Frequently Asked Questions
Why convert JPG to AVIF?
AVIF compresses photos more efficiently than JPG, so you get a noticeably smaller file at similar visual quality. This is useful for faster websites and saving space.
Will the photo look worse?
AVIF is saved with a quality setting, like JPG. At this setting most people cannot tell the difference, while the file is much smaller.
Which browsers can create AVIF here?
Encoding runs in your browser, so you need Chrome 100 or newer, or Edge 100 or newer. If your browser cannot encode AVIF, the tool tells you instead of saving a wrong file.
Is my photo uploaded anywhere?
No. Everything runs in your browser, so the photo never leaves your computer and the tool works offline.
Does it keep the same dimensions?
Yes. The width and height in pixels stay the same; only the format and file size change.
Does AVIF support transparency?
Yes, but a JPG has no transparency to begin with, so the AVIF will simply have a solid image like the original.
How much smaller will the file be?
Often quite a lot smaller than the JPG at the same quality. The tool shows the exact before and after sizes so you can compare.
Does it work on a phone?
Yes, on a recent Chrome or Edge mobile browser, with nothing to install.
