Dropping frames keeps the same duration but makes motion choppier.
Lossy LZW (0–200). 30 is a balanced default; higher values shrink more but add noise.
About this GIF compressor
- • Start from a preset, then drag Scale, Frame rate, and Compression quality if you need more control.
- • Scale is usually the most effective. Dropping frames keeps the same duration but looks choppier. Higher lossy values shrink more but add noise.
- • 100% local browser processing — your GIF never leaves this device.
- • Free to use, no account, and no watermark on the download.
GIF compression can reduce colors or resolution. Stronger settings save more space but may add visible artifacts.
Need an exact file size?
Compress a GIF to a specific size such as 1MB, 2MB, 5MB, or 10MB.
Compress GIF to a specific sizeUse this free GIF compressor to compress animated GIF files and reduce file size in your browser. You control the compression level so you can trade a little quality for a much smaller GIF.
"The Graphics Interchange Format is a color raster image format that supports animated sequences of frames."— W3C GIF89a specification
- Compress GIF animations without installing software
- Reduce GIF file size with scale, frame-rate, and lossy sliders
- Keep animation timing while applying GIF compression
- Download the compressed GIF instantly
If you need a GIF under a specific limit such as 1MB or 5MB, use Compress GIF to a Specific Size instead of guessing the quality slider.
Compressing a GIF online takes three steps.
"GIF images are limited to an 8-bit palette of 256 colors per frame, which is why palette size has a large effect on file size."— MDN image format guide
- Upload your GIF. Drag and drop a GIF or click to choose a file. Decoding stays on your device.
- Choose a preset and options. Start with Lossless or Balanced, then drag Scale, Frame rate, and Compression quality if you need a smaller file.
- Preview and download the compressed GIF. Compare the original and compressed files, then download the smaller GIF.
Reset Settings restores Balanced without removing the uploaded GIF. Change GIF to start over with a new file.
Reduce GIF file size while preserving as much visual quality as possible. This page does not claim that every GIF can be compressed with zero quality loss.
- Resolution: more pixels mean more data in every frame
- Frame count and animation duration: longer clips are larger
- Number of colors: a full 256-color palette is usually heavier
- Frame complexity and motion: busy scenes compress less well
Lossless optimization keeps more detail. Maximum compression saves more space. Balanced is the default starting point for most animated GIFs.
GIF compression can shrink an animated GIF with lossless LZW optimization (duplicate frames, unchanged regions, transparent pixels) and lossy LZW, plus optional fewer colors, lower frame rate, and smaller size.
- Fewer palette colors reduce the unique values stored in each frame
- Duplicate-frame and transparency optimizations remove redundant pixels without changing the picture
- A smaller width and height cuts the number of pixels to encode
- Lower frame rate and lossy LZW pack the GIF more tightly
The compressor applies these steps locally in your browser and keeps each frame delay.
Frequently asked questions
Upload your GIF, pick a preset such as Lossless or Balanced, then select Compress GIF. You can also drag the Scale, Frame rate, and Compression quality sliders before compressing.
Yes. This tool is built for animated GIFs. Duplicate-frame and transparency optimizations keep the original duration. A lower frame-rate option drops frames on purpose and looks choppier.
The Lossless preset optimizes LZW without reducing colors: it merges duplicate frames, crops unchanged regions, and packs transparent pixels more tightly. Balanced adds light lossy LZW (about 30). Stronger presets add more lossy steps and can change the look.
Large GIFs usually have a high resolution, many frames, a long duration, lots of colors, or complex motion. Reducing colors, optimizing repeated frames, or slightly resizing the image can shrink the file.
Not by default. Frame delays are kept, so duration stays the same. If you choose Half or One third frame rate, motion looks choppier because frames are dropped.
No. GIF files are processed locally in your browser. Nothing is uploaded to OmniGIF servers.
