This article explains how to use HeSoft Doc Batch Tool to batch convert avif, bmp, webp, png, jpeg, heic, gif, and other image formats to png format. The article combines before-and-after processing screenshots and the software interface, explaining the workflow of selecting a function, importing files, checking the list, setting the save location, and starting the process. It is suitable for users who need to unify image formats, organize materials, comply with system upload requirements, or reduce repetitive conversion tasks.
In daily office tasks, content operations, design collaboration, and file archiving, you often encounter the problem of inconsistent image formats: a single folder might contain avif, bmp, webp, jpeg, heic, gif, and other image formats simultaneously. Some platforms only support png uploads, some documents or systems have fixed requirements for image formats, and some images exported from phones, web pages, or design software come in various formats. Opening images one by one and resaving them as png is not only time-consuming but also prone to missed processing, incorrect filename changes, or overwriting original files.
This article addresses the high-frequency office problem of "how to batch convert various image formats to png format." With the help of the image tool in the office software " HeSoft Doc Batch Tool ", you can import images in multiple formats at once and uniformly convert them into png files. For users who need to process files in batches, reduce repetitive operations, and improve image organization efficiency, this type of batch processing function is more stable than manual conversion and is better suited for handling large volumes of materials.
Applicable Scenarios: When Do You Need Batch Image to PNG Conversion?
PNG is a very common image format in office and design scenarios, offering good compatibility and suitability for document illustrations, web page materials, system uploads, file archiving, and image re-editing. Converting images from different sources to a unified png format can reduce format compatibility issues in subsequent use.
The following scenarios are particularly suitable for using the batch image to png function:
- Mixed Material Formats: There are avif, webp, bmp, jpeg, heic, gif, and other images in a folder, and you want to organize them all into png format.
- Platform Upload Restrictions: Some backends, form systems, or document management systems only allow png uploads, and other formats cannot be used directly.
- Office Document Formatting: When creating Word, PPT, or PDF materials, you want all image formats to be consistent to reduce insertion failures or display anomalies.
- Mobile Image Processing: Some photos taken or exported from mobile phones are in heic format, which is inconvenient to open in Windows or some software, requiring conversion to png.
- Web Image Organization: Webp images downloaded from web pages have poor compatibility with certain tools; converting them all to png facilitates editing and archiving.
- Bulk Material Delivery: When positions like design, operations, customer service, or administration need to deliver image assets to others, a unified png naming convention is clearer.
Compared to single image conversion, the value of batch conversion lies in one-time import and unified processing of multiple files. It not only saves click effort but, more importantly, reduces the error rate caused by repetitive labor, standardizing the image organization workflow.
Effect Preview: How File Formats Change Before and After Processing
First, look at the file situation before processing. The example folder contains 7 images with the extensions avif, bmp, webp, png, jpeg, heic, and gif. This means the sources and formats of these images are not uniform. If they need to be uploaded to a system that only supports png, or delivered as a unified material package, format conversion is required first.
From the pre-processing screenshot, you can see the filenames are 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif. Among them, the 4th file is already in png format, but it can still enter the processing flow with other images and ultimately be kept as png output. The advantage of this is that you don’t need to manually filter beforehand; just put the images needing organization together for unified processing.
After processing is complete, the images in the folder have been uniformly converted to png format, with filenames showing as 1.png, 2.png, 3.png, 4.png, 5.png, 6.png, 7.png. This means images from different sources have been uniformly converted to png, making them more convenient for subsequent use, whether for uploading, formatting, archiving, or distribution.
From the post-processing effect image, you can intuitively see that the original extensions like avif, bmp, webp, jpeg, heic, gif have all become png. For batch organization of image materials, this result is very clear: the number of files remains consistent, the format is unified, and the naming rules are easier to recognize.
Operation Steps: Using HeSoft Doc Batch Tool to Batch Convert to PNG
The following describes the complete operation flow according to the interface order in the screenshots. The core of the entire process is: enter the image tool, select “Convert Image to PNG”, import the images to be processed, confirm the list, then set the save location and start processing.
Step One: Enter the Image Tool and Select “Convert Image to PNG”
After opening HeSoft Doc Batch Tool , you can see multiple office processing modules in the left function category, such as File Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, etc. Since the task is image format conversion, you need to enter the “Image Tools” on the left.
On the Image Tools page, you can see multiple function cards related to image batch processing, including Add Watermark, Image Enhancement, Split Image, 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, Convert to AVIF, and more. The goal here is batch png conversion, so select “Convert Image to PNG”.
The red arrow in the screenshot points to the “Convert Image to PNG” function. The function description is “Batch convert image files to PNG format”, which matches the requirement of this article. After clicking this function, the software will enter the specific processing page.
The operational goal of this step is to locate the correct image format conversion entry from the many office batch processing functions. The expected result after completion is entering the “Convert Image to PNG” task interface, preparing for adding image files later.
Step Two: Add Files or Import Images from a Folder
After entering the “Convert Image to PNG” page, you can see buttons at the top of the interface like “Add File”, “Import Files from Folder”, “Clear”, “More”, etc. For a small number of images, you can click “Add File” to manually select; if the images are already centrally located in one folder, it’s more recommended to use “Import Files from Folder”, which can save the time of selecting files one by one.
