What is AVIF (AV1 Image File Format)?
AVIF delivers the smallest files of all common image formats at high quality.
Based on the AV1 video codec, AVIF can be half the size of a JPG at comparable quality. The price is slow encoding and still patchy support outside browsers.

Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device, and there is no upload.
Is there a file size limit?
There is no limit on our side, but your browser memory is. Images work for very large files; for videos, files above a few hundred megabytes can fail on devices with little memory.
Will the quality suffer?
That depends on the target format and settings. Use the quality option to balance size and detail; lossless targets keep everything the source contained.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Fast hardware paths are used where available, with a compatible fallback otherwise.
