JPG to WebP

Make a WebP from a JPEG.

About this tool

WebP is the format many CDNs and modern browsers prefer for photographs because it often beats JPEG at the same visual quality. This page encodes a JPEG as WebP in the browser so you can drop it into a site that already serves WebP.

Old Internet Explorer and some email clients will not show WebP. If the destination is a printer or a stubborn form, keep JPEG. This conversion does not restore detail the JPEG already lost.

The JPEG is decoded locally and encoded as WebP by the browser. Quality is a WebP setting, not a second JPEG pass in another app. 50 MB and 32 megapixels apply.

How to convert JPG to WebP

  1. Choose a JPEG. It stays on your device.
  2. Adjust WebP quality if you need a smaller file.
  3. Convert and download the WebP.

50 MB / 32 MP. If this browser cannot encode WebP, the tool fails in the tab rather than shipping the photo out. Animation is not created from a still JPEG.

FAQ

Does the JPEG leave the device?
No. Encoding is local. We do not host the WebP for you.
Will WebP always be smaller?
Usually for photos, not always for already-tiny JPEGs. Check the byte count on the result.
Is this lossless?
No. Both JPEG and typical WebP here are lossy. PNG to WebP is the path that can keep alpha.
Can Safari open the result?
Current Safari can. Very old browsers cannot. That is a client limit, not an upload issue.
Should I compress first?
No need. This encoder already has a quality control. Compress image would make another JPEG, which is a different job.
