GIF Compressor
Upload a GIF, choose compression strength, frame sampling, color count, and an optional target size, then export a smaller animation.

What compression changes
Compression can reduce the palette, skip frames, and merge identical neighbors according to the selected settings.
Compare the output size with the preview and motion. A target size is a best-effort limit, not a promise.

Method and calculation
Compression combines palette reduction, optional frame sampling, and removal of identical neighboring frames; the encoder then writes a new GIF.
Boundaries and limitations
Stronger settings can reduce color detail or motion smoothness. Very complex GIFs may not reach a requested target size.
Privacy and local processing
Reading, decoding, palette work, frame processing, and result generation happen in this browser. Files are not uploaded or saved.
Format and standards
The output uses the GIF89a structure. Different players may display short delays, color quantization, and finite loops differently.
GIF compression questions
What does the compression preset change?
It combines palette reduction, optional frame sampling, and merging identical neighboring frames. Stronger settings can make colors or motion less smooth.
Can the target size be guaranteed?
No. The tool tries progressively stronger candidates, but a complex animation may still remain above the requested size.
