Q.01How do I convert QOI to JPEG XL?+
Drop your QOI file onto the converter above (or click to pick one), then hit Convert. Your JPEG XL download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.
Q.02Is converting QOI to JPEG XL lossless?+
No. JPEG XL 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 QOI 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. QOI to JPEG XL conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
