Mixing multiple image formats in the same folder can lead to repetitive operations for website uploads, asset archiving, and team delivery. This article uses HeSoft Doc Batch Tool as an example to introduce how to batch convert AVIF, BMP, PNG, JPEG, HEIC, GIF, and other images to WebP. The article includes previews of the before and after effects, feature entry instructions, file import checks, next steps for processing, and common considerations to help users quickly unify image formats.
When many teams organize website materials, the first problem they encounter is not the large number of images, but the variety of formats. Product images received by operations colleagues from suppliers might be in jpeg, transparent images exported by design colleagues might be in png, photos taken or transferred via mobile phones might be in heic, old projects might still retain bmp files, and materials downloaded from web pages could be in avif or gif. Mixing different formats in the same directory makes uploading, compression, archiving, and subsequent reuse less convenient.
If you are only dealing with one or two images, manual conversion is acceptable; but when a directory contains dozens or hundreds of images, opening and exporting them to WebP one by one becomes obvious repetitive labor. This article introduces a method better suited for office scenarios: using the image conversion feature in HeSoft Doc Batch Tool to batch convert multiple image formats to WebP at once. The software falls into the category of batch processing tools for office software, with its core value being the centralized completion of high-frequency, repetitive, and rule-defined file processing tasks, reducing manual clicks and repeated confirmations.
Applicable Scenarios: Why Unify Website Materials, Product Images, and Databases into WebP
WebP is commonly used in web images and online material distribution scenarios. For those responsible for content publishing, website maintenance, event page creation, or product data organization, unifying images into WebP offers several distinct advantages.
First, it facilitates standardized upload specifications. Many web projects establish image format specifications, requiring article featured images, cover images, and detail page images to use the same format whenever possible. If source file formats are chaotic, format organization is needed before publishing.
Second, it simplifies team handoffs. If a material package contains multiple extensions like png, jpg, jpeg, heic, bmp, gif, avif, the recipient often needs to filter and process them again. Batch converting to WebP beforehand makes the delivery directory clearer.
Third, it aids long-term archiving. Databases and material libraries prioritize consistency. After unifying the format, subsequent searching, migration, backup, and cloud synchronization become more orderly.
Fourth, it suits batch workflows. When image conversion is just one part of a larger process—for example, unifying the format first, then standardizing naming, and finally uploading to the system—using batch processing tools is more in line with office efficiency requirements than manual software.
Effect Preview: From a Mixed-Format Directory to Unified WebP Files
Let's first look at the folder before processing. There are 7 image files in the screenshot, with file names and formats being 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif respectively. As you can see, this is not an image package from a single source, but a typical mixed-format directory.

In practical work, such a directory brings several problems: some systems might not support heic or avif; some older formats like bmp might have larger file sizes; gifs, if used merely as static images, might also need unified conversion; although jpeg and png are common, they still need processing if the project requires WebP. Manual conversion is not only slow but also prone to missing a few images.
The processed screenshot shows that all files have been changed to .webp extensions, namely 1.webp, 2.webp, 3.webp, 4.webp, 5.webp, 6.webp, 7.webp. In other words, the original avif, bmp, png, jpeg, heic, gif and other formats have all been unified into the WebP format.

This result is very friendly for organizing website materials: file extensions are unified, the naming sequence remains clear, making it more straightforward for subsequent uploading to a content management system or handing over to front-end, design, or operations colleagues for continued use.
Operation Steps: Batch Converting Images to WebP
Following the order of the screenshots, here is how to complete the operation in HeSoft Doc Batch Tool . To make the process easier to replicate, it is recommended to first gather the images to be converted into one folder and confirm that these images are the ones to be processed this time.
Step 1: Find Image to WEBP in Image Tools
After opening the software, you can see the product name in the upper left corner is HeSoft Doc Batch Tool . The left navigation bar provides multiple categories covering office file processing scenarios like documents, spreadsheets, presentations, PDFs, texts, images, videos, and audio. Since the goal is image format conversion, you should enter Image Tools on the left.
After entering Image Tools, multiple image processing function cards are displayed in the interface. The screenshot shows several entries related to format conversion, such as Image to PNG, Image to BMP, Image to GIF, Image to JPEG, Image to JPG, Image to SVG, Image to TIF, Image to TIFF, Image to TGA, Image to AVIF, etc. To unify the images to WebP, you need to select Image to WEBP. The red arrow and prompt in the screenshot clearly point to this function.

