Browser processing — files never leave your device

Convert PNG graphics to WebP while keeping transparency. WebP usually stores the same image in a fraction of the PNG's size.

About this tool

Unlike JPG, WebP supports an alpha channel, so logos, icons and UI screenshots with transparent backgrounds convert cleanly. For graphics with large flat areas the size reduction over PNG is often dramatic. The quality setting applies lossy WebP compression; at 90%+ the result is visually indistinguishable for most graphics while still much smaller than the PNG.

Frequently asked questions

Is transparency preserved?
Yes. WebP supports full alpha transparency, so transparent PNG areas stay transparent after conversion.
Why is WebP so much smaller than my PNG?
PNG compression is lossless and relatively simple. WebP can apply modern lossy compression even to graphics with transparency, which shrinks files substantially with little visible change.
Should I use WebP or PNG for my website?
Use WebP for anything served to browsers — it is smaller and universally supported. Keep PNG for editing masters or when a workflow specifically requires it.
