    Options

    One GIF up to 20 MiB, 30 seconds, 300 frames, 1920 px per side and 100 million decoded frame-pixels. Output max 1000 px per side. Re-encoding can change colors; a smaller palette does not guarantee a smaller file. Preserve disposal, transparency, loop count and quantized frame delays.

    Example and expected result

    A 640 × 400, 10-frame GIF resized to width 320 becomes 320 × 200. A 100 ms frame delay remains 100 ms; byte savings are measured, not promised.

    If it is not working

    • The animation exceeds 300 frames or the decoded-pixel budget. Use a shorter or smaller GIF.
