Compress AVIF images online.

AVIF is the next-generation image format based on the AV1 codec from the Alliance for Open Media — the same technology used by Netflix and YouTube. It delivers 30-50% better compression than WebP at equivalent quality.

With support for HDR, wide colour gamut, 10/12-bit depth, alpha transparency, and lossless compression, AVIF is the most feature-rich image format available. A 10 MB JPEG can often be reduced to 1-2 MB as AVIF with no visible quality difference.

Key features

  • 30-50% better compression than WebP
  • AV1 codec — same technology used by Netflix
  • HDR, wide colour gamut, 10/12-bit depth support
  • Full alpha channel transparency
  • Parallel encoding to offset slower AVIF compression

How to compress avif — step by step

  1. Drop your image: Drag and drop any image format — JPEG, PNG, WebP — onto the upload area.
  2. Adjust AVIF settings: Set quality (1-100) and speed preset. Slower speeds produce smaller files with better quality.
  3. Preview the result: Use the comparison slider to check detail retention, especially in shadows and highlights.
  4. Download your AVIF: Save individual AVIF files or download all as a ZIP. Nothing was ever uploaded.

Common use cases

Whether you are a photographer, web developer, e-commerce manager, or social media creator, optimizing images before publishing saves bandwidth, improves page load times, and ensures compatibility with platform-specific requirements. Our browser-based compressor works with all major image formats and processes everything locally for your browser with no uploads.

Frequently Asked Questions

  • Is AVIF better than WebP?

    AVIF typically achieves 30-50% better compression than WebP at the same quality level, especially for photographic content. It uses the AV1 codec from the Alliance for Open Media.

  • What browsers support AVIF?

    AVIF is supported by Chrome (85+), Firefox (93+), Safari (16.1+), and Edge (121+). Coverage is over 92% of global browser usage.

  • Does AVIF support transparency?

    Yes. AVIF supports full alpha channel transparency, HDR (PQ and HLG), wide colour gamut (P3, Rec.2020), 10-bit and 12-bit depth, and lossless compression.

  • Is AVIF good for photography?

    AVIF excels at photography. The AV1 codec handles gradients, textures, and fine detail much more efficiently than JPEG or WebP. A 10 MB JPEG can often be reduced to 1-2 MB as AVIF.

  • Can I batch compress images to AVIF?

    Yes. Drop any supported image format and set the output to AVIF. The queue processes files in parallel. AVIF encoding is slower than JPEG or WebP, so parallel processing helps maintain throughput.
