Why use animated AVIF over GIF?

Much Smaller File Sizes

Animated AVIF files are typically 50-90% smaller than equivalent GIF files, thanks to the modern AV1 codec compression. This means faster page loads and lower bandwidth costs.

Superior Image Quality

Unlike GIF which is limited to 256 colors, AVIF supports millions of colors with 10-bit and 12-bit depth, plus alpha transparency and HDR — producing smooth gradients and photo-realistic animations.

How it works

  1. Upload: Drag and drop your video file (MP4, WebM, MOV, MKV) into the upload area.
  2. Configure: Set the start and end time, output frame rate, width, and compression quality.
  3. Convert: Click the "Convert to AVIF" button. The tool extracts frames using FFmpeg WASM and encodes them into an animated AVIF — all locally in your browser.
  4. Download: Preview and save the resulting animated AVIF file.
