Frequently Asked Questions
What is AVIF format?
AVIF (AV1 Image File Format) is a next-generation image format that offers significantly better compression than JPEG, PNG, and even WebP. It is based on the AV1 video codec.
Does my browser support AVIF encoding?
AVIF encoding support in browsers is currently limited. Chrome 85+ and some Chromium-based browsers support it. Firefox and Safari can display AVIF images but currently cannot encode them. The tool automatically detects your browser's capabilities.
What happens if my browser doesn't support AVIF encoding?
The tool will show a clear notice and you can select an alternative output format (WebP or PNG) that your browser does support.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device.
How much smaller are AVIF files compared to JPEG?
AVIF typically achieves 50% or greater file size reduction compared to JPEG at similar perceptual quality, and about 20-30% better compression than WebP.
