Convert an image to WebP

WebP is the pragmatic default for images on the web: smaller than JPG for most photographs, and it keeps transparency like PNG.

What you typically save

For a typical photograph, WebP at quality 0.8 lands noticeably below a JPG of comparable visual quality. Savings are largest for detailed photos and smallest for images that were already heavily compressed — re-encoding an already-crushed JPG mostly just adds a second generation of artefacts.

When to keep the original format

Keep JPG when the file is going somewhere outside a browser — some desktop software, print workflows and email clients still don't handle WebP. Keep PNG when you need pixel-exact lossless graphics.

FAQ

Frequently asked questions

Is WebP better than JPG?
For web delivery, usually — smaller files at similar quality plus transparency support. For compatibility outside browsers, JPG is still the safer choice.
Does WebP support transparency?
Yes, WebP has an alpha channel, so it can replace PNG for logos and cut-outs while producing smaller files.
How do I open a WebP file?
Any modern browser opens it directly. If a program refuses it, convert it back to JPG or PNG with the format converter.
Are my images uploaded to a server?
No. Every step — decoding, cropping, resizing and encoding — runs in your browser using the Canvas API. The image file never leaves your device, so nothing is stored or transmitted by us.
