PNG to WebP Converter
Choose PNG files and each one is saved as a WebP on your device, usually at a fraction of the size.
Free tools that run in your browser. Nothing you type, open or create is uploaded to NerdBible or anyone else.
Choose one or more images to start. Nothing is uploaded.
Same format compresses each image and keeps its type. Choose JPG, PNG or WebP to convert every image to that format instead. Up to 50 images at a time.
How to use it
- Choose or drop one or more images.
- Keep Same format to make the files smaller, or choose JPG, PNG or WebP to convert them.
- Set the quality (70 to 80 suits photos) and, if you like, a max width: large photos shrink, smaller ones are never enlarged. For JPG, pick the colour that fills transparent areas; for SVG files, the width of the picture.
- Check the result for each file and download them one by one or all together.
Questions
Does WebP keep PNG transparency?
Yes. WebP supports an alpha channel, so transparent and semi-transparent areas are kept.
How much smaller will my images be?
It depends on the image. Photos and screenshots saved as PNG often shrink by well over half; simple graphics with few colours change less. Each file shows its before and after size.
Why did I get a PNG instead of a WebP?
Some browsers cannot save WebP from a web page. When that happens the tool tells you and keeps the PNG format. Try a current Chrome, Edge or Firefox.
About this tool
Why convert PNG to WebP
PNG files are lossless and can be very large, especially screenshots and photos saved as PNG. WebP can keep transparency like PNG while making the file much smaller, which helps pages load faster.
- Transparency survives. Clear areas in the PNG stay clear in the WebP, so logos and cut-outs still sit cleanly on any background.
- The quality slider matters. This converter saves lossy WebP. 75 to 85 suits most images; raise it for screenshots with small text.
- Savings vary. Photos and screenshots usually shrink the most. A small icon with a few flat colours can even come out larger, so compare the sizes shown.
Before you switch
Every current browser shows WebP, and most website builders and content systems accept it. Some older desktop programs and email clients still do not, so keep the PNG as your master copy. If your browser cannot save WebP, the tool says so and saves a PNG instead.
The WebP is redrawn from the pixels, so metadata in the PNG is not carried over.
