Convert PNG to AVIF
Convert PNG images to AVIF for dramatically smaller files while keeping transparency. Free, private, no upload.
Why Convert PNG to AVIF?
AVIF supports transparency like PNG, but compresses far more efficiently — often 80-90% smaller than PNG for graphics and screenshots. Conversion runs entirely in your browser via WebAssembly; nothing is uploaded.
Does it keep transparency?
Yes — AVIF supports an alpha channel, so transparent areas in your PNG stay transparent in the converted file.
Have a JPEG instead? Try converting JPG to AVIF, or go back with AVIF to JPG.
Frequently asked questions
Why convert PNG to AVIF?
AVIF keeps PNG’s transparency but compresses far more efficiently — often 80-90% smaller for graphics, logos, and screenshots.
Does it keep transparency?
Yes — AVIF supports an alpha channel, so transparent areas in your PNG stay transparent.
Is AVIF better than WebP for PNG graphics?
AVIF usually compresses further than WebP at the same quality, though WebP has marginally broader software support. Both beat PNG by a wide margin.
Is it private?
Yes — everything runs locally in your browser with no uploads.
Will a screenshot look sharp as AVIF?
Yes, at a reasonable quality setting — AVIF handles flat graphics and sharp edges well, similar to how PNG and WebP do.
Why is AVIF slower to convert than WebP?
AV1 encoding is more computationally intensive than WebP’s, which is the tradeoff for AVIF’s smaller file size — this only affects conversion time, not viewing.
When should I keep the PNG instead?
Only for guaranteed compatibility with very old software, or workflows that specifically require PNG. For the web, AVIF or WebP are almost always smaller with no visible difference.
Can I convert several PNGs to AVIF at once?
Yes — drop multiple images and download them together once converted.
