Frequently asked questions

What is AVIF?

AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec. It offers the best compression available - typically 50% smaller than JPG at the same quality. It's supported by all modern browsers.

Why is conversion slower?

AVIF's superior compression comes from more complex encoding algorithms. Converting a typical iPhone photo takes 3-5 seconds. The file size savings (often 50%+ smaller than JPG) make the wait worthwhile.

Is AVIF widely supported?

Yes! AVIF is supported by Chrome, Firefox, Safari, and Edge. Some older apps may not support it yet, but browser support is excellent. For maximum compatibility, consider HEIC to JPG instead.

Are my photos uploaded anywhere?

No! All conversion happens directly in your browser using JavaScript and WebAssembly. Your photos never leave your device - they're never uploaded to any server.
