Convert JPG to WebP
WebP is the smaller, modern cousin of JPG — every current browser reads it, and at the same visual quality it typically shaves 25–35% off the file. If you're preparing images for a website, an app, or just want to save space without throwing away quality, converting JPG to WebP is an easy win. This tool decodes your JPG and re-encodes it as WebP entirely in your browser using the canvas encoder built into your browser — no uploads, no server, no watermarks, and it works offline. Drag the quality slider to balance size against fidelity: 80% is a good default for photos, drop lower for thumbnails or push toward 100% when detail matters. One honest note: JPG has no transparency, so a WebP made from JPG won't have an alpha channel either — if you need transparent WebP, start from a PNG instead. For maximum compatibility with ancient software, keep the original JPG.

Frequently asked questions
Are my JPG files uploaded?
No. Decoding and WebP encoding happen inside your browser tab via the built-in canvas encoder. Your images never leave your device, and it works offline.
How much smaller will the WebP be?
Typically 25–35% smaller than the JPG at visually matching quality. The exact gain depends on the image: detailed photos compress less dramatically than smooth gradients or screenshots.
Will converting to WebP make my images look worse?
At sensible quality settings the difference is hard to see. Lower the slider too far and you'll introduce softening and artifacts — preview and pick the point where size and quality balance for you.
Do all browsers support WebP?
Yes — Chrome, Firefox, Edge, and Safari (14+) all display WebP, so it's safe for the web today. Encoding WebP from canvas is likewise supported across modern browsers; very old Safari can't export it and this tool tells you plainly.
Is WebP better than JPG?
For web delivery, generally yes: smaller at equal quality. JPG still wins on oldest-software compatibility and is fine when you don't care about file weight.
Can I keep transparency?
Not from a JPG source — JPG has no alpha channel, so there's nothing to preserve. If you need transparent WebP, start from a PNG with our PNG to WebP tool.
