Supported formats and limitations
Accepts JPG or JPEG, up to 20 files at a time.
- Very old browsers and some older software don't support opening WebP files — check your target platform before relying on it exclusively.

Frequently asked questions
WebP typically produces a smaller file than JPG at a similar visual quality, which helps with page load speed and storage space. Every current major browser supports displaying WebP.
Modern browsers all support WebP, but some older software and a few niche tools don't. If universal compatibility matters more than file size, keep a JPG copy too.
Once conversion finishes, each image's row shows the original and converted size side by side.
No. Conversion happens entirely in your browser using the Canvas API — nothing is sent to a server.
90% (the default) is a safe starting point. Lower it for smaller files if a slight quality reduction is acceptable for your use case.
