About image to webp
WebP is the format to use when the destination is a website. It compresses roughly 25 to 35 percent smaller than JPEG at the same visual quality, and substantially smaller than PNG for graphics, while supporting transparency and animation. For a site with many images that difference is the single cheapest performance improvement available, and it shows up directly in Core Web Vitals scores.
Browser support stopped being a concern some time ago. Chrome, Edge, Firefox, Safari, and every current mobile browser handle WebP. The remaining gaps are outside the browser: some older desktop software, some email clients, and a scattering of upload forms that check file extensions against a list written a decade ago. That is the practical rule — WebP for the web, JPEG or PNG for anything that has to survive being emailed or opened in unpredictable software.
The tool offers both lossy and lossless modes because WebP genuinely does both, unlike JPEG. Lossy with a quality setting is right for photographs and is where the size savings are dramatic. Lossless is right for logos, icons, and screenshots, where it typically beats PNG by around a quarter with no quality difference at all. Picking the wrong mode is the usual reason people conclude WebP was not worth it.
Encoding runs on the canvas in your browser, which means the conversion is bounded by your device rather than a queue. It also means nothing is uploaded — worth noting because bulk image conversion for a website is exactly the kind of task people hand to an online service without thinking about it, sometimes including client work under NDA.
Typical size against other formats
| Content | Versus JPEG | Versus PNG |
|---|---|---|
| Photographs (lossy mode) | 25–35% smaller | Far smaller |
| Logos and icons (lossless) | Not comparable | ~26% smaller |
| Screenshots (lossless) | Sharper and smaller | 20–30% smaller |
| Images with transparency | JPEG cannot | ~25% smaller |
Image to WebP FAQ
Is WebP supported everywhere?
In browsers, effectively yes — Chrome, Edge, Firefox, and Safari all support it. Outside browsers there are gaps in older desktop software and some email clients, so use JPEG or PNG for files that will be emailed.
Should I use lossy or lossless WebP?
Lossy for photographs, where the size savings are large. Lossless for logos, icons, and screenshots, where it still beats PNG by around a quarter.
How much smaller will my files get?
Typically 25 to 35 percent smaller than an equivalent-quality JPEG, and around 26 percent smaller than PNG for graphics in lossless mode.
Does WebP support transparency?
Yes, in both lossy and lossless modes — one of its main advantages over JPEG.
Will converting to WebP help my site speed?
Usually yes, and noticeably if the site is image-heavy. Image weight is the most common cause of slow page loads.
Are my images uploaded?
No. Encoding happens on the canvas in this browser tab.
