Convert PNG to WebP
Free, private, and instant — your files never leave your device.
WebP is Google's modern image format designed to replace PNG and JPEG on the web. In lossy mode, WebP files are typically 25–34% smaller than equivalent PNGs; even in lossless mode, WebP is about 26% more compact than PNG. Crucially, WebP supports full alpha-channel transparency — the same as PNG — so converting from PNG to WebP is usually a safe drop-in replacement for web assets. All modern browsers (Chrome, Firefox, Edge, Safari 14+) support WebP natively.

Frequently Asked Questions
Does WebP support transparency like PNG?
Yes. WebP has full alpha-channel support, including partial (semi-) transparency. Your transparent PNG areas will remain transparent in the WebP output, making WebP a direct replacement for PNG in web projects.
How much smaller will the WebP be than the PNG?
Typically 25–34% smaller in lossy mode for photographic or mixed content, and about 26% smaller even in lossless mode. Results vary by image — solid-color illustrations compress differently than detailed photographs.
Do all browsers and apps support WebP?
All major modern browsers — Chrome 23+, Firefox 65+, Edge 18+, and Safari 14+ — support WebP natively. Most modern image editors also support it. Legacy software, some email clients, and older operating systems may not, so keep a PNG copy if broad compatibility is important.
Should I switch from PNG to WebP for my website?
For images served in a browser, yes — WebP offers meaningfully smaller files with comparable visual quality. Use the HTML <picture> element with a WebP source and PNG fallback if you need to support Safari < 14 or IE. For non-web use (print, desktop apps, editing workflows), PNG remains the safer choice.
