article. After selecting this function, the software enters the dedicated image-to-JPEG operation page.
Step 2: Add the image files to be converted
After entering the "Convert Image to JPEG" page, you can see buttons like "Add File," "Import Files from Folder," "Clear," and "More" at the top of the interface. If you only need to select a few images, you can use "Add File"; if the images are centrally stored in one folder, "Import Files from Folder" is more suitable, as it allows you to import multiple images from the same directory in one go, reducing the trouble of multiple manual selections.
From the second operation screenshot, you can see the software has imported 7 records, listed by index showing name, path, extension, creation time, modification time, and an action column. File path examples are D:\test\1.avif, D:\test\2.bmp, D:\test\3.webp, etc., and the extension column also clearly shows avif, bmp, webp, png, jpeg, heic, gif. For the batch conversion task, this list serves as a pre-processing confirmation checklist, helping users determine if the correct files were imported.
Step 3: Check the file list and filter, sort, or delete if necessary
Before officially starting the conversion, it is recommended to first check the number of files and extensions in the list. The screenshot bottom shows the record count is 7, indicating there are 7 files to be processed in the current task. There is a delete icon in the action column on the right; if you find an image that does not need conversion was imported, you can delete it in the corresponding row. The interface also displays "Filter" and "Sort" buttons, which are especially useful for scenarios with many files: when a folder has a large number of images, you can use the list to check, filter, and sort to confirm the processing scope and avoid mistaken processing.
The expected result of this step is: the pending records are accurate, all images needing conversion have been added to the list, and files not requiring processing have been excluded. Compared to manually opening images one by one, this tabular batch confirmation method is better suited for office scenarios because it allows users to centrally check file names, paths, and extensions before starting the task.
Step 4: Click "Next" to set the save location and start processing
There is a clear "Next" button at the bottom of the screenshot, and the progress bar at the top of the page also shows you are currently at Step 1 "Select records to process," followed by Step 2 "Set save location" and Step 3 "Start processing." Therefore, after confirming the list is correct, click "Next" to enter the save location setting phase. The save location setting determines where the converted JPEG files are output. It is advisable to choose an easily identifiable directory to avoid confusion with original files.
After completing the save location setting, proceed to the start processing phase. The software will batch convert the image formats according to the records in the current list. For the 7 images in this article's example, once the conversion is complete, you will see the unified .jpeg files in the output location. The expected result is the state shown in the previous effect preview: 1.jpeg through 7.jpeg are generated sequentially, and the originally mixed AVIF, BMP, WEBP, PNG, HEIC, GIF formats are unified to JPEG.
Common Issues and Notes
1. Will images that are already JPEG be processed?
The 5th file in the screenshot is itself 5.jpeg, which was also imported into the "Convert Image to JPEG" list. For images already in JPEG format, whether to continue processing depends on your organization goal. If your goal is to have all images in a folder run through the same output process, you can keep it; if you only want to convert non-JPEG files, you can check the list by extension after import and delete the records that don't need processing.
2. Can GIFs retain animation after conversion to JPEG?
JPEG is a static image format, whereas GIFs may contain animation. Converting a GIF to JPEG will usually result in a static image. The screenshot only reflects the format conversion result of "Convert Image to JPEG" and does not show any feature related to preserving animation. Therefore, if the original GIF is animated, confirm whether you only need a static image before conversion.
3. Why check the path and extension before starting?
The biggest advantage of batch processing is high efficiency, but it also means that if the import scope is inaccurate, a large number of unnecessary files might be processed at once. Confirming through the name, path, extension, and record count in the list can reduce the probability of operational errors. Especially when importing files from a folder, it's recommended to first be clear about the directory location and file types.
4. How should output files be named and stored?
Looking at the post-processing screenshot, the output files maintain the original sequential names and are unified with the .jpeg extension. For easier management, it is recommended to save the conversion results to a separate folder, such as a "JPEG Output" or "Converted to JPEG" directory. This facilitates comparison of before-and-after effects and avoids mixing them with the original files.
Summary: Unify image formats with batch processing tools to reduce repetitive labor
Converting various image formats like AVIF, BMP, WEBP, PNG, HEIC, GIF to JPEG in batch essentially solves compatibility and management efficiency problems caused by inconsistent file formats. Using HeSoft Doc Batch Tool , you can first select "Convert Image to JPEG" in the "Image Tools," then batch import images via "Add File" or "Import Files from Folder," check the list, click "Next" to set the save location, and start processing.
Compared to manually saving images one by one, batch conversion can significantly reduce repetitive labor, making it especially suitable for office scenarios with many images, mixed source formats, and the need for unified delivery or uploading. If you are organizing project materials, processing client images, or preparing images for website uploads, it is recommended to directly use the batch image-to-JPEG process and let the office software handle the format unification work.