The expected result of this step is to enter the correct batch conversion task page. When selecting the function, pay attention to the target format and avoid mistakenly clicking Image to JPG, PNG, or other formats. For requirements like SEO image optimization, website image format unification, and batch product image organization, the target should be WEBP.
Step 2: Import the Image Files to be Converted
After entering the Image to WEBP page, the top button area provides two clear import methods: Add Files and Import Files from Folder. If you are only selecting a few images, you can click Add Files; if a batch of images is already prepared in a folder, clicking Import Files from Folder is more efficient.
The table in the screenshot already has 7 files imported. The list is displayed by sequence number and includes information like Name, Path, Extension, Creation Time, Modification Time, and Actions. These fields allow you to quickly verify if the imported content is correct. For example, the name column shows 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif; the path column shows they are located in D:\test; the extension column shows avif, bmp, webp, png, jpeg, heic, gif respectively. The summary at the bottom shows a record count of 7, indicating there are 7 records to be processed in this task.

This step is crucial, as the prerequisite for batch processing is an accurate file list. It is recommended to complete the following checks before clicking next: confirm the record count matches the number of images in the folder; confirm no irrelevant images have been imported; confirm the extensions include the formats that need conversion this time; if there are files in the list that do not need processing, you can use the delete icon in the actions column to remove them. The interface also provides buttons like Filter and Sort, which can assist in finding and checking when there are many files.
Step 3: Click Next to Enter the Save Location Settings
After importing and confirming the files, there is a Next button at the bottom of the interface. The progress bar at the top of the page shows you are currently at Step 1 selecting records to process, followed by Step 2 setting the save location and Step 3 starting processing. After clicking Next, you will enter the output settings phase.
The significance of setting the save location lies in deciding where the converted WebP files will be placed. For batch processing of office files, it is recommended to output the results to a separate directory, so the original images and the result files are not mixed together, which also facilitates subsequent checking. Especially when the source files already contain WebP files with the same name, using an independent output directory can reduce the risk of overwriting or confusion.
Step 4: Execute Batch Conversion After Confirming Settings
After completing the save location setting, follow the process to the start processing stage. The software will batch generate WebP format files from the list according to the Image to WEBP task. After processing, open the output directory to view the results. Combined with the effect screenshots, you can see that the 7 files ultimately all have the webp extension and maintain the file name sequence from 1 to 7.
This step embodies the efficiency advantage of batch processing tools. Users do not need to individually perform AVIF to WebP, BMP to WebP, PNG to WebP, JPEG to WebP, HEIC to WebP, or GIF to WebP conversions; instead, they place these different format images into one list and let the software complete the conversion according to a unified rule. For those who frequently handle website materials, this method significantly reduces repetitive labor.
Common Problems and Precautions
1. Should the folder be organized before batch conversion?
It is recommended. Although the software can import files from a folder, to avoid misprocessing, it's best to establish a dedicated 'to-be-converted' directory in advance and place the images that need conversion this time inside. This makes importing clearer and facilitates comparing counts before and after processing.
2. How should the output directory be chosen?
It is recommended to choose a directory different from the source images. For example, if the source images are in D:\test, you can create a WebP output folder nearby. The advantage of this is retaining the original images for subsequent review; if the conversion results do not meet expectations, you can also re-execute the task.
3. What happens to files that are already WebP?
In the screenshot, 3.webp existed in the original folder, and 3.webp still appears in the processed results. Whether files that are already WebP need to be processed together depends on your workflow requirements. If you just want to ensure the entire batch appears in the output directory, you can import them together; if you wish to avoid duplicate conversion, you can filter out files that are already WebP before importing.
4. Does a GIF retain its animation after converting to WebP?
The screenshots only show the extension changes before and after format conversion, without displaying animation effects or parameter settings. Therefore, for scenarios involving animated GIFs, it is recommended to actually open and check after conversion to confirm the display effect meets usage requirements. For important materials, retaining the original GIF file is particularly necessary.
5. What content needs to be checked after conversion?
It is recommended to check three points: first, whether the number of output files matches expectations; second, whether the file names correspond to the original files, avoiding omissions or duplicate names; third, sample open a few images to confirm they display normally. For images to be uploaded to a website, you can also check before uploading whether the system correctly recognizes the WebP format.
Summary: Leave Repetitive Format Conversion to Batch Office Tools
Batch converting multi-format images to WebP is a highly practical workflow in website material organization, product image processing, and image archiving. Through HeSoft Doc Batch Tool , users can select Image to WEBP in Image Tools, import images in formats including avif, bmp, png, jpeg, heic, gif, verify the list, continue to set the save location, and start processing, ultimately obtaining unified WebP files.
Compared to opening and exporting images one by one, the advantages of batch processing lie in process stability, fewer operations, and easier verification of results. For office workers who routinely handle large volumes of files, this not only saves time but also reduces the risk of human omissions and format inconsistencies. If you are organizing a batch of image materials ready for uploading to a website or delivering to a team, you can follow these steps in this article to complete the batch WebP conversion first, then proceed with naming, categorization, and publishing tasks.
