How to open AVIF files
Current major browsers; older applications vary. When a browser or application cannot decode the file directly, convert a copy to JPG for compatibility or PNG when transparency and lossless graphics matter.
When to use AVIF
- High-efficiency web images
- Modern responsive sites
- Reducing transfer size
Best settings for AVIF
- Use AVIF for modern web performance when small transfer size is more important than the fastest encoding workflow.
- Test fine text, gradients, skin tones, and transparent edges after conversion because AVIF settings can change visible detail.
- Keep WebP or JPG fallbacks when your publishing stack or audience includes older software.
Compatibility checklist
- AVIF support is strong in current browsers but less consistent in older applications.
- Browser AVIF encoding availability can vary, so conversion support depends on the device and browser.
- Animated or multi-image AVIF files should be handled with a dedicated animation workflow.
Limits to consider
- Encoding can be slower
- Legacy software support is less consistent than JPG or PNG
Convert AVIF images
Choose an output based on the destination, not just file size. Conversion runs locally in your browser whenever the required decoder is available.
