WebP exists for one reason: the same picture, in far fewer bytes.
A typical JPG drops 25 to 35 percent and a PNG often drops 60 to 80 percent, with no visible difference at sensible quality. On an image-heavy page that is the single biggest speed win available.
Page speed is a ranking factor and images are usually the heaviest thing on a page. Swapping PNGs for WebP is the least-effort improvement to Core Web Vitals most sites can make.
The conversion runs in your browser using the canvas. Your images never reach a server, so there is nothing to store, leak or wait for.
No account, no install, nothing uploaded.
It sets the quality. Web and Blog is the right default for most pages.
Up to five at a time, mixed formats are fine.
Individually, or the whole batch as a single ZIP.
Almost always one of these.
One file or two hundred. No daily counter, no paid tier hiding behind it.
Fair question. Here's the honest version.
Pick a quality preset, drop up to five JPG, PNG, GIF or BMP files onto the page, and click Convert. Each one comes back as a WebP you can download individually or take as a ZIP. Nothing is uploaded and there is no account.
A JPG typically drops 25 to 35 percent. A PNG usually drops much more — 60 to 80 percent is common, because PNG is a lossless format carrying data WebP can encode far more efficiently. Screenshots and flat graphics see the biggest wins.
No — this page goes one way, into WebP. If you have a WebP you need as a JPG, the quickest route today is to open it in your browser, right-click and choose Save image as, then pick JPEG; on a Mac, Preview will export it too. We are looking at adding the reverse direction here.
At the Web and Blog preset most people cannot tell the difference side by side, and that is the point. If the image is a photograph you will be judged on, use the Photography preset — it keeps far more detail for a file that is still smaller than the original.
Yes, now. Chrome, Firefox, Edge and Safari have all supported it for years, as have iOS and Android. The old advice about keeping a JPG fallback is out of date for normal web use — the only place it still matters is very old software that was never updated.
Up to five at a time. Each one shows its own progress and size saving, and when the batch finishes you can download them all as a single ZIP rather than clicking through five downloads.
Yes. WebP supports transparency, so a PNG with a transparent background stays transparent — which is part of why PNG-to-WebP is such a large saving. You get the transparency without PNG's file size.
No. The conversion happens in your browser using the canvas, so the images never leave your device. Load the page, turn on Airplane Mode, and it still works.
Same rules on every one: free, no sign up, no watermark.
