This article explains how to batch convert multiple images to AVIF at once for office users, suitable for processing image folders with mixed formats such as jpg, jpeg, png, bmp, webp, heic, gif, etc. Through screenshots of HeSoft Doc Batch Tool , it illustrates how to access the image tool, select images to convert to AVIF, import files, and check the task list, helping users replace manual "save as" operations with batch processing to improve image organization and delivery efficiency.
Many office users don’t work with just one image format when organizing picture assets. For example, materials received by the marketing department may be jpg, jpeg, or png; images exported from product documentation may be bmp; design or web assets may be webp; phone photos may be heic; and some icon or sticker assets may be gif. The more formats there are, the trickier subsequent uploading, archiving, compression, and distribution become.
If the goal is to unify these images into the AVIF format, manual operations are usually very inefficient. You may need to open image-editing software, import each image one by one, choose an export format, and finally confirm the save location and file name. Processing five images is still manageable, but once the number reaches dozens or hundreds, it takes up a lot of time and easily leads to omissions, duplicate saves, or messy file names.
This article introduces a more office-friendly approach: using the batch image-processing feature in “ HeSoft Doc Batch Tool ” to convert multiple images of different formats into AVIF in one go. The software is a tool designed for office file processing, focusing not on fine-tuning single images, but on batch file processing, reducing repetitive work, and improving the efficiency of daily file organization.
Applicable scenarios: which office tasks suit converting multiple images to AVIF
When you need to unify image formats, batch conversion is usually more stable and controllable than processing one image at a time. The following types of scenarios are especially suitable for using the image-to-AVIF feature.
First is web content publishing. When website editors publish articles, product pages, or help documents, they often need to organize images from different sources into a uniform format. The AVIF format is relatively common in web image optimization, and a unified conversion helps establish a fixed asset output standard.
Second is organizing corporate asset libraries. Internal promotional images, event photos, product screenshots, and training material pictures may come from different people and different devices, and the formats are often inconsistent. Batch converting to AVIF lets you output a batch of assets in a centralized way, making archiving and later retrieval more convenient.
Third is managing document images. When writing Word documents, PowerPoint presentations, PDF manuals, or online tutorials, you often need to organize a large number of screenshots and diagrams. If the image folder contains messy formats, later maintenance will be very inconvenient. After unified output as AVIF, they can be saved as an independent asset package.
Fourth is cross-platform image delivery. Some platforms have requirements for image format, size, or specifications. Although specific platform requirements vary, centrally converting images into the target format before official uploading is a very common office workflow.
Effect preview: from a mixed-format folder to unified AVIF output
The pre-processing screenshot below shows a set of images to be converted. You can see that 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, and 7.gif exist in the same directory at the same time. The sources and formats of the files are clearly different, which is also the most common state in actual office work.
If such a folder is directly handed over to a colleague or uploaded to a unified asset library, the recipient may need to organize it again later. In particular, formats like bmp, heic, and gif may require additional processing in certain usage scenarios. Rather than letting downstream workflows convert repeatedly, it is better to complete format unification once during the organizing stage.
The post-processing effect is shown below. You can see that all files have become .avif files, and the serial numbers remain consistent: 1.avif, 2.avif, 3.avif, 4.avif, 5.avif, 6.avif, 7.avif.
The advantage of this output result is very intuitive: on one hand, the file format is unified; on the other hand, the correspondence of file names is not disrupted. The pre-processing 2.bmp corresponds to the post-processing 2.avif, and the pre-processing 5.jpeg corresponds to the post-processing 5.avif, making subsequent checks and delivery clearer.
Operation steps: converting multiple images to AVIF in one go
Based on the actual interface shown in the screenshots, the following describes the operation process from selecting a feature to importing files. The overall idea is to first enter the correct batch image-processing feature, then add the files to be processed to the list, and after confirming, proceed to the next step of saving and processing.
Step 1: Open the software and enter the “Image Tools” category
After launching HeSoft Doc Batch Tool , you can see several file-processing categories on the left, such as Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. Since this task involves image format conversion, you need to select “Image Tools”.
On the Image Tools page, the software lists multiple batch-processing capabilities in the form of feature cards. The screenshot shows features such as “Image to PNG”, “Image to BMP”, “Image to GIF”, “Image to JPEG”, “Image to JPG”, “Image to PSD”, “Image to SVG”, “Image to TIF”, “Image to TIFF”, “Image to WEBP”, “Image to TGA”, and so on.
The feature to select for this task is “15, Image to AVIF”, whose description reads “Batch convert image files to AVIF format”. This indicates that this entry is specifically for batch image-to-AVIF conversion, rather than only supporting a single file.
