How to Batch Convert WebP Images: Complete Guide 2025
Published on August 23, 2025 | Updated: August 23, 2025 | Reading time: 12 minutes
Quick Summary: Need to convert hundreds of WebP images at once? Batch conversion is the answer! This comprehensive guide covers the best free online tools, powerful desktop software, and efficient command-line methods to convert multiple WebP files to JPG, PNG, or other formats quickly and easily.
WebP is an incredibly efficient image format for the web, offering superior compression and quality. However, its compatibility isn't universal across all software, platforms, or older systems. This often leads to the need for conversion, especially when dealing with a large number of files.
Batch conversion allows you to process multiple WebP images simultaneously, saving you significant time and effort compared to converting them one by one. This is particularly useful for:
Website Migration: Converting images from a WebP-heavy site to one that requires JPG/PNG.
Offline Use: Preparing WebP images for software that doesn't support the format natively.
Archiving: Storing images in a more universally compatible format for long-term access.
Sharing: Sending images to clients or colleagues who might not have WebP-compatible viewers.

Method 1: Online Batch Converters (Easiest)
Online tools are the most accessible way to batch convert WebP images. They require no software installation and work directly in your web browser. Many free options are available.
Our Recommendation: For a fast, secure, and free solution that processes files locally in your browser (ensuring privacy), use our Bulk WebP Converter. It allows you to drag and drop multiple WebP files and convert them to JPG, PNG, or other formats without uploading them to a server.
Here's how to use a typical online batch converter:
1Choose a Reliable Online Converter: Search for "batch webp converter" on Google. Popular options include Convertio, CloudConvert, or Online-Convert.
2Upload Your WebP Files: Click the "Upload" or "Choose Files" button and select all the WebP images you want to convert. Most tools allow you to select multiple files at once.
3Select Output Format: Choose your desired output format (e.g., JPG, PNG, GIF).
4Adjust Settings (Optional): Some tools offer options like quality settings, resizing, or adding watermarks.
5Convert and Download: Click the "Convert" or "Start Conversion" button. Once the process is complete, you'll usually get a ZIP file containing all your converted images.
Privacy Note: While convenient, online tools require you to upload your files to their servers. If your images contain sensitive information, consider using offline desktop software instead.
Method 2: Desktop Software (Offline & Powerful)
For larger batches, regular conversions, or when privacy is a concern, desktop software is the superior choice. These applications run locally on your computer and offer more control.
Option A: XnConvert (Windows, Mac, Linux)
XnConvert is a free, powerful, and cross-platform batch image processor that supports hundreds of formats, including WebP for both input and output.
1Download and Install: Get XnConvert from its official website (xnview.com/en/xnconvert/).
2Add WebP Files: Open XnConvert, go to the "Input" tab, and add your WebP files or entire folders.
3Set Output Format: Go to the "Output" tab. In the "Format" dropdown, select your desired output (e.g., JPG, PNG).
4Configure Options: Adjust quality, resize, add watermarks, or apply other actions in the "Actions" tab.
5Convert: Click the "Convert" button. Your converted images will be saved to the specified output folder.
Option B: IrfanView (Windows)
IrfanView is a very fast, free, and compact image viewer for Windows that also excels at batch conversions. You'll need to install the full plugins package for best results.
1Download and Install: Get IrfanView and its plugins from irfanview.com.
2Open Batch Conversion Dialog: In IrfanView, go to File > Batch Conversion/Rename... (or press B).
3Add Files: In the "Input files" section, navigate to your WebP files and add them to the list.
4Set Output: Choose "Batch conversion" and select your desired output format (e.g., JPG, PNG). Set the output directory.
5Start Conversion: Click "Start Batch" to begin the conversion process.
Option C: GIMP (Windows, Mac, Linux)
While primarily an image editor, GIMP can also be used for batch processing, especially if you need to apply specific edits before conversion. You can use its built-in batch processing capabilities or a plugin like BIMP (Batch Image Manipulation Plugin).
Method 3: Command-Line Tools (Advanced)
For developers, power users, or those looking to automate the conversion process, command-line tools offer the most flexibility and speed.
Option A: `cwebp` and `dwebp` (Google's WebP Tools)
Google provides official command-line tools for encoding (`cwebp`) and decoding (`dwebp`) WebP images. These are part of the `libwebp` package.
1Install `libwebp`:
Windows: Download pre-compiled binaries from Google's WebP site or use a package manager like Chocolatey (`choco install webp`).
Mac: Use Homebrew (`brew install webp`).
Linux: Use your distribution's package manager (`sudo apt-get install webp` or `sudo yum install libwebp-tools`).
2Convert WebP to JPG/PNG using `dwebp`:
To convert a single WebP to PNG:
dwebp input.webp -o output.png
To convert a single WebP to JPG:
dwebp input.webp -o output.jpg
For batch conversion, you can use a simple loop in your terminal:
Windows (Command Prompt):
for %f in (*.webp) do dwebp "%f" -o "%~nf.png"
Linux/Mac (Bash):
for f in *.webp; do dwebp "$f" -o "${f%.*}.png"; done
Option B: ImageMagick (Cross-Platform)
ImageMagick is a powerful suite of command-line tools for image manipulation. It supports WebP and can handle complex batch operations.
1Install ImageMagick: Follow installation instructions for your OS from imagemagick.org.
2Convert WebP to JPG/PNG:
To convert a single WebP to JPG:
magick convert input.webp output.jpg
For batch conversion (converts all WebP files in the current directory to JPG):
magick mogrify -format jpg *.webp
Replace `jpg` with `png` for PNG conversion.
Best Practices for Batch Conversion
Backup Original Files: Always keep a backup of your original WebP files before performing any batch conversions.
Test with a Small Batch: Before converting hundreds of files, test the process with a small subset to ensure the output quality and settings are as expected.
Choose the Right Output Format:
Use JPG for photographs and images without transparency (smaller file size).
Use PNG for images with transparency, logos, or graphics with sharp lines (larger file size but preserves transparency).
Consider Quality Settings: If converting to a lossy format like JPG, adjust the quality setting. A quality of 80-90 is often a good balance for web use.
Organize Your Files: Create separate input and output folders to keep your files organized during and after conversion.
Frequently Asked Questions
Can I batch convert WebP to GIF?
Yes, most batch converters (online or desktop) that support WebP input can also output to GIF. However, remember that GIF only supports 256 colors and basic transparency, so quality might be reduced compared to WebP or PNG.
Is there a limit to how many files I can batch convert online?
Many free online converters have limits on file size or the number of files per batch. For larger batches, you might need to use a paid service or desktop software.
Will batch converting WebP files preserve transparency?
If your original WebP files have transparency, you must convert them to a format that also supports transparency, such as PNG. If you convert to JPG, transparency will be lost and replaced with a solid background (usually white or black).
How long does batch conversion take?
The time taken depends on the number of files, their size, your internet speed (for online tools), and your computer's processing power (for desktop tools). Online tools can be slower due to upload/download times, while desktop tools are generally faster for large batches.
Final Takeaway: Batch converting WebP images is a straightforward process with numerous free and powerful tools available. Choose the method that best fits your needs, whether it's the convenience of online converters, the power of desktop software, or the flexibility of command-line tools.
