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.

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

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.

Limitations

JPG ↔ WebP Converter depends on what your browser can decode (HEIC, SVG, animated GIF, etc.). Output quality and colour profile may shift slightly compared with desktop Photoshop.
