BMP
BMP is an uncompressed 24-bit Windows bitmap format. Files are large but pixel-perfect and trivial for any image library to read.
QOI
QOI (Quite OK Image) is a lossless format that decodes 20-50× faster than PNG. Great for engines and tools that need to stream lots of images at runtime.
Why convert BMP to QOI.

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