AVIF descends from AV1 — the video codec built by Google, Netflix, and Amazon to replace everything before it. On still images, AVIF runs half the bytes of JPG at matching visual quality.

100% private. Nothing is uploaded.
Drop JPG, PNG, HEIC, WebP, or TIFF. The converter accepts 8-bit and 10-bit sources where supported.
Pixels run through the AV1 encoder in intra-only mode (single frame). Quality 50 — the Google-recommended match to WebP quality 80.
Files typically 30–50% smaller than matched JPG, 15–25% smaller than matched WebP. Alpha preserved, ICC profile embedded.

AVIF trails WebP by a couple points on browser support but leads on compression. On high-traffic endpoints, the saved bytes add up fast.

Encoding speed, browser support, compression ratios, and when AVIF is worth it.
Typically 15–25% smaller on the same content at matched SSIM. On photographic images with fine detail, savings trend higher. On flat graphics with large solid color areas, savings trend lower. Measure on your actual asset mix.
AV1 is computationally expensive — it's a video codec doing complex block prediction and variable transforms. In-browser encoding runs 1–3 seconds per image at default settings. Server-side tooling with multi-core libaom is faster for production.
Chrome 85+ (2020), Firefox 93+ (2021), Safari 16.4+ (2023), Edge 121+ (2024). About 92% global coverage. For the remaining 8%, use picture with WebP or JPG fallback.
Yes — identical to WebP and PNG. Alpha channel encodes separately using AV1's monochrome mode and combines at decode. Transparent PNG inputs convert to transparent AVIF with no visual change.
Technically yes, but 8% of users (mostly older Safari, some enterprise browsers) would see broken images. Recommended approach: picture with AVIF first, WebP fallback, JPG as last resort. Modern CMS and CDN tools automate this.
Not yet. WebP has 5% more browser coverage and encodes 10× faster. For sites prioritizing compatibility and encoding speed, WebP remains the default. AVIF makes sense when every saved byte matters and encoding happens once at build time.
