JPG ↔ WebP Converter — free online tool

Move between JPEG and WebP in either direction when optimising a media library or recovering compatibility with older tools.

When to use JPG ↔ WebP Converter

Reduce JPEG gallery weight with WebP, or convert WebP back for tools that only accept JPEG.

Good for email attachments, CMS uploads, and faster page loads without installing desktop software.

What JPG ↔ WebP Converter does not do

Only still photos between JPEG and WebP. No animation, no CMYK, no PDF pages.

How to use JPG ↔ WebP Converter

Add a JPEG or WebP file—the JPG ↔ WebP Converter picks the conversion direction.
Adjust quality if exporting to WebP for web performance.
Process the image in-browser.
Download and compare file size against your original JPEG.

Practical tips

Going JPEG → WebP shrinks library size; WebP → JPEG restores compatibility with older tools.
Each lossy re-encode loses a little detail, so convert from the best source you have.
Spot-check faces and gradients after conversion, where artefacts show up first.

Example

Convert a JPEG gallery image to WebP, or WebP back to JPEG for a printer.
