Accepts JPG, PNG, GIF - Max 20 MB
75 to 85 percent is recommended for web delivery
JPG on the left, WEBP on the right
The same photo at the same quality, saved both ways. Drag the handle: they look identical, but the WEBP is the smaller file.
JPG 213 KB
WEBP 176 KB
Here WEBP came out about 17 percent smaller, because this source was already a compressed JPG. On a clean original, Google's 25 to 34 percent figure is closer to what you will see. Either way the screen image is the same.
What you actually gain
Smaller files
25 to 34 percent under JPG at the same quality, which is the single biggest lever for page weight.
Better Core Web Vitals
Lighter images load sooner, which directly helps Largest Contentful Paint, a Google ranking signal.
One format, both jobs
WEBP does small photos like JPG and transparency like PNG, so it can replace either on the web.
Before you switch everything to WEBP
Support is effectively universal
Every current browser reads WEBP, over 95 percent of users. For ancient browsers, keep a JPG fallback in a picture element.
Use it on the web, not for handoff
WEBP is for serving images. If you are emailing a file to someone on old desktop software, JPG is the safer choice.
This tool only converts to WEBP
To go from WEBP back to JPG or PNG, run it through the Image Compressor and pick the output format there.
When to reach for it
Speeding up a site
Convert your heaviest hero and gallery images to WEBP to cut page weight and pass PageSpeed.
Replacing big PNGs
Swap transparent PNGs for WEBP to keep the cut-out edges at a much smaller size.
WordPress media
Upload WEBP straight into the media library for lighter posts without a plugin.
Frequently asked questions
Google measures lossy WEBP at 25 to 34 percent smaller than JPG at the same visual quality, and lossless WEBP about 26 percent smaller than PNG. The exact gap depends on the image: a photo that is already heavily compressed will save less than a clean original.
No. At quality 80 and above the two are indistinguishable on screen. The difference is only in file size.
Yes, in practice. Chrome, Firefox, Edge, Opera and Safari 14+ all read WEBP, which is over 95 percent of browsers. For very old browsers, serve a JPG fallback with the HTML picture element.
Yes, a full alpha channel like PNG, so it can replace a transparent PNG at a smaller size.
Yes. WordPress 5.8 and later accept WEBP in the media library and serve it like any other image.
