What Convert JPG to WebP can do

How to use

Choose a JPG and it converts to WebP straight away, with the quality slider at 92%, where the change is hard to see on most photos. The line under the result shows both file sizes before you download. If the WebP came out bigger, move the slider down and it converts again.

Smaller for camera photos, not always for web images

A photo straight from a camera is saved at high quality, and as WebP it usually comes out about a quarter smaller. A JPG that was already compressed hard, as images saved from websites often are, can come out the same size or larger at 92%. Each lossy re-encode also costs a little detail, so keep the original.

Serve the WebP, keep the JPG

Every current browser decodes WebP, so it is a straight win for page weight on a website. It is not a drop-in replacement everywhere else: some upload forms, older photo software and print services still expect .jpg, and a few email clients will not render WebP inline. Keep the original for those and use the WebP where you control the page.

Limitations

Safari and the browsers on iPhone and iPad cannot create WebP. There, use Chrome, Edge or Firefox on a computer or an Android phone. Large photos may take longer on weaker devices.

Questions

Why is my WebP bigger than the JPG?

The JPG was probably compressed hard already, as images saved from websites often are, and at 92% the WebP spends bytes copying it closely. Move the slider down to about 80% and it converts again; if it is still bigger, keep the JPG.

Can I convert a page full of photos in one go?

Yes, right here: up to 30 JPGs convert to WebP in one run and are downloaded as one ZIP, with the filenames preserved so you can swap them into a page without renaming anything.

Which formats are supported?

This page converts JPG to WebP. Other pairs (JPG, PNG, WebP, AVIF, HEIC, SVG) each have their own tool, gathered in the related tools on this page.
