Frequently Asked Questions
How much smaller is WebP compared to PNG?
WebP lossless is typically 26% smaller than PNG. With lossy compression at high quality settings, reductions of 60-80% are common with minimal visible difference.
Will my transparent backgrounds be preserved?
Yes. WebP fully supports alpha channel transparency, so your transparent PNGs convert perfectly.
Should I convert PNG screenshots to WebP?
Yes — screenshots are one of the best use cases. PNG screenshots with text and UI elements convert to WebP at 60-80% smaller sizes while keeping text perfectly crisp at high quality settings.
When should I keep PNG instead of WebP?
Keep PNG when the destination requires it — some older email clients, document editors, and print workflows only accept PNG. For anything displayed in a web browser, WebP is the better choice.
Does PNG to WebP conversion work for logos and icons?
Yes. Logos and icons with flat colors and transparency convert extremely well — expect 70%+ size reduction with no visible difference and full transparency support.

What Converts Best from PNG to WebP?
Screenshots: UI screenshots with text and flat areas compress 60–80% smaller in WebP while keeping text perfectly crisp — one of the best use cases for conversion.
Logos and icons: Flat-color graphics with transparency convert with 70%+ size reduction and full alpha-channel preservation. Your transparent backgrounds survive intact.
Graphics with gradients: Banners, illustrations, and charts often shrink dramatically because WebP's prediction-based compression handles smooth color transitions far better than PNG's.
When to Keep PNG
Keep the original PNG when your destination demands it: print workflows, some document editors, older email clients, and app stores that require PNG assets. For anything displayed in a web browser, WebP is strictly better — smaller files, same quality, same transparency.
Working with photos instead? Use the JPG to WebP converter, or the image compressor to reduce any image's file size.
