GIF vs QOI: Format Comparison
Key differences between the two formats
| Feature | GIF | QOI |
|---|---|---|
| Compression | LZW lossless (palette-based) | Lossless full-color encoding |
| Color depth | 256 colors (8-bit palette) | Full 24-bit RGB or 32-bit RGBA |
| Animation | Supported (multiple frames) | Not supported (single frame) |
| Transparency | 1-bit (on/off per pixel) | Full 8-bit alpha transparency |
| File size | Small for simple graphics | Larger — uncompressed-ish |
| Encoding speed | Moderate | Very fast — simple algorithm |
| Best for | Simple animations and icons | Game assets and real-time textures |
When to Convert
Common scenarios where this conversion is useful
Extract a still frame for game use
Convert a GIF to QOI to extract a single still frame in a fast lossless format. Game engines load QOI significantly faster than PNG during runtime asset loading.
Upgrade icon palette to full color
GIF is limited to 256 colors, causing banding on gradient icons. Converting to QOI stores the full-color decoded pixel data with no palette restriction.
Real-time UI asset pipeline
Applications that load UI assets at runtime benefit from QOI's fast decode path. Convert GIF sprites to QOI so your renderer spends less time decompressing images.
Intermediate format in processing pipelines
When running multiple image processing steps, use QOI as an intermediate format. It preserves full quality from the GIF decode while being faster to read/write than PNG.

Frequently Asked Questions
QOI (Quite OK Image) is a lossless image format designed for speed. Its simple encoding algorithm makes it faster to decode than PNG while still preserving every pixel perfectly.
QOI supports full 24-bit color unlike GIF's 256-color limit, and decodes much faster than PNG. It is ideal for game textures and real-time applications where loading speed matters.
No. QOI is a single-frame format. The converter captures the first frame of the GIF as a still image. If you need animated output, consider WebP or APNG instead.
Usually yes. GIF uses palette compression that is very efficient for simple graphics. QOI stores full-color pixel data, so it will typically be larger — but it preserves far more color information.
No. Everything happens in your browser using the Canvas API. Your GIF file never leaves your device, so there is no privacy risk and no waiting for an upload.
Yes. QOI supports both RGB and RGBA (with full alpha transparency). The GIF's 1-bit transparency will be preserved as an alpha channel in the QOI output.
QOI support is available in many tools including GIMP, ImageMagick, and various game engines. Libraries exist for all major programming languages. Browser support is not native — a JS library or backend is needed.
No server-side limit because conversion is local. The practical limit is your browser's available memory — most browsers handle images up to 4000x4000 or larger without issues.
The converter processes one file at a time. Since conversion is instant in the browser, you can quickly process multiple GIFs back-to-back without waiting.
QOI is popular in game development, embedded systems, and real-time rendering. Its simple format is easy to implement and its fast decode path benefits applications that load many images at runtime.
