Convert JPG, PNG, HEIC, SVG and other images to WebP, usually much smaller than JPEG or PNG at similar quality, so pages load faster. Transparency is kept, and everything runs in your browser with nothing uploaded.

Set the Quality; around 80 suits photos, 90 keeps text and edges crisp.
Optionally cap the Max width / height or pick a Target file size.

Frequently asked questions
Why convert images to WebP?
WebP files are usually much smaller than JPEG or PNG at similar quality, which makes pages load faster. Every current browser can display them.
Does WebP support transparency?
Yes. Transparent PNGs stay transparent when converted here.
Can I convert PNG or JPG to WebP in bulk?
Yes. Drop many files at once and download them together as a .zip.
Can I convert an animated GIF to WebP?
Only as a still image. Animated GIFs keep just their first frame, and the converter tells you when that happens.
Does it work on iPhone and Safari?
Yes. Browsers that can't save WebP themselves, such as Safari, use a built-in WebP encoder instead, so the conversion works in every current browser. It can be slower on large images.
Is WebP good for SEO?
Smaller images load faster, which helps page speed. To support very old browsers too, serve WebP with a JPEG fallback using the HTML picture element.
Are my images uploaded?
No. Conversion runs in your browser.

When not to use WebP
Upload forms and older apps that accept only JPG or PNG; use PNG to JPG or keep the original.
Files you will keep editing: every lossy save loses a little more detail.
Animations: this converter saves still images only.
If you need the smallest file and can wait longer, try Image to AVIF. To go back, use WebP to JPG.
