Converts to .avif — stays on your device
Why convert PNG to AVIF?
- Shrinking transparent logo and icon assets in a Figma → production pipeline on Next.js or Astro.
- Migrating design-system sprite sheets from PNG to AVIF for modern apps where the alpha channel matters.
- Cutting PNG screenshot weight on documentation sites (Docusaurus, VitePress, Nextra) without losing fidelity.
- Delivering smaller transparent product cut-outs on Shopify or Webflow PDPs where Lighthouse flags PNG weight.
- Optimizing hero illustrations for marketing pages that need crisp edges and a tiny payload.
- Replacing legacy PNG assets in mobile app bundles where AVIF is now natively supported.
How our converter works
The PNG is decoded and re-encoded as AVIF using your browser's built-in AV1 image encoder. Transparency survives the round trip — AVIF supports a full alpha channel, just like PNG. Because everything happens in your browser tab, it's safe for unreleased brand assets, client brand kits under NDA, and design-system updates you haven't shipped yet.
PNG vs AVIF — what's the difference?
| Feature | PNG | AVIF |
|---|---|---|
| Compression | Lossless only | Lossy or lossless (much smaller either way) |
| File size | Baseline | Commonly 50–80% smaller |
| Transparency | Full alpha | Full alpha — preserved |
| Color depth | 8-bit per channel | Up to 12-bit (HDR-ready) |
| Best for | Universal compatibility | Modern web, mobile, design systems |
Frequently asked questions
How much smaller will the AVIF be?
For photographic PNGs: commonly 70–80% smaller. For flat UI graphics and logos: 40–60% smaller. Even lossless AVIF usually beats PNG by 20–40%.
Does the AVIF preserve PNG transparency?
Yes. Both formats support an 8-bit alpha channel, and soft edges carry across cleanly.
Lossy or lossless AVIF?
Our default is lossy at 90% quality — typically invisible and gives the biggest size win. For UI graphics where banding would show, drop to a lossless encoder on a local tool; most web use cases don't need it.
Will my design tools open the AVIF?
Photoshop 2023+, recent Figma, and Affinity Photo handle AVIF. Older versions need plug-ins. For editing workflows, keep the PNG as the master and export AVIF only for delivery.
Is AVIF safe for production sites?
Yes. Every major browser released since 2022 supports it. For older browsers, serve PNG as a fallback using the <picture> element — most CDN image pipelines do this automatically.
Does batch conversion work?
Yes. Drop or select many PNGs; they convert sequentially. For batches over three files, the output is offered as a ZIP download.
About the PNG format
PNG has served the web since the late 1990s as the go-to format for anything with sharp edges, flat colors, or transparency — reliable, lossless, universally supported. AVIF is PNG's modern counterpart: a format designed from scratch for the bandwidth realities of the 2020s. It keeps PNG's alpha channel and lossless option, adds lossy encoding for a dramatic size win on photographic PNGs, and supports HDR and wide color. For sites already targeting modern browsers and shipping a PNG fallback, AVIF is often the single highest-leverage performance change available.
