Landscape illustration encoded with higher JPEG quality
Higher quality sample. Inspect the roof edges and smooth sky.
Same landscape with stronger JPEG compression and visible edge artifacts
Lower quality sample at identical dimensions. A smaller byte count can discard visible detail.

Understanding gif compressor

GIF compression reduces animation size through frame, dimension and palette choices.

Check timing and motion after removing frames, and inspect gradients after reducing colors.

A practical workflow

  1. Choose the required source files, if any. Files are handled as stated in the workspace privacy label.
  2. Set the available controls and apply the operation.
  3. Compare the actual output, check its dimensions and download the generated file.

Decisions and limitations

  • Output width (pixels)
  • Output height (pixels)
  • Palette colors

Up to 500 frames, 4 megapixels per frame and 40 million decoded frame pixels in total. GIF delays are rounded to 10 ms with a 20 ms minimum; color reduction is lossy.
