Re-optimise AVIF with AV1 encoding tuning. Strip bloated profiles. Process entirely in your browser - no server ever involved.
Drag & drop or click to browse (AVIF)
AVIF is the most efficient image format available in 2026 - typically 50% smaller than JPG and 20% smaller than WebP at the same visual quality.
But 'most efficient format' does not mean 'always optimally compressed.' AVIF files exported from design tools often carry bloated colour profiles, suboptimal AV1 encoding settings, and unnecessary metadata.
FastCompressor re-encodes AVIF with tuned AV1 parameters and strips non-essential data.
Most tools that export AVIF - browsers, Squoosh, ImageMagick - use conservative AV1 encoding presets for speed.
Those aren't optimal for file size.
FastCompressor uses content-adaptive presets tuned for quality-per-byte efficiency.
AVIF supports HDR and P3 wide colour gamut, which means exported files often include large embedded colour profiles (ICCv2 / ICCv4).
When you're delivering sRGB web images, these profiles are wasted bytes.
FastCompressor strips them.
AV1 encoding is CPU-heavy.
FastCompressor uses hardware acceleration where available (Apple Silicon Neural Engine, discrete GPU encoding) to make AVIF batch compression practical at scale.
AVIF is increasingly used for sensitive commercial content - product renders, unreleased designs.
FastCompressor never sends your files to a server.
Built for professionals who need speed, privacy, and quality.

AVIF: The format winning the web - and still undercompressed
AVIF (AV1 Image File Format) achieved 95% browser support in 2025, crossing the threshold that makes it viable for production web use. It genuinely outperforms WebP - especially on photographic content, gradients, and HDR imagery. Netflix uses AVIF for thumbnails. Google serves AVIF where supported. Apple added full AVIF support in Safari 16.
But there's a catch: AVIF is computationally expensive to encode. Most export tools default to conservative quality settings to keep encoding times manageable. The result is AVIF files that are larger than they need to be - sometimes by 20-40%.
FastCompressor's browser tool re-encodes AVIF files using optimised encoder settings. For most photographic content, you'll see another 20-35% reduction from an already-exported AVIF. For graphics and UI assets, the gain is smaller but still meaningful.
For Cloudinary and Imgix users: If you're auto-converting images via CDN, your AVIF quality setting matters. FastCompressor lets you manually fine-tune quality to find the exact byte budget sweet spot before deploying.
The tradeoff to know: AVIF encoding is slow compared to WebP or JPG - even on a fast machine. For single files, this is imperceptible. For batches of 500+ AVIF files, use the desktop app with hardware acceleration enabled.
