Compress GIF Online
This GIF compressor runs in your browser, so there is no upload queue and no file size cap. Three steps:
- 1
Upload your GIF
Drop one GIF or up to 20 at once, choose them from your device, or paste from the clipboard. A single GIF is compressed right away with the Balanced level so you see the result immediately.
- 2
Choose compression level
Lossless keeps every pixel. Balanced, Strong and Maximum trade a little color accuracy for much smaller files. Or pick Target size and let the compressor find the best quality under 256 KB, 1 MB, 5 MB or your own limit.

Download the smaller GIF
Compare the original and compressed GIF side by side, check the new size and how much you saved, then download — one file, or all of them as a ZIP.
Reduce GIF Size without Losing Quality
The first thing the compressor does is lossless optimization: frames after the first only store the rectangle that changed, and pixels inside it that stayed the same become transparent, so the previous frame shows through. A single shared color table replaces per-frame tables where possible. The picture stays pixel-for-pixel identical — only the way it is stored changes.
When you need a smaller file than that, lossy compression lets each pixel use a very slightly different color if that makes the data compress better. At the Balanced level the difference is below what most people can see, while the GIF file size drops noticeably.
Need a hard limit? The GIF file size reducer mode hits a target size for you, and six ways to reduce GIF size explains which settings help most.
| Level | What changes | Best for |
|---|---|---|
| Lossless | Nothing visible — storage only | Screen recordings, exports from editors |
| Balanced | Tiny color shifts, 256 colors | Most GIFs |
| Strong | 128 colors, light noise | Video clips, memes |
| Maximum | 64 colors, visible grain | Hard size limits, emoji |
The result always shows the size before and after. If a compressed file would be larger than your original, you get the original back.
Compress Animated GIF — Keep Every Frame
Many compressors make animated GIFs smaller by quietly throwing frames away or flattening the timing to a fixed frame rate. Here, compression never removes a frame unless you ask it to:
- Every frame delay is copied exactly, including deliberate pauses and zero-delay frames.
- The loop count is kept — loops forever, loops N times, or plays once.
- Transparent GIFs stay transparent, and frames that clear parts of the image are re-encoded with the right disposal, so no ghost trails.
- Identical consecutive frames can be merged into one longer frame — same look and timing, fewer bytes.
- Dropping frames is opt-in: remove 1 in 2, 3 or 4 frames and the removed time is added to the frame before.
The result card lists frames and duration before and after, with a check mark when they match. More detail in how to compress an animated GIF.
GIF Optimizer Tips
A GIF is a stack of up to 256-color frames, each squeezed with LZW compression. Every trick for a smaller GIF works on one of three things: how many pixels are stored, how many colors they use, and how predictable they are for LZW.
1. Store only what changes
In most animations only part of the picture moves. Storing just the changed rectangle, with unchanged pixels marked transparent, is the biggest lossless win — especially for screen recordings and UI demos, where a GIF can shrink by 70–80%.
2. Fewer, steadier colors
Each frame can use up to 256 colors. Cutting to 128 or 64 shrinks the data and makes long runs of the same color more likely. Keeping large flat areas (backgrounds, text) on exactly the same color in every frame avoids flicker and helps frame differencing find unchanged pixels. Dithering — scattering dots of two colors to fake a third — looks smooth but compresses badly; use it only where gradients need it.
3. Lossy LZW
LZW saves space by reusing sequences it has seen before. Lossy LZW allows a pixel to take a nearly identical color when that lets it reuse a longer sequence. It is the most efficient lossy step for video-like GIFs because the changes are spread thinly across the image.
4. Frames: merge duplicates, then drop if you must
Consecutive identical frames can always be merged at no cost. Dropping every 2nd frame halves the frame count and often the size, but motion gets choppier — fine for slow scenes, noticeable for fast action. Keep the total duration by giving removed frames’ time to their neighbors.
5. Smaller dimensions
Pixels grow with the square of the size: a GIF at 50% width and height has a quarter of the pixels. Scaling down is the most reliable way to reach a hard limit.
What each technique saved on three test GIFs, compressed with this tool:
| Technique | Screen recording 198 KB, unoptimized export | Video clip 199 KB, converted with ffmpeg | Cartoon loop 50 KB, flat colors |
|---|---|---|---|
| Lossless optimization | −79% | 0% | −6% |
| 64 colors | −80% | −29% | −24% |
| Lossy (Balanced) | −86% | −14% | −42% |
| 128 colors + stronger lossy (Strong) | −87% | −28% | −42% |
| Scale to 50% | −73% | −39% | −30% |
| Drop every 2nd frame | −84% | −49% | −47% |
The first row shows why “already optimized” matters: the video clip was optimized by ffmpeg when it was made, so only lossy steps help. For a step-by-step workflow, see how to optimize a GIF for the web or the lossless GIF optimizer.
FAQ
How do I compress a GIF without losing quality?
Choose the Lossless level. It re-encodes the GIF so that only the pixels that change between frames are stored and unchanged areas become transparent, which keeps every pixel identical. Well-optimized GIFs may not shrink this way — then Balanced is the next step; its lossy compression changes colors by amounts you normally cannot see.
How much smaller will my GIF get?
It depends on how the GIF was made. Unoptimized exports (many screen recorders and editors) often shrink by 50–80% losslessly. GIFs converted from video usually shrink 10–15% at Balanced and 25–30% at Strong. Dropping every second frame or halving the dimensions typically saves 30–50% on its own.
Will compressing change the speed or length of my GIF?
No. Each frame keeps its original delay and the loop setting is kept. If you choose to drop frames, the time of each removed frame is added to the frame before it, so the GIF still plays for the same total duration.
Is there a file size or upload limit?
Nothing is uploaded — GIFs are compressed by your browser — so there is no upload limit. Very large or very long GIFs are limited only by your device’s memory; up to 200 MB per file and 20 files at a time.
Can I compress a GIF to a specific size, like under 256 KB?
Yes. Switch to Target size and pick Discord emoji (256 KB), Slack emoji (128 KB), email (1 MB), X (5 or 15 MB) or type your own limit. The compressor tries the lightest settings first and returns the best-looking version that fits.
Why did my GIF not get smaller?
Some GIFs are already optimized, and re-encoding them losslessly gains nothing. When that happens you keep the original file. Try Balanced or Strong, fewer colors, a smaller size, or dropping frames.
Is this GIF compressor free? Does it add a watermark?
Yes, it is free, needs no account and never adds a watermark. You can compress up to 20 GIFs at once and download them together as a ZIP.
Are my GIFs private?
Yes. Your files never leave your device: the compression runs in a background worker inside your browser tab. Closing the tab discards everything.
