Next-Gen AVIF, Unbeatable Savings.
AVIF Is the Future of Web Images. FastCompressor Makes It Smaller Still.
Re-optimise AVIF with AV1 encoding tuning. Strip bloated profiles. Process entirely in your browser - no server ever involved.

AVIF is the next-generation image format that offers significantly better compression than WebP and JPEG. Deliver incredible quality at ultra-low file sizes.
Why AVIF Needs Additional Compression
Default Encoders Use Conservative Settings
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.
HDR and Wide-Gamut Metadata
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.
AVIF Is Still Slow to Encode
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.
Privacy First, Always
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.
- Web developers adopting AVIF in image delivery pipelines via elements
- Shopify and Squarespace stores where the platform serves AVIF to supported browsers
- Designers exporting reference imagery from Figma or Photoshop in AVIF format
- CDN engineers optimising image origin files before distribution
- Performance engineers hitting 90+ Lighthouse scores on image-heavy landing pages
Why use FastCompressor Desktop for next-gen avif, unbeatable savings.?
Online tools are great for quick, single-image edits. But when you need to process hundreds of files or maintain strict privacy, native software is the only way to go.
Deep Dive
Learn how it works
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.
