When a folder contains a mix of BMP, JPEG, WEBP, PNG, HEIC, GIF, and other image formats, converting them one by one to AVIF can be very inefficient. This article uses the image-to-AVIF conversion feature of HeSoft Doc Batch Tool to explain the complete workflow, from selecting a tool, importing images, verifying the file list, setting the save location, to starting the process, and demonstrates the conversion results with before-and-after screenshots. Suitable for users who need to unify image formats, optimize asset management, and improve office efficiency.
Many people encounter a similar problem when organizing image assets: pictures come from different devices and platforms—phone photos might be in HEIC, web downloads in WEBP, design exports in PNG or JPEG, and historical archives may contain formats like BMP and GIF. When the file count is small, manual conversion seems acceptable; but once your asset directory holds a large number of images, opening and re-saving each one as AVIF becomes highly inefficient, repetitive work.
This article addresses that exact problem: how to batch convert multiple image formats within a single folder to AVIF. We will use screenshots from HeSoft Doc Batch Tool to explain the complete process—from entering the Image Tools, selecting the Image to AVIF conversion feature, importing files, and proceeding to the next step. This software is positioned as an office tool, and its core advantage lies in batch file processing, making it suitable for delegating repetitive manual file conversion tasks to a tool.
Use Cases: Why You Need Unified Conversion for Mixed Image Formats
In practical work, a mix of image formats is often not accidental. For example, content managers collecting article images from multiple sources often receive different formats like JPG, JPEG, PNG, and WEBP. Cross-border e-commerce teams organizing product images might receive HEIC or BMP files from suppliers. Web projects aiming to optimize loading speed may require all source materials to be uniformly converted to AVIF. When a company archives promotional materials internally, they also likely want all file extensions to be consistent for easier retrieval and management.
Without a unified format, several problems can arise in subsequent work. First, some systems may not accept certain image formats, requiring on-the-fly conversion before uploading. Second, a messy mix of extensions in a folder makes filtering and statistics inconvenient. Third, during multi-person collaboration, different members may use different conversion methods, leading to inconsistent outputs. Fourth, converting files one by one takes a considerable amount of time; the efficiency of manual operation is extremely low, especially when dealing with hundreds of images.
The AVIF format is becoming increasingly common in web images and lightweight storage scenarios. Batch converting images like BMP, JPEG, WEBP, PNG, HEIC, and GIF to AVIF can make your asset library more uniform and reduce subsequent repetitive operations. With batch-processing office software, users don't need to master complex image processing skills; they only need to add files to the task list according to the workflow.
Result Preview: The Pre-Conversion Folder Contains a Mix of Extensions
The 'before' screenshot below shows the original images for this example. As you can see, there are 7 files in the folder, with inconsistent extensions including avif, bmp, webp, png, jpeg, heic, and gif. This mixed state closely mirrors a real office environment: some files come from old systems, some from the web, some from a phone's photo album, and some may be output from design or screenshot tools.
From a management perspective, a folder with mixed formats is not conducive to batch uploading, unified compression, or long-term archiving. For instance, if you want to filter all images usable for web publishing, you constantly need to determine which formats require further processing. If you need to send them to a colleague or client, they might have problems opening them due to differing device or system support. Therefore, centrally converting these images to AVIF is a more efficient way to organize them.
Result Preview: Files are Unified to AVIF Format After Conversion
The 'after' screenshot shows that all images with different original extensions have been output as AVIF files. The converted file names are 1.avif, 2.avif, 3.avif, 4.avif, 5.avif, 6.avif, 7.avif. This means the original 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, and 7.gif were all converted to corresponding AVIF files.
This processing result offers two obvious benefits. First, the output file names are clear and maintain a one-to-one correspondence with the original files, making them easy to check. Second, with unified extensions, subsequent tasks—whether uploading to a project directory, adding them to an asset library, or sharing them with other colleagues—become easier to manage. For office teams that frequently handle images, batch conversion can significantly reduce the time spent on format management.
Operation Steps: Enter Image Tools and Find the AVIF Conversion Entry
After launching HeSoft Doc Batch Tool , you can see the software's left side is divided into multiple tool categories based on file type and office scenario. This task involves image processing, so you need to select the Image Tools on the left. Once entered, the main interface displays a series of batch functions related to images, including adding watermarks, enhancing image effects, splitting an image into multiple smaller images, and various image format conversion features.
In the format conversion area, you'll see functions like Convert to PNG, Convert to BMP, Convert to GIF, Convert to JPEG, Convert to JPG, Convert to PSD, Convert to SVG, Convert to TIF, Convert to TIFF, Convert to WEBP, Convert to TGA, and Convert to AVIF. Since the goal this time is to output all images as AVIF, you should click on Convert to AVIF.
The purpose of this step is to first determine the processing type for the batch task. Batch processing in office software doesn't usually end by just dragging files in; you first select the processing rule and then import the target objects. After selecting the correct target format, the subsequently added images will be output according to the AVIF rule. If you mistakenly select PNG, WEBP, or JPEG, you'll get results in different formats, so be sure to confirm the feature name before proceeding to the next step.
Operation Steps: Import the Images for Batch Conversion
After entering the Convert to AVIF page, the top provides action buttons like Add File, Import from Folder, Clear, and More. The interface also displays three process nodes: Select Records to Process, Set Save Location, and Start Processing. This workflow design is easy for office users to understand, as it breaks down the batch conversion into three clear stages.
