How to compress a GIF's file size

A GIF is heavy for two reasons. An animated GIF stores a sequence of full frames, so a few seconds of motion can add up to hundreds of individual images stacked into one file. And GIF is limited to a palette of 256 colors, so photographic content gets dithered — a speckled pattern that fights compression and inflates the size further.

That's why a short clip saved as a GIF can easily be several megabytes. The good news: there's real room to shrink it, and the single biggest lever depends on whether your GIF is animated or a single still frame.

Open the GIF compressor and drop your file in — you can load several at once. It re-optimizes the GIF and shows you the new size so you can check the result before you keep it:

• Drop your GIF into the compressor.
• Let it re-encode the file and compare the before-and-after size.
• Export and download the smaller copy.

Everything runs on your device — you can disconnect from the internet after the page loads and it still works, which is the plainest proof your file isn't being uploaded anywhere.

If your GIF is animated, the way to make it smaller and keep it moving is to compress it as a GIF. The GIF compressor reduces the color palette and optimizes the frames, and the animation keeps playing — it stays a .gif that works everywhere the original did. Two levers move the number most: capping the maximum dimension (halving the width takes three quarters of the pixels out of every frame) and trimming the clip to fewer frames before you compress.

What about WebP? As a format it does support animation, and it stores motion far more efficiently than GIF — that part is true. But EditItAll's GIF to WebP converter converts the first frame of an animated GIF, so what comes back is a still image. That is exactly right when you want a thumbnail or a poster frame, and exactly wrong when the motion is the point. Producing an animated WebP needs a different tool than this converter — we'd rather say so than let you find out once the animation is gone. The guide to converting GIF to WebP covers that case in full.

GIF still has one real advantage: it opens absolutely everywhere with zero fuss, which is why some chat apps, forums and email clients accept it and nothing else. For a single still frame, the palette limit also matters less, so compressing it directly is often enough.
