// ABOUT GIF
GIF is a legacy format dating to 1987 that supports animation and simple binary transparency. It is limited to a palette of 256 colours per frame, which means photographic content will undergo colour quantisation. Despite its age, GIF remains ubiquitous for short animations and reaction images across messaging platforms and social media.
// 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.
// WHY CONVERT
Converting GIF to QOI is useful when you need your image in a format suited for game asset pipelines, real-time texture streaming, build tools, developer workflows, and any context where encode/decode speed is critical. 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 GIF?
GIF is a legacy format with a 256-colour palette supporting animation.
What is QOI?
QOI is a lossless format optimised for encode/decode speed, useful in performance-sensitive developer pipelines.
Will converting GIF to QOI lose quality?
No. QOI is lossless and represents all pixel data from the decoded GIF exactly. The 256-colour limit of the GIF source is preserved but no new quality loss occurs.
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.
