How this Free GIF Compressor — Reduce GIF File Size Online works
This compression tool reduces animated GIF file sizes by regenerating the color palette with fewer colors using FFmpeg WebAssembly. The core technique applies the palettegen filter with a configurable max_colors parameter (32, 64, 128, or 256) combined with stats_mode=diff, which analyzes inter-frame differences to build an optimized palette. The paletteuse filter then re-quantizes each frame using Bayer dithering at scale 5 for smooth gradient handling.
Two additional compression levers are available: dimensional scaling reduces the GIF width and height proportionally (50% or 75% of original), and frame rate reduction drops redundant frames to lower the total frame count. These three controls—color reduction, dimension scaling, and FPS adjustment—work together to achieve compression ratios of 30% to 80% depending on the source material.
The interface displays real-time compression statistics including original size, compressed size, percentage reduction, and bytes saved. A preview panel shows the compressed GIF alongside the original for visual comparison. The entire pipeline executes in the browser via WebAssembly, meaning no image data leaves the user's device. This tool is particularly useful for meeting platform file size limits on Discord, Slack, and email attachments.
