Frequently Asked Questions
Are my images uploaded to a server?
No. The HEIC → AVIF conversion runs entirely in your browser using your device's own processor. Your files never leave your computer or phone, and nothing is stored on our servers.
Why convert HEIC to AVIF?
AVIF is best for next-generation compression with the smallest files. Converting from HEIC lets you take a HEIC file and get those benefits without any desktop software.
Can I convert several images at once?
Yes. Drop or select multiple files and they're processed in a queue, then downloaded individually or all together as a ZIP.
Will I lose quality?
AVIF is a lossy format, so you can trade a little detail for a smaller file using the quality slider. Set it to 90–100% to keep the result visually identical to the original.
My browser can't create AVIF — why?
AVIF encoding is currently supported in Chrome and Edge. On Safari or Firefox the tool will let you know and you can use WebP instead, which offers similar savings with universal support.
