# Convert PNG to AVIF.

> PNG to AVIF with transparency kept — converted locally.

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.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Transparency kept, weight dropped

Like [PNG to WebP](https://compress-pro.com/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](https://compress-pro.com/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.
