Convert PNG to WebP for lighter graphics and photos
Turn PNG screenshots, graphics or photos into WebP and see the size saved. WebP can keep transparency, and its file sizes are often much smaller than PNG's.

How to use it
- Add your PNG files.
- Set the quality. For crisp graphics, use a higher value.
- Choose whether to keep metadata.
- Convert, compare sizes and download.
What it keeps
- Pixel dimensions.
- Transparency, which WebP can store.
What it removes or changes
- At normal settings WebP is lossy, so flat colours and text edges can pick up slight blur or noise that PNG did not have.
- Photos in PNG usually shrink a lot. Simple flat graphics may shrink less.
- Metadata is dropped unless kept.
Limits
- Pixel-perfect screenshots and pixel art are better left as PNG.
- Not all software opens WebP.
- Animated PNG is not treated as an animation.
Compatibility
Browsers show WebP and modern site builders accept it. If an image has to be used in older office programs, print workflows or upload forms, PNG remains the safe format. Test in the actual destination.
Privacy
Conversion runs in your browser tab. The PNG is not uploaded, and nothing is kept after you close the page.
When PNG is still the better choice
PNG is exact, and WebP at normal settings is not. For logos, UI screenshots, diagrams and pixel art, exactness matters and the PNG is usually small anyway. For photographs saved as PNG, WebP is the big win, because photographic content is where PNG is least efficient.
Troubleshooting
Text edges look soft.
Raise the quality, or keep this image as PNG.
The WebP is not much smaller.
Flat-colour PNGs are already efficient. Compare sizes and keep the smaller one.
The background is no longer transparent.
Check the destination app. Some old programs show WebP alpha incorrectly.
Frequently asked questions
Does WebP keep transparency?
It can store it, and the conversion carries it.
Is quality reduced?
At normal settings, yes, slightly.
Will it work on every site?
No. Current browsers show it, but some older programs and upload forms do not, so check the destination.
