Convert PNG to WebP
WebP files are usually a fraction of the size of the equivalent PNG and still support transparency, which makes them ideal for web pages. Convert a batch of PNGs with one click.
How to convert PNG to WebP
- Choose or drop your PNG files.
- Set the WebP quality — 90% or more is best for screenshots and graphics with text.
- Click Convert to WebP and compare the sizes, then download the files or the ZIP.
Supported formats
- Input
- PNG
- Output
- WebP
- Maximum size
- 50 MB per file (limited by your device's memory)
Benefits
- Keeps alpha transparency, unlike converting to JPG.
- Typically 50–80% smaller than the source PNG at high quality.
- Supported by all current browsers, so the files can be used on websites directly.
Limitations
- Output uses lossy WebP; the browser's encoder does not offer a strictly lossless WebP mode.
- Safari before version 14 and some older desktop apps cannot open WebP files.
- Encoding WebP requires a browser that supports it (Chrome, Edge, Firefox and Safari 17+ do).
Privacy and security
Images are decoded and re-encoded by your browser in a background Web Worker (or on the page itself in browsers without OffscreenCanvas). Files are never uploaded, and the results exist only in this tab's memory until you download them.

Frequently asked questions
Is WebP supported everywhere?
All current versions of Chrome, Edge, Firefox and Safari display WebP. Some older image editors and email clients don't, so keep the PNG for those uses.
Will my transparent background survive?
Yes. WebP supports full alpha transparency, so logos and cut-out images stay transparent.
How much smaller will my images be?
It depends on the content: photo-like PNGs often shrink by 80% or more, while simple flat graphics may shrink less. The tool shows the exact saving for each file.
