WebP delivers the same visual quality as PNG at 25–35% smaller file sizes. For web pages, smaller images mean faster load times and better Core Web Vitals scores — a ranking factor Google weighs directly. Switching hero images and UI assets from PNG to WebP typically shaves hundreds of kilobytes off a single page without any perceptible quality loss.
Unlike JPEG, WebP fully supports transparency (alpha channel), so it's a direct replacement for PNG wherever you need a transparent background. Logos, icons, product shots with cutouts — all can move to WebP and keep their transparency intact while becoming noticeably lighter.
This converter runs entirely inside your browser using the Canvas API. Your images are never uploaded to any server — they're processed locally and stay on your device. That matters for confidential documents, personal photos, or any situation where you'd rather not hand files to a third party.
Frequently asked questions
Yes. WebP supports full alpha-channel transparency, so it's a direct drop-in for PNG wherever a transparent background is required. You won't lose cutouts, logos with transparent areas, or any other alpha data during conversion.
By default this tool uses lossy WebP at 85% quality, which is visually indistinguishable from lossless for most images while cutting file size by 25–40%. If you need pixel-perfect output, raise the quality slider to 100 — at that point the converter produces near-lossless WebP.
All major modern browsers support WebP natively: Chrome (since 2011), Firefox (since 2019), Edge, and Safari (since version 14, released 2020). WebP is safe to use for any audience on a modern device.
No. Everything happens locally in your browser using the Canvas API. Your images are never sent to any server, stored anywhere, or shared with third parties. You can even use this tool offline after the page has loaded.
