Why put WEBP on your site
WEBP was designed for the web, and it shows: at matching visual quality it typically lands 25–35% below a JPG and far below a photographic PNG. Lighter images mean faster first paint, better Largest Contentful Paint scores and less bandwidth on every visit. Unlike JPG it also carries an alpha channel, so a logo or a cut-out product shot keeps its transparent edges in a single, small file.
How to convert an image to WEBP
- 1Drop a JPG or PNG into the box above.
- 2Set the quality — 80% is the default and works well for photos.
- 3Click Convert to WEBP and compare the before and after previews.
- 4Check how much you saved, then download the WEBP.
Transparency is preserved
Converting a transparent PNG to JPG forces a solid background colour behind it. WEBP has no such limitation: the alpha channel is carried straight through, and the preview shows a checkerboard so you can confirm the transparent areas survived. That makes WEBP a genuine drop-in replacement for PNG logos, icons and overlays — usually at a fraction of the size.
Quality, and when to raise it
Conversion is lossy, which is where the savings come from. Photographs hold up remarkably well at 75–85%. Screenshots, diagrams and anything with small text or hard edges deserve 90% or more, since lossy compression is hardest on sharp boundaries. Input files up to 20 MB are accepted; the before/after sizes are shown after every conversion so you can dial the slider in with real numbers rather than guessing.
Frequently asked questions
›Does converting to WEBP keep PNG transparency?
Yes. WEBP supports an alpha channel, so transparent pixels stay transparent — no white or coloured background is inserted. The result preview sits on a checkerboard so you can see it for yourself.
›How much smaller will my file be?
Photos usually shrink 25–35% compared with a JPG of similar quality, and a photographic PNG can drop by far more. Flat graphics with few colours sometimes barely change, or even grow — the tool tells you either way before you download.
›Can every browser display WEBP?
Yes, in practice. Chrome, Edge, Firefox and Opera have supported it for years, and Safari has since version 14 in 2020. Only genuinely obsolete browsers such as Internet Explorer can't render it.
›Are my images uploaded to a server?
No. Decoding and encoding both happen in your browser using the canvas API, so the image never leaves your device. It also means there are no queues, no accounts and no file retention to worry about.
›It says my browser can't create WEBP — what now?
A few older browsers can display WEBP but not encode it, so the tool checks before converting rather than silently handing you a PNG. Opening the page in a current version of Chrome, Edge or Firefox resolves it.
