How to convert an image to WebP
- Drag your PNG or JPG images onto the box above, or click to browse. You can add several at once.
- Adjust the quality slider if you like — 85 is visually lossless, and the new file size updates live as you drag.
- Click Download on any image, or Download all to save every WebP.
Why convert to WebP?
Speed. WebP is a modern image format that stores the same picture in far fewer bytes — typically 25–35% smaller than JPG or PNG at the same visual quality. On a website that adds up fast: pages load quicker, visitors on phones burn less data, and Google's Core Web Vitals reward the faster load, which can help your search rankings. If you run a site, a store, or a blog, switching images to WebP is one of the easiest performance wins available.
Broad support. WebP is no longer the risky new format it once was. Every current browser — Chrome, Edge, Firefox, and Safari, on both desktop and mobile — displays it natively, and the major content platforms accept it. For everyday web use you can rely on it working for your audience.
How much smaller is WebP?
It depends on the image, but the savings are consistently large. Detailed photographs usually shrink 25–35% versus a comparable JPG, and flat graphics or screenshots can drop even more compared with PNG. The size readout next to each file shows exactly what you saved, so you can nudge the quality slider until the size and look are both where you want them.
Does WebP keep transparency?
Yes. Unlike JPG, WebP supports an alpha channel, so a PNG with a transparent background keeps that transparency after conversion — you get PNG-style see-through areas at a fraction of the file size. This tool encodes each image on a transparent canvas, so nothing gets filled in behind your graphic. That makes WebP a great replacement for heavy transparent PNGs like logos and product cutouts.
Is it private and safe?
Yes. Unlike most online converters, Toolyard does all the work inside your browser using your own device. Your images are never uploaded to any server, so nothing can be stored, seen, or leaked. You can even use it offline once the page has loaded.
Frequently asked questions
Is WebP supported everywhere?
Every modern browser — Chrome, Edge, Firefox, Safari and their mobile versions — displays WebP, and all major social and web platforms accept it. Only very old software or a handful of legacy desktop apps may not open it, in which case JPG or PNG is the safer choice.
Does WebP keep transparency?
Yes. WebP supports an alpha channel just like PNG, so a transparent PNG stays transparent after conversion. This tool encodes on a transparent canvas, so see-through areas are preserved.
Will I lose quality converting to WebP?
Quality is adjustable. At the default setting of around 85 the result is visually lossless — almost impossible to tell from the original — while the file is much smaller. Lower the slider for smaller files, or raise it toward 100 to keep maximum detail.
Why are WebP files smaller?
WebP uses more advanced compression than JPG or PNG, so it stores the same picture in fewer bytes — typically 25–35% smaller at matching quality. Smaller images mean faster page loads and less bandwidth.
Are my images private, and can I convert several at once?
Yes to both. Everything runs inside your browser on your own device, so images are never uploaded and stay completely private. Drop as many files as you like — the quality setting applies to all of them, and Download all saves every WebP.
