Convert GIF images to AVIF in a browser-only batch. Files and results are never uploaded.

Common output settings

Advanced settings

Use lossless encoding when supported

The batch workspace is ready. Image encoding becomes available after the verified browser engine is loaded.

GIF decode → normalized image frames → AVIF encode

GIF input preserves frame order, frame delays, looping, and simple transparency when available.

AVIF output favors small files and supports alpha and animation, but encoding can take longer.
