Convert PNG to AVIF

Free, private, and instant — your files never leave your device.

AVIF is the most efficient widely-supported image format today — derived from the AV1 video codec, it typically produces files 50% smaller than JPEG and 20–30% smaller than WebP at equivalent visual quality, with full alpha-channel transparency and HDR support. Converting PNG to AVIF is one of the highest-impact optimizations for modern web delivery: PNG files are lossless and often very large for photographic content, and AVIF dramatically reduces that footprint without visible quality loss at high settings. Transparency is fully preserved. Note that AVIF encoding is computationally intensive; your browser runs the encoder in WebAssembly, so conversion takes a few seconds longer than WebP or JPEG.

How to Use

  1. 1

    Drop your PNG — the output is already set to AVIF. The converter uses a WebAssembly AVIF encoder that runs entirely in your browser.

  2. 2

    Adjust the quality slider. 70–80% is a good balance for web delivery; use 85%+ for images requiring close fidelity.

  3. 3

    Click "Convert to AVIF" — encoding runs locally via WebAssembly. Expect a few extra seconds compared to WebP or JPEG.

  4. 4

    Download the AVIF. Requires Chrome 85+, Firefox 93+, or Safari 16+ to display.

Frequently Asked Questions

Is AVIF supported in all browsers?

AVIF is supported in Chrome 85+ (2020), Firefox 93+ (2021), and Safari 16+ (2022). As of 2025, this covers well over 95% of browsers in active use. For older Safari or legacy browsers, serve AVIF with a WebP or JPEG fallback using the HTML <picture> element.

Why does AVIF encoding take longer than WebP or JPEG?

AVIF is derived from the AV1 video codec, which uses far more sophisticated compression algorithms than WebP or JPEG. Your browser runs the AV1 encoder in WebAssembly — efficient but still slower than the browser's native canvas encoder used for WebP and JPEG.

Does AVIF preserve transparency?

Yes. AVIF supports full alpha-channel transparency, just like PNG and WebP. Transparent pixels in the PNG remain transparent in the AVIF output.

Should I use AVIF or WebP for my website?

AVIF produces smaller files at the same quality — it's the better choice if your audience is on modern browsers (2020+). For maximum compatibility, use AVIF as the primary source with a WebP or JPEG fallback inside a <picture> element. For logos and flat-color graphics, WebP or PNG may compress just as well.
