Frequently asked questions
Does AVIF support transparency like PNG?
Yes. AVIF supports full alpha-channel transparency. You can convert a PNG with a transparent background to AVIF and the transparency will be preserved.
How much smaller will my PNG be after converting to AVIF?
For photographic PNGs, AVIF can achieve 60–80% reduction compared to the PNG file size. For PNGs with flat colors and sharp edges (logos, screenshots), results are more modest since AVIF's lossy compression introduces visible artifacts on hard edges.
Should I convert logos and icons from PNG to AVIF?
With caution. AVIF uses lossy compression which can blur sharp edges and text. For logos and icons with flat colors, lossless WebP or PNG remain better choices. AVIF excels with photographic content, not graphics.
Are my files uploaded to a server?
No. All conversion happens in your browser using the Canvas API. Your PNG files never leave your device.
