WebP vs JPG: Differences and How to Choose
WebP is over a decade old and browser support is near-universal, yet 'downloaded a WebP and can't open it' remains a top search. Here's the real gap between WebP and JPG — and when converting to JPG is still worth it.
The technical differences
WebP comes in lossy (VP8) and lossless modes, plus alpha transparency and animation; JPG has only one lossy mode. At equal quality WebP is 25–35% smaller than JPG, and transparency plus animation are capabilities JPG simply doesn't have.
Compatibility today
Chrome, Edge, Firefox and Safari all decode WebP — inside a browser there's no issue. The friction lives outside the browser: older OS image viewers, some upload systems, and chat-app previews still occasionally reject it.
When to keep WebP
Image assets for your own website, mini program or CMS: the size advantage converts directly into load speed, and delivery happens entirely in-browser with zero compatibility concerns. For web assets, WebP is today's best default.
When to convert to JPG
The moment an image leaves the browser: sending to people, uploading to systems that only accept JPG, handing off to print or design software. Use this site's WebP-to-JPG tool — drop in, batch convert with quality and size options, all processed locally.
