Why convert JPG to AVIF?
AVIF is the most efficient image format supported by modern browsers — files come out roughly half the size of an equivalent JPG at the same visible quality.
Quality and transparency
Encoding AVIF takes a few seconds longer than other formats — that is normal. All modern browsers display AVIF; very old software may not.
Frequently asked questions
Can I convert several JPG files at once?
Yes — drop as many files as you want and download them individually or as a single ZIP.
Can I convert AVIF back to JPG?
Yes. The tool accepts JPG, PNG, WebP and AVIF as input, and you can pick any of them as the output format.
Is my photo uploaded anywhere?
No. Everything runs locally in your browser with WebAssembly — your image never leaves your device, which makes this safe even for ID photos and documents.