If you are selecting only a few specific images, you can use Add File; if all assets are already in a single directory, using Import from Folder is more recommended. In the example, the imported file path is the D:\test directory, and the list contains 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif, with the extension column also showing avif, bmp, webp, png, jpeg, heic, gif. The summary at the bottom shows a record count of 7, indicating that this batch task has successfully read 7 files.
At this step, it's recommended not to rush into clicking 'Next', but to first review the list content. Focus on whether the file names are complete, the paths are correct, and the extensions match expectations. If you find images that don't need conversion have been imported, you can remove the corresponding records in the operation column; if the entire list is incorrect, you can use Clear and re-import. Batch processing is highly efficient, but only if the task list is accurate. Checking before conversion can avoid rework later.
Operation Steps: Set the Save Location to Avoid Overwriting and Mixing
Once the file list is confirmed to be correct, click the 'Next' button at the bottom of the page to enter the set save location phase. The interface workflow has marked the second step as 'Set Save Location,' which means the software requires you to determine the output directory before formal processing begins. For batch image-to-AVIF conversion, the save location is very important, as it relates to whether the original files are easily kept and whether the converted files are easy to find.
It is recommended to save the output results to a separate folder, for example, creating a new 'AVIF' or 'AVIF Output' directory beside the original one. The advantage of this is that the original BMP, JPEG, WEBP, PNG, HEIC, and GIF files are still retained, while the converted AVIF files are stored separately, keeping the structure clear before and after processing. If you later need to compare image quality, reconvert, or locate a specific source file, you can do so quickly.
In an office scenario, many mistakes are not caused by the conversion itself, but by a confusing save path. For example, after placing output files back into the original directory, users find it difficult to distinguish which are the originals and which are the converted results; or during multi-person collaboration, it's unclear which version to use. Planning the save location in advance makes the batch-converted files easier to deliver and reuse.
Operation Steps: Start Processing and Verify the Output Files
After completing the save location settings, continue to the start processing step. Since the Convert to AVIF function was previously selected and the file list already contains the pending records, the software will batch execute the conversion according to the current task rules. For the user, there is no need to open images one by one or individually select output formats; just wait for the batch processing to complete.
After processing, it is recommended to check the results against three criteria. First, check if the number of output files matches the task list. In the example, 7 files were imported, so you should also get 7 AVIF files after processing. Second, check if all extensions are .avif. Third, spot-check a few images to see if they can be opened normally, especially files originally in HEIC, GIF, or WEBP format, as their support status can vary across different environments.
Judging from the post-processing screenshot, the file names retain their original sequence numbers, with only the extension uniformly changed to avif. This output method is very business-friendly, as it maintains the file correspondence while achieving format unification. If you later need to use these images for web pages, document asset libraries, or project delivery, you only need to use the AVIF files in the output directory.
FAQ: Things to Note Before and After Batch Image to AVIF Conversion
1. Is AVIF suitable for all image usage scenarios?
AVIF is commonly used for web optimization and image size control, but the degree of support for AVIF may vary across different software, systems, or platforms. Before conversion, you should first confirm whether the target platform supports AVIF. If used for internal archiving, it is also recommended to ensure that common image viewers can open it.
2. Can JPEG, JPG, PNG, and WEBP be placed in the same batch task?
As seen in the task list in the screenshot, images with different extensions were placed in the same conversion task, including bmp, webp, png, jpeg, heic, gif, etc. Therefore, in practice, you can import multiple image formats centrally and then convert them uniformly to AVIF.
3. Do images that are already AVIF still need processing?
In the example, 1.avif also appeared in the task list. For files that are already AVIF, if you want the entire directory to be processed through the same workflow, you can keep them in the task; if you don't need reprocessing, you can also remove them from the list. It depends on your specific organizing rules.
4. Is it more appropriate to use Add File or Import from Folder?
For a small number of images, using Add File is better for precise selection; for a large number of images or when an entire directory needs conversion, using Import from Folder is more efficient. The principle of batch office work is to reduce repetitive selections, so the advantage of importing a folder becomes more obvious as the file count increases.
5. How to avoid file chaos after conversion?
The simplest method is to set a dedicated output folder and verify the results based on quantity, extensions, and a preview check after processing. Do not directly replace the original source materials with unconfirmed conversion results, especially in team collaboration or client delivery scenarios; keeping the source files is even more important.
Conclusion: Leave Repetitive Image Format Conversion to Batch Office Tools
Batch converting multi-format images to AVIF might seem like just a file format conversion issue, but it actually relates to the efficiency of asset organization, web publishing, team collaboration, and long-term archiving. Manual, image-by-image conversion consumes a great deal of time and is prone to errors due to repetitive operation. HeSoft Doc Batch Tool provides a Convert to AVIF feature, which, through the workflow of selecting a function, importing files, setting a save location, and starting processing, turns originally scattered manual operations into a controllable batch task.
If your folder contains a mix of BMP, JPEG, JPG, PNG, WEBP, HEIC, GIF, and other image formats and you wish to unify them into the AVIF format, you can follow the method in this article: first select Convert to AVIF in the Image Tools, then import files or folders, verify the task list, set the output location, and finally start processing and check the results. This not only reduces repetitive work but also makes image file management more standardized. For office users who frequently handle a large volume of files, developing a habit of using batch processing tools will significantly improve daily work efficiency.
