JPEG XL
JPEG XL (JXL) is a modern royalty-free format with both lossy and lossless modes. It often beats AVIF and WebP on quality at the same file size, with much faster encoding.
AVIF
AVIF is the newest open image format. It delivers smaller files than WebP at the same quality — often 30-50% smaller than JPG. Supported by all modern browsers.
Why convert JPEG XL to AVIF.

Q.01How do I convert JPEG XL to AVIF?+
Drop your JPEG XL file onto the converter above (or click to pick one), then hit Convert. Your AVIF download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.
Q.02Is converting JPEG XL to AVIF lossless?+
No. AVIF uses lossy compression by default. You can tune the quality slider to trade file size for fidelity. Quality 90 is a good default that beats most online tools.
Q.03Will my JPEG XL files be uploaded to a server?+
No. Pixelmint runs the entire conversion in your browser using the Canvas API. Your image bytes never touch our servers, which is why this is safe for confidential screenshots, IDs, and proprietary artwork.
Q.04Is there a file size limit?+
There's no hard limit, but very large images (over ~50 megapixels) can be slow on low-RAM devices because everything happens locally. Most browsers cap canvas size around 32,767 pixels per side.
Q.05Does it cost anything?+
No. JPEG XL to AVIF conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
