Will my JPG images look different after converting to AVIF?▼
At the same visual quality, AVIF is typically much smaller than the JPG source. Start around quality 60–80 in the slider for photos and compare the result before publishing.
What to Know Before You Convert
Convert to AVIF to cut image file size for a website or app — typically the biggest win when JPGs are the largest assets slowing down a page.
No transparency to worry about
JPG never had an alpha channel, so this conversion is purely a size/quality trade-off, not a transparency question.
Different artifacts, not just "worse"
At matched visual quality AVIF files are typically much smaller than the JPG original. Compression artifacts look different (blockiness vs. blur) rather than simply worse — compare the result before publishing.
