Examples
Results vary by image.
Transparent graphics
WebP keeps transparency, so it can replace PNG for icons and cutouts on the web.
Screenshots
Lossless WebP can be smaller than PNG for flat interfaces — but not always. We show the exact change.
Questions
Lossy or lossless?
Lossy for photos and most web images. Lossless for graphics that must stay pixel-exact, like interface screenshots.
Is transparency kept?
Yes, in both modes. A PNG with transparent areas becomes a WebP with transparent areas.
Why is my WebP larger than the original?
It can happen with small or heavily compressed images, or in lossless mode. We flag it so you can keep the original.
Are my images uploaded?
No. Everything runs in your browser; images are never uploaded.
