AVIF delivers the best compression efficiency of any mainstream image format, producing files 20 to 50% smaller than WebP and up to 90% smaller than JPEG at equivalent visual quality. Built on the AV1 video codec, AVIF supports HDR, wide color gamuts, and alpha transparency, making it the top choice for performance-obsessed developers and publishers targeting modern browsers. As adoption grows across Chrome, Firefox, Safari, and Edge, AVIF is shifting from experimental to essential.
However, AVIF files exported at default quality settings from conversion tools are not always optimally encoded. A second compression pass with tuned parameters can extract additional savings, critical when serving image-heavy pages where every kilobyte affects LCP and CDN costs. Our AVIF compressor re-encodes with efficiency-focused settings while preserving the visual fidelity that makes AVIF worthwhile over older formats.
All processing occurs in your browser. Your AVIF assets are never uploaded to a server, making this safe for pre-production staging, client deliverables, and proprietary media libraries. Batch compress entire directories and deploy optimized files to your CDN.

Drop AVIF files from your conversion pipeline, static site build, or CDN origin. Supports files up to 50 MB with batch upload for site-wide optimization.
Adjust quality to hit your performance targets. AVIF maintains excellent fidelity at lower quality settings than JPEG, so you can be more aggressive.
Download compressed images individually or as a ZIP. Swap them on your server using <picture> fallbacks for older browsers.
Pick your use case for AVIF. These are starting points from real production workflows, not generic defaults.

Automated AVIF conversion pipelines often default to high quality settings that prioritize safety over efficiency. In performance-critical deployments, news sites publishing hundreds of images daily, ecommerce platforms with large catalogs, and image CDNs serving millions of requests, an extra 20% reduction per file compounds into meaningful bandwidth and cost savings. Manual compression tuning captures savings that generic converters leave on the table.
AVIF also comes with browser support caveats that make right-sized files even more important. When you must serve JPEG or WebP fallbacks for older browsers, the AVIF version needs to be significantly smaller to justify the encoding complexity. Aggressively optimized AVIF that is 50% smaller than your WebP fallback makes the multi-format strategy worthwhile; marginally smaller AVIF does not.
Format specific guidance you will not find on generic upload tools.
Based on AV1 video coding, AVIF beats WebP and JPEG on byte size for most photographic content at equivalent quality.
iOS 16+ and macOS Ventura+ decode AVIF. Older Apple devices need WebP or JPEG in your picture stack.
Rather than hand rolling fallbacks, many CDNs serve AVIF to capable browsers automatically from one upload.
Browser encoding is slower than JPEG. Pre generate AVIF at build time for large catalogs; use this tool for batches and spot fixes.
AVIF already leads all formats in size, our optimizer pushes files even smaller for CDN and performance gains.
Compression maintains AVIF's advanced color capabilities for high-quality photography and media sites.
Compress AVIF images with transparency for UI graphics and product cutouts at a fraction of PNG size.
Ideal for publishers and developers who need every byte counted in Core Web Vitals optimization.

AVIF is typically 50% smaller than JPEG and 20 to 30% smaller than WebP at equivalent visual quality. Actual savings depend on image content and quality settings.
Chrome, Firefox, Safari, and Edge all support AVIF. Coverage exceeds 92% globally, but always provide JPEG or WebP fallbacks for full compatibility.
AVIF supports both modes. Lossy AVIF is recommended for photographs; lossless AVIF suits graphics needing transparency and pixel-perfect quality.
Use AVIF as the preferred format with WebP and JPEG fallbacks via <picture>. This gives modern browsers the smallest files while maintaining compatibility.
AVIF handles color differently and may appear slightly sharper or more saturated. Adjust quality settings and compare on target displays before deploying.
Yes. Upload multiple AVIF files, compress them together, and download all optimized images in a single ZIP archive.
AVIF encoding is more CPU-intensive than JPEG, but our browser based tool handles individual and batch files efficiently for typical web workflows.
