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.
JPG
JPG (JPEG) is a lossy raster format with excellent compression for photographs. It does not support transparency, so transparent pixels become white.
Why convert QOI to JPG.
JPG is the most universally supported format for photographs and social uploads. Converting your QOI files to JPG dramatically reduces file size — often by 5-10× — making them faster to share, attach to emails, or upload to platforms that reject QOI.

Q.01How do I convert QOI to JPG?+
Drop your QOI file onto the converter above (or click to pick one), then hit Convert. Your JPG download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.
Q.02Is converting QOI to JPG lossless?+
No. JPG 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 JPG conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
Q.06Why is the transparent background white in my JPG?+
JPG doesn't support transparency. Any transparent pixels are flattened against a background color (white by default — you can change it in the settings panel above before converting).
