0 = slowest / best compression · 10 = fastest / larger file. Default 6 balances speed and size.
Controls color resolution. 4:2:0 reduces color data by 75% — great for photos. 4:4:4 keeps full color — use for graphics, text, or sharp edges.
Higher bit depth reduces banding in gradients. 10-bit often compresses better than 8-bit. 12-bit is rarely needed.

What is AVIF?
AVIF (AV1 Image File Format) is a next-generation image format developed by the Alliance for Open Media — the same group behind the AV1 video codec. Built on the highly efficient AV1 intra-frame coding, AVIF delivers 30–50% better compression than JPEG and roughly 20% better than WebP at equivalent visual quality. It supports transparency (alpha channel), HDR with 10- and 12-bit color depth, and wide color gamut. Major platforms including Google, Netflix, and Facebook already serve billions of AVIF images daily. Learn more about choosing the best image format for web.
Why Convert Images to AVIF?
When you convert image to AVIF, you unlock the smallest file sizes available for web images today. A 500 KB JPEG can shrink to 200–250 KB in AVIF with no visible quality loss — that means faster page loads, lower bandwidth bills, and better Core Web Vitals scores (LCP, CLS) which directly impact your Google search ranking. Our tool lets you convert unlimited images for free, entirely in your browser via WebAssembly — no files are uploaded to any server. Check out our guide on how to reduce image file size for more optimization tips.
When to Use AVIF?
Use AVIF for hero banners, product photography, blog thumbnails, portfolio galleries, and social media assets. It excels with photographic content where lossy compression at quality 50–70 produces visually identical results at a fraction of the original size. For specific workflows, try our dedicated JPG to AVIF converter or PNG to AVIF converter for streamlined single-format conversion.
Browser & Platform Support
AVIF is natively supported in Chrome 85+, Firefox 93+, Edge 121+, Opera 71+, and Safari 16.4+, covering over 96% of global web users. For the remaining browsers, you can implement a <picture> fallback with WebP or JPEG. On the server side, CDN providers like Cloudflare, Fastly, and AWS CloudFront offer automatic AVIF delivery via content negotiation.
Frequently Asked Questions
What is AVIF format?▸
AVIF (AV1 Image File Format) is a next-generation image format developed by the Alliance for Open Media. It delivers significantly better compression than JPEG, PNG, and WebP while maintaining excellent visual quality. Our converter runs entirely in your browser via WebAssembly for complete privacy.
Which browsers support AVIF?▸
AVIF is supported by Chrome, Firefox, Edge, Opera, and Safari (since version 16). Combined, this covers about 96% of web users. Our tool uses a WebAssembly encoder that works in all modern browsers, and processing happens entirely client-side.
How does AVIF quality compare to JPEG?▸
AVIF typically produces files 30-50% smaller than JPEG at the same perceived quality. At quality 50-70, AVIF images look comparable to JPEG quality 80-90 but at a fraction of the file size. All conversion is done locally in your browser for privacy.
Does AVIF support lossless compression?▸
Yes, AVIF supports both lossy and lossless compression modes. At quality 100, the conversion is essentially lossless. For web use, quality 50-70 provides an excellent balance of size and visual quality. Processing is handled entirely client-side via WebAssembly.
How much smaller are AVIF files?▸
AVIF files are typically 30-50% smaller than equivalent JPEG files and about 20-30% smaller than WebP. This means faster page loads and lower bandwidth costs. The conversion runs in your browser using WebAssembly, so your images never leave your device.
What do the Advanced Settings control?▸
Advanced Settings let you fine-tune the AVIF encoder. Speed/Effort controls encoding time vs compression ratio (0 = slowest/best, 10 = fastest). Chroma Subsampling (4:2:0, 4:2:2, 4:4:4) controls color data resolution. Bit Depth (8, 10, 12-bit) affects gradient smoothness and HDR support. All processing runs locally via WebAssembly.
What is Chroma Subsampling in AVIF?▸
Chroma subsampling reduces color data to shrink file size. 4:2:0 keeps 25% of color info — ideal for photos. 4:2:2 keeps 50% — good balance. 4:4:4 keeps 100% — best for graphics, text overlays, and sharp color edges. Most photos look identical at 4:2:0, saving 20-30% more space.
