// ABOUT QOI
QOI (Quite OK Image) is a modern lossless format designed for speed rather than maximum compression. It encodes and decodes 3–10x faster than PNG while producing files of comparable size. QOI is particularly valuable in developer toolchains, game asset pipelines, and real-time applications where CPU time is more important than file size.
// ABOUT PNG
PNG uses lossless compression with full alpha-channel transparency support. It preserves every pixel exactly, making it the standard choice for screenshots, logos, web graphics, and any image where precision matters. PNG files tend to be larger than lossy alternatives but guarantee no quality degradation.
// WHY CONVERT
Converting QOI to PNG is useful when you need your image in a format suited for web graphics, screenshots, logos, icons, digital art, and images requiring transparency. Both formats use lossless encoding, so the conversion preserves every pixel exactly — no quality is lost. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is QOI?
QOI is a lossless format designed for fast encode/decode in developer contexts. It has limited support outside of tooling ecosystems.
What is PNG?
PNG is a lossless format with universal compatibility across all platforms, browsers, and image editors.
Will converting QOI to PNG lose quality?
No. Both formats are lossless. Every pixel is preserved exactly in the PNG output.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
