Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Convert PNG images to AVIF entirely in your browser — processed on your device, never uploaded. AVIF keeps transparency fully intact while compressing far tighter than PNG ever can, so logos, screenshots and UI graphics shrink dramatically without losing their see-through edges.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
Transparency kept, weight dropped
Like PNG to WebP, the alpha channel survives conversion untouched; unlike it, AVIF compresses the color underneath even tighter. Graphics routinely land 70–90% smaller than the source PNG with edges just as clean. For pixel-exact needs keep a PNG master and let Compress PNG shrink it losslessly instead.
Screenshots and sharp text
AVIF handles flat panels and gradients well, but very fine text at low quality can soften. Quality 80–90 keeps UI screenshots crisp; judge with the built-in compare view before batch-exporting a whole set.
Frequently asked questions
Is transparency preserved?
Yes — AVIF has a full alpha channel, so nothing is flattened. This is the key difference from converting to JPG, which paints transparent pixels white.
How much smaller than PNG?
Graphics and screenshots typically shrink 70–90%; photographic PNGs even more. PNG pays for lossless storage in bytes, and AVIF simply does not.
What happens to metadata?
AVIF output is written clean — any EXIF or text chunks in the PNG are stripped, which for published graphics is usually the safer default.
Is it private?
Yes. The conversion happens entirely on your device — the image is read, re-encoded and saved without ever touching a network. There is no server-side queue, no temporary copy in some bucket, nothing to expire or leak. Want proof? Run one file through, switch your connection off, and run another — it still works.
