Supports animated GIF89a and static GIF87a files up to 50 MB
Tip: You can also paste directly from clipboard (Ctrl + V)
🔒 100% In-Browser Privacy: Your GIF is decoded, quantized, and compressed locally in your browser. Zero bytes or animation frames are uploaded to any server.
How Online GIF Compression Works
How adaptive palette quantization, delta frame trimming, and LZW encoding reduce GIF file size.
Reduces color gradations to 128, 64, or 32 colors using Median-Cut clustering, producing longer matching byte sequences that LZW compresses significantly tighter.
Identifies static background areas across sequential frames and encodes only the modified bounding box rectangle, saving immense amounts of pixel data.
Selectively removes redundant duplicate frames while calculating accumulated millisecond delays so the resulting animation maintains exact real-world playback speed.
How to Compress a GIF in 4 Easy Steps
Follow these 4 simple steps to optimize your animated or static GIF files.
Drag & drop or choose your animated or static GIF89a image from your device.
Select Balanced (128 colors), Small File (64 colors + 50% fps), or custom dimensions.
Our in-browser engine optimizes palettes, trims delta frames, and re-encodes LZW streams in seconds.

GIF Optimization vs. Quality
Understanding the difference between palette reduction, frame decimation, and dimensions.
Palette Optimization: GIF files are limited to 256 colors per frame. Reducing the palette from 256 to 128 colors reduces file size by 30% to 50% with virtually imperceptible visual loss.
Frame Optimization: In animated GIFs with high frame rates (e.g. 30 fps), dropping every second frame cuts the file size in half while delay aggregation keeps the animation playing at original speed. For static images, visit our dedicated Image Compressor.
Frequently Asked Questions
Everything you need to know about compressing GIF animations online.
Upload your GIF image, review its original dimensions and frame count, select your preferred compression preset (Balanced, Small File, or Best Quality), adjust color or resize settings if desired, click 'Compress GIF', and download your smaller GIF in seconds.
Yes. Our GIF compressor fully decodes and preserves every frame in the animated sequence, including loop counters, frame delay timings, and transparency.
Yes. The generated output is a genuine animated GIF89a file that plays and loops automatically in all web browsers, chat applications, and image viewers.
By default, all frames are preserved. You can optionally choose to reduce frame rate (dropping every 2nd or 3rd frame) which aggregates delays to cut file size in half while maintaining natural animation speed.
Yes. You can scale the GIF to 75%, 50%, or enter custom pixel widths and heights with aspect ratio lock enabled.
Yes. You can choose from 256, 128, 64, 32, or 16 color palettes using adaptive Median-Cut color quantization to drastically reduce LZW compressed file size.
Color reduction and frame decimation reduce file size with subtle visual differences. At 128 colors, the difference is virtually imperceptible for most animations.
If an uploaded GIF was already aggressively compressed with a 16-color palette and you re-encode it with 256 colors, the file size may increase. Our tool reports real results truthfully without fake stats.
Yes. The tool runs on all modern mobile web browsers across iOS, Android, and tablets without requiring app downloads.
No. Your GIF is processed directly in your browser. No files or animation frames are uploaded to any server or external service.
Yes. GIF transparency is fully supported and preserved across all animation frames.
Yes. Under the Frame Rate dropdown, choose 'Drop Every 2nd Frame' or 'Keep 1 in 3 Frames' to significantly drop file size while automatically adjusting frame delay.
The Balanced preset (128 colors, Delta Bounding Box enabled, 100% resolution) offers the ideal balance of crisp visual quality and 40% to 70% file size savings.
Typical compression savings range from 30% to 80% depending on the original dimensions, color depth, and frame complexity.
This tool performs genuine binary GIF frame decoding, palette re-quantization, bounding box trimming, and LZW re-encoding. Zero simulated compression.
