Questions, answered
Will converting JPG to AVIF reduce quality?
A little, as with any re-save. JPG and AVIF both use lossy compression, so converting removes some fine detail. At the default quality it’s very hard to spot, and you can raise the quality for a near-identical result.
Will the AVIF be smaller than the JPG?
Usually, yes. AVIF compresses images more efficiently than JPG, so most files get noticeably smaller. You’ll see the exact size of every file, and how much you saved, as soon as it’s converted.
Can I convert lots of JPG files at once?
Yes. Add as many as you like: they’re converted side by side on your device, and you can download them one by one or all together as a .zip.
Do my images leave my device?
No. The JPG to AVIF conversion runs entirely in your browser, so your images are never sent anywhere. There’s no sign-up and no limit on how many you convert.