In this example, 7 image files were imported. The list displays information such as sequence number, name, path, extension, creation time, modification time, and operations. Through these fields, users can confirm before starting processing whether the files are fully imported, the formats meet expectations, and the paths are correct.
As seen from the screenshot, the imported records include 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif, with paths all located in the D:\test directory. The extension column clearly shows the original format of each file, and the summary area at the bottom shows the record count is 7, indicating there are 7 files waiting to be processed in this batch.
The operational goal of this step is to add all images needing conversion to the batch processing queue. The expected result after completion is that the pending records appear in the file list, and the record count matches the number of images the user prepared to convert.
Step Three: Check Pending Records, Filter, Sort, or Delete as Needed
Before officially starting the batch image to png conversion, it is recommended to check the import list. Especially when dealing with larger quantities, prior verification can avoid processing unnecessary files or missing some images.
The right side of the interface provides “Filter” and “Sort” buttons, and there is also a delete icon in the “Operations” column of the list. If a file item does not need processing, it can be removed via the operations column; if many files are imported, you can use filtering and sorting to assist viewing. The screenshot shows that each record displays the filename and extension, which is very useful for confirming whether formats like avif, webp, heic, gif have been imported.
The operational goal of this step is to complete a quality check before conversion. The expected result after completion is that only the image files that need to be converted to png remain in the list, avoiding unexpected final output.
Step Four: Click “Next” to Enter Save Location Settings
After confirming the pending records are correct, you can click the “Next” button at the bottom of the page. As seen from the interface progress bar, the current processing flow is divided into three stages: Select records to process, Set save location, Start processing. The current screenshot is at Step 1; clicking “Next” will proceed to Step 2.
The significance of setting the save location is to determine where the converted png files will be placed. When batch processing files, it is recommended to choose a clear output directory, such as creating a “PNG Output”, “Converted Images”, or a folder named after the project. This facilitates separate management from the original images and reduces the risk of accidental overwriting or deletion.
The operational goal of this step is to move from the file selection stage to the output settings stage. The expected result after completion is that the software enters the save location configuration interface, allowing the user to specify the storage location for the converted png images.
Step Five: Set the Output Location and Start Processing
After setting the save location, proceed to the “Start Processing” stage. The software will convert each image file to png format based on the imported list and output them to the specified location. For files that were already png, they typically also participate in the output as png results, ensuring the final format of the whole batch is consistent.
During the batch conversion process, users do not need to open images one by one or individually choose “Save As”. The value of batch processing in office software lies in handing repetitive actions over to the tool; users only need to confirm the input files and output location before starting.
After processing is finished, you can open the output folder to view the results. Looking at the effect images in this article, the original 1.avif, 2.bmp, 3.webp, 4.png, 5.jpeg, 6.heic, 7.gif have been uniformly changed to 1.png, 2.png, 3.png, 4.png, 5.png, 6.png, 7.png.
Frequently Asked Questions and Precautions
1. Do I need to import images that are already PNG?
If your goal is to make all image formats in a folder consistent, you can import png images together. This way, after processing, the output directory will yield a batch of png files with uniform extensions, which is convenient for delivery and archiving. If you only want to convert non-png images, you can also filter them yourself before importing.
2. Why is it recommended to convert formats like WEBP, HEIC, AVIF to PNG?
WEBP, HEIC, and AVIF have advantages in compression and storage, but they can have compatibility issues in some office software, older systems, upload platforms, or collaborative environments. PNG has better universality and is suitable for documents, presentations, material packages, and system uploads. Converting webp to png, heic to png, and avif to png can reduce subsequent occurrences of opening or insertion failures.
3. Will a GIF still be animated after converting to PNG?
PNG is a static image format and is not equivalent to the GIF animation format. If the original file is a gif, converting it to png usually results in a static image. For scenarios where preserving animation effects is necessary, you should carefully choose the output format based on your actual usage.
4. Why set a save location before batch conversion?
Batch processing generates multiple files at once. Setting a separate save location separates the original images from the converted png files, making it easy to check results and avoiding overwriting or mixing up files with the same name. Especially when processing client materials, project images, or course materials, it is recommended to use an independent output folder.
5. How to reduce the probability of errors when dealing with a very large number of files?
It is recommended to first gather all images needing conversion into the same folder, then batch add them via “Import Files from Folder”; after importing, check the record count and extensions; confirm the output location before starting processing; and spot-check a few images after completion to see if they open normally. This forms a stable batch image format conversion workflow.
Summary: Unifying Image Formats Through Batch Processing is More Efficient
Batch converting various image formats to png essentially solves a common file standardization problem in office work. Whether it’s converting avif to png, webp to png, heic to png, or uniformly converting formats like bmp, jpeg, gif, manual single-image processing is not suitable for scenarios with a large number of files.
Through the “Convert Image to PNG” function in HeSoft Doc Batch Tool , you can import multi-format images at once, and after list confirmation, save location setting, and starting processing, quickly obtain unified png files. For users who frequently organize image materials, create documents, upload system data, or process project files, this batch processing method can significantly reduce repetitive labor and improve file processing efficiency.
If you currently have a batch of images in mixed formats that need to be unified into png, it is recommended to gather the images into one folder first, then follow the steps in this article to open the image tool, select “Convert Image to PNG”, import the files, and start batch processing. This allows you to complete image format unification more quickly and makes subsequent office workflows smoother.