The expected result of this step is to enter the “Image to AVIF” task interface. Choosing the correct feature is critical because different conversion entries correspond to different output formats, such as PNG, JPG, WEBP, AVIF, etc. Don’t select the wrong one.
Step 2: Import the images to be processed
After entering the task interface, the page title will show “Image to AVIF”. The top-right provides operation entries such as “Add files”, “Import files from folder”, “Clear”, “More”, etc. For converting multiple images, there are usually two import methods.
If the images are scattered in different locations, you can use “Add files” to select multiple files and add them to the list as needed. This is suitable when you only want to process some of the images.
If the images are already placed in the same folder, it is more advisable to use “Import files from folder”. This better suits batch office-processing habits, especially when importing all images from a project folder in one go.
The screenshot shows that 7 files have been imported. The list displays each file’s serial number, name, path, extension, creation time, and modification time. Through these fields, users can confirm that the correct files have been added before conversion.
Step 3: Verify the record count, paths, and extensions
Before batch conversion, it is advisable not to rush into processing but to check the list first. The bottom of the screenshot shows “Total records: 7”, which corresponds to the 7 files in the pre-processing folder, indicating that the import count for this task is correct.
Then check the “Path” column. In the screenshot, the paths are concentrated under the D:\test\ directory, indicating that these files come from the same test folder. In actual office work, if you import images from a project folder, you should also confirm that the path is the target directory to avoid accidentally adding images from other folders.
Next, check the “Extension” column. The extensions in the screenshot include avif, bmp, webp, png, jpeg, heic, and gif. It is precisely because the formats are not unified that the AVIF conversion feature is needed for standardization. If the list contains files you do not intend to convert, you can use the delete icon in the “Actions” column on the right to remove that record.
Step 4: Click “Next” to proceed to set the save location
After confirming the list is correct, click the “Next” button at the bottom of the interface. The process prompt at the top of the page shows that the current workflow includes “Select records to process”, “Set save location”, and “Start processing”. Therefore, the next step takes you to the save location setting stage.
In office file processing, it is recommended to plan the save location in advance. A more prudent approach is to save the AVIF output files into a new folder, such as “AVIF Output”, “ProjectName-avif”, or a directory named by date. This will neither affect the original files nor facilitate comparing pre- and post-processing results.
After completing the save location setting, proceed to “Start processing”. The software will execute the format conversion in batch according to the task list. After processing, open the output directory and you will see that all images have been unified into .avif files.
Frequently asked questions or notes
1. Does batch conversion change the original file names?
From the post-processing screenshot, you can see that the output files retain the original serial-number naming, with only the extension uniformly changed to .avif. For example, 4.png appears as 4.avif after conversion. This helps users track the correspondence between original and output files by name.
2. Can bmp, png, webp, jpeg, heic, and gif be imported at the same time?
The task list in the screenshot shows that these extensions can appear simultaneously in the “Image to AVIF” processing records. In other words, users do not need to process them in batches by format; they can add multiple image formats to the same conversion task.
3. Will files that are already AVIF affect the batch task?
The pre-processing list contains 1.avif, and after processing 1.avif is still there. In actual use, if you do not want to reprocess files that are already AVIF, you can filter them before importing, or delete the relevant records from the task list. Whether to keep such files depends on your organizing goal.
4. What operation is recommended when there are a large number of files?
If you need to process a large number of images, it is advisable to first organize the source folder to ensure it contains only the images that need to be converted this time. After importing, verify through the record count, paths, and extensions. Before formal batch processing, you can also test the output with a small number of files first, and after confirming they are correct, process all images.
5. Why shouldn’t I just change the file extension?
Directly renaming .png or .jpg files to .avif is not equivalent to truly converting the image format. The correct approach is to use the image format conversion feature to let the software perform the actual encoding and output. Otherwise, the file may not open properly or be recognized by other systems.
Summary: Replace multiple manual “Save As” actions with one batch process
The key to converting multiple images to AVIF in one go lies not in complex operations, but in choosing the right batch-processing workflow. HeSoft Doc Batch Tool breaks this process into clear steps: enter Image Tools, select “Image to AVIF”, import files, check the list, click next to set the save location, and start processing.
For office users, the greatest value of this method is reducing repetitive work. Whether you are dealing with jpg, jpeg, png, bmp, webp, heic, or gif, you can add them all to the task list and let the software output them as AVIF uniformly. This not only saves time but also reduces the risk of missed conversions, incorrect saves, and chaotic naming.
If you are organizing a batch of images with mixed formats, it is recommended to first gather the original images into one folder, then follow the steps in this article to batch convert them to AVIF. After processing, check the file count and extensions in the output directory, and you will get a set of image assets that are more standardized and easier to deliver.
