GIF compressor

Reduce animated GIF dimensions, colors and frames while preserving the selected duration.

Compress an animated GIF

Reduce dimensions, colors or frame count and compare the GIF copies. Processing runs in a browser worker; files are not uploaded.

Choose a GIF or load the example.

Previews may start at different times. Check the downloaded animation, colors and transparency in the viewer you will use.

How to use

Choose a GIF, inspect its dimensions, frame count and duration, and start with the balanced preset.
Optionally resize by percentage or one dimension, select colors and frame interval, or trim using inclusive frame numbers starting at 1. Skipped frame delays are added to the frame kept at the start of each group.
Compare the actual output bytes and animation, then download the result separately from the original. A target size is a check, not an automatic search or guaranteed upload approval.

The example has 6 frames at 100 ms each. Keeping every 2nd frame produces 3 frames at 200 ms each: the duration remains 0.6 seconds.

Color reduction, resizing and frame removal can change appearance. GIF supports only fully transparent or fully opaque pixels. One palette entry is reserved for transparency; the selected total includes that entry. Comments and application metadata are omitted except the repeat setting. No fixed reduction percentage is promised.
