Compress GIF

Make animated GIFs smaller while keeping the animation and transparency. Pick a preset or fine-tune the colors, size and frame rate, compress several GIFs at once, and download them one by one or as a ZIP.

GIF compressor

Animated GIFs get big quickly: every frame is stored in full, in at most 256 colors, with a compression method from the 1980s. This tool rewrites your GIF more efficiently without changing the file type, so it still plays everywhere a GIF does. It shares one color palette across the whole animation, stores only what changed between frames, and lets you trade a little quality for a much smaller file by reducing colors, shrinking the picture or dropping frames.

Start with the Balanced preset. If the result is still too large, switch to Strong or adjust the settings one at a time, and check the preview of each result before downloading. To shrink other image types, see Compress WebP, Compress PNG and Compress JPG.

How to compress a GIF

1Add your GIFsDrag and drop them onto the box, or click it to choose files. Each file is checked to make sure it really is a GIF.
2Choose a preset or adjust the settingsLight keeps as much quality as possible, Balanced is the recommended starting point, and Strong gives the smallest files. Changing any setting switches the preset to Custom.
3Click "Compress GIF"GIFs are processed one after another with a progress message for each. Large animations can take a while, and you can stop at any time.
4Check and downloadEach result shows an animated preview, its new size and how much smaller it is. Download them one by one, or all together as a ZIP.

The settings explained

Presets: Light uses the most colors with no smoothing, Balanced uses 128 colors with light smoothing, and Strong uses 64 colors, 75% size and strong smoothing. They only fill in the settings below.
Colors: the size of the shared palette. Fewer colors mean smaller files but more visible banding in gradients.
Size: scales every frame down. This is usually the biggest saving, because a smaller picture has far fewer pixels to store.
Frames: keep every frame, or only every 2nd or 3rd one. The delays of removed frames are added to the frame that stays, so the animation takes the same time overall but looks less smooth.
Smoothing between frames: treats very small color changes from one frame to the next as no change, so less has to be stored. Strong smoothing saves more but can leave faint trails behind moving objects.
Dithering: mixes colors to hide banding when you use few colors. It adds fine noise, so the file usually gets much larger, sometimes several times larger.

How your GIFs are handled

Your GIFs are read by your browser from your device and compressed by code that is part of this page. They are not uploaded to LovePDFImg or to any other server.
No compression library has to be downloaded. If you use "Download All (ZIP)", the page loads a small ZIP library (JSZip) from the cdnjs network the first time. That download is software only and, like any web request, it shows cdnjs your IP address. Your GIFs are not part of it.
The compressed files exist only in your browser tab until you download them. Your original files are never changed. LovePDFImg does not store anything, and results are gone when you close or leave the page.
If you allow analytics in the cookie settings, Google Analytics measures page visits. File names and file contents are not sent. See the Privacy Policy and Cookie Policy.

What to know before you compress

Results vary. GIFs that were already optimized may barely shrink at gentle settings, and a result can even be larger. The list tells you when that happens, so you can keep the original.
Quality is traded for size. Reducing colors, size or frames is permanent in the new file. Keep your originals.
Animation timing and looping are kept. Frame delays and the loop count are preserved. Frame comments and other extra data in the file are not copied, and the new file is not interlaced.
Transparency stays on or off. GIF has no partial transparency, so shrinking a GIF with soft edges can make them look harder.
Size limits. You can add up to 20 GIFs at a time, each up to 50 MB, with up to 2,000 frames and about 16 megapixels per frame. Larger animations are refused rather than risking a crash.
Speed depends on your device. The work happens on your device, so long or large GIFs can take a while on a phone. Stop ends the job after the current step.
Other formats. For web pages, modern formats such as animated WebP or video are usually much smaller than any GIF, but this tool keeps the GIF format so the file works everywhere. PNG, JPG and WebP files are not accepted here, and the list points you to the matching compressor.

Frequently Asked Questions

A GIF stores every frame of an animation as its own picture, limited to 256 colors, using an old compression method. This tool reads your GIF in your browser and writes it again more efficiently. It builds one shared color palette, stores only the part of each frame that changed from the one before, and, depending on your settings, can also reduce the number of colors, shrink the picture, merge frames or treat tiny color changes as no change.

No. Your GIFs are read, processed and rebuilt by your browser on your own device. The compression code is part of this page, so no converter library has to be downloaded for it. If you use the ZIP download, the page loads a small ZIP library (JSZip) from the cdnjs network. Your GIFs are never sent anywhere.

Yes in the default settings. The tool keeps the size of each frame's delay, so the animation runs at the same speed, and it keeps the loop count of the original. If you choose to keep only every 2nd or 3rd frame, the delays of the removed frames are added to the frame that stays, so the overall timing is kept but the motion looks less smooth.

Some GIFs have already been optimized by the program that made them, and there is little left to save at gentle settings. When the result is not smaller, the list says so. Try the Balanced or Strong preset, reduce the number of colors or the size, or simply keep the original file.

Colors sets the size of the palette, and fewer colors mean smaller files but more visible banding. Size scales the picture down. Frames can keep every frame, or only every 2nd or 3rd one. Smoothing between frames treats very small color changes as unchanged so that less data is stored. Dithering mixes colors to hide banding, but it adds fine noise that usually makes the file much larger.

Yes. Transparent areas stay transparent. GIF transparency is either on or off, so if you shrink a GIF with soft edges, the edges can look slightly harder than before.

You can add up to 20 GIFs at a time, each up to 50 MB. Each GIF can have up to 2,000 frames and about 16 megapixels per frame, and very large animations are refused because they would need too much memory. Big GIFs can take a while to process because the work happens on your device, and you can press Stop at any time.
