Convert QOI (a tiny, blazing-fast lossless format loved by game developers) to PNG — PNG opens everywhere, while QOI has limited support, and the conversion can preserve every pixel, and transparency carries over. Drop files below: decoding and encoding run entirely in your browser via WebAssembly, so images are never uploaded to a server.

Will converting QOI to PNG lose quality?+
No. PNG is lossless: every pixel of the decoded QOI is preserved exactly.
Is there a file size or count limit?+
No hard limits and no accounts — processing uses your own device's memory and CPU, so very large images are only constrained by your browser (multi-hundred-megapixel images may fail on low-memory devices). Batch as many files as you like; they are processed in sequence.
Can I convert PNG back to QOI?+
Yes — use the PNG to QOI converter, or just change the output format dropdown after dropping files.
