WebP is an image format built for the web. It stores photos and graphics in less space than JPG or PNG at the same visible quality, and every current browser displays it. Converting your site's images to WebP is one of the simplest ways to make pages load faster.
How much smaller is WebP?
It depends on the image. Photos usually come out noticeably smaller than the equivalent JPG at the same visual quality. Graphics and screenshots that were stored as PNG often shrink a great deal, because WebP can compress them lossily or losslessly. Try a few of your own images and compare; the difference varies from file to file.
Which quality setting?
WebP works like JPG here: a quality setting from 1 to 100 trades size for detail. The default of 85 is a safe choice for photos; 75 to 80 saves more with little visible difference. For logos and screenshots with sharp edges, go higher, around 90 to 95, to avoid soft edges. Transparency is kept, so a PNG logo on a transparent background stays transparent.
Will WebP work everywhere?
In web browsers, yes: Chrome, Firefox, Safari and Edge all display it. Outside the browser, support is good but not universal. Some older image editors, email clients and upload forms still reject WebP. Keep your originals, and send JPG when you are not sure what the recipient will use.
Is it private?
On this page the conversion runs in your browser with the libwebp encoder. Your images are never uploaded, so the files never leave your device. Free, no account, no daily cap, up to 50 MB per image.
Converting a whole site?
That is what the pipeline builder is for, and the Web images preset does it in one go: resize to 1600 pixels, convert to WebP and strip metadata across a whole folder. You can try a pipeline on up to 3 files for free; larger runs use Pro or credits and are processed on our server.
How to convert images to WebP
- Drop your JPG or PNG images onto the drop zone.
- Keep WebP as the output format and set the quality, or keep 85.
- Click Convert.
- Download the WebP files.
FAQ
Does converting to WebP keep my photo's location data?
Metadata is not reliably carried over. Add Strip Metadata in the same pipeline to be sure it is gone.
How do I use WebP on my website with a JPG fallback?
Use the HTML picture element with a WebP source and a JPG img inside it. Browsers pick the first format they support.
Can I convert WebP back to JPG or PNG?
Yes, with Convert Image.
Does WebP support animation?
The format does, but this tool converts still images only.
