how to convert png to avif
Drop your PNG file
Drag your PNG file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs Canvas API on your device to decode the Portable Network Graphics and encode it as AV1 Image File Format. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the AVIF file
When the conversion finishes, the AVIF file is ready to download. Save it anywhere on your device.
FAQ
common questions
Does AVIF preserve PNG's transparency?
Yes — AVIF carries a full alpha channel, the same as PNG. Transparent UI graphics, logos, illustrations, stickers, and any PNG with semi-transparent edges convert cleanly without flattening. The transparency comes through pixel-perfect.
How much smaller will the AVIF be than the PNG?
Typically 50–70% smaller in lossy mode, and meaningfully smaller even in lossless mode. PNG is uncompressed-style (every pixel stored exactly); AVIF uses modern compression that crushes photographic content while preserving sharp edges well. A 4 MB PNG screenshot commonly becomes a 600–800 KB AVIF.
Will sharp edges (text, line art, icons) survive AVIF compression?
Generally yes at default quality. AVIF handles high-contrast edges better than older lossy formats like JPG — it doesn't produce the same fringing around text. For pixel-perfect screenshots or icon sprites where any softening would be visible, use AVIF's lossless mode (still produces smaller files than PNG) rather than the default lossy.
Does AVIF work in every browser yet?
All current Chrome, Firefox, Safari, and Edge versions decode AVIF natively — around 94% of modern web traffic. Older browsers, some in-app webviews, and many native desktop apps still can't open AVIF. For website use, serve AVIF with a PNG fallback via the <picture> element; for arbitrary distribution (email attachments, asset hand-offs), PNG is still the safer choice.
Why is AVIF encoding so slow compared to other image conversions?
AVIF uses the AV1 codec, which prioritises compression efficiency over speed. The encoder explores many candidate representations per image block to find the smallest one that still looks right — that exploration takes time. Expect a few seconds per image, longer for very high-resolution sources. The good news: the encode is a one-time cost; serving AVIF at runtime is fast.
