Frequently Asked Questions
AVIF (AV1 Image File Format) is a cutting-edge image format based on the AV1 video codec, developed by the Alliance for Open Media which includes Google, Apple, Microsoft, Netflix, and Mozilla. AVIF delivers dramatically better compression than JPEG and WebP, producing files that are typically 50% smaller than JPEG and 20% smaller than WebP at equivalent visual quality. It supports both lossy and lossless compression, HDR (high dynamic range), wide color gamut (WCG), and full alpha transparency.
AVIF enjoys approximately 89% global browser support as of 2025. All major browsers now support it: Chrome (since version 85), Firefox (since version 93), Edge (since version 85), Opera, and Samsung Internet. Safari added AVIF support in Safari 16, covering macOS Ventura and iOS 16+. For the remaining ~11% of browsers, we recommend using the HTML picture element to serve an AVIF source with a WebP or JPEG fallback to ensure universal compatibility.
SharpWebP defaults to lossless or near-lossless AVIF encoding. In lossless mode, every pixel is preserved exactly -- zero quality loss, guaranteed. In near-lossless mode, quality reduction is mathematically imperceptible (SSIM scores above 0.99) while achieving 50-80% file size reduction compared to JPEG. Every AVIF conversion is validated with PSNR and SSIM quality metrics before download, so you always know exactly what quality level you are receiving.
AVIF offers about 20% better compression than WebP at the same visual quality, plus support for HDR and wide color gamut that WebP lacks. However, WebP has broader browser support (97% versus 89%) and significantly faster encoding and decoding speeds. For maximum compatibility, serve WebP. For maximum compression and image quality, serve AVIF. For the best of both worlds, use a picture element with AVIF as the primary source and WebP as the fallback.
Yes, SharpWebP's AVIF converter is completely free with no watermarks, no quality restrictions, and no hidden fees. Free users can convert up to 5 images per day. Paid plans (starting at 499 INR/month) unlock batch AVIF conversion, higher daily limits, and priority server processing. AVIF output is available on all plans, provided the server supports AVIF encoding -- SharpWebP automatically detects capabilities and falls back to WebP if AVIF is unavailable.
