GIF Cropper

Crop animated GIF files without flattening them

This tool crops every frame, not just the first one. It decodes the full sequence, applies one rectangle to each frame, and re-encodes the animation with its original frame delays, so frame count and playback length come out unchanged. Only the framing is different.

That is worth stating plainly because the common failure is the opposite. Many general image croppers read a GIF as a single still, crop frame one, and hand back a picture that no longer moves. If you have been burned by that, this page is the fix.

Crop versus resize: the distinction people get wrong

Cropping removes pixels from the edges. The picture gets smaller and the framing changes, because part of the scene is now outside the frame and gone for good. Resizing keeps the entire picture and scales it down, so nothing is lost but every detail is rendered with fewer pixels.

Both make the file smaller, and that overlap is why the two get confused. The question to ask is whether you mind losing what is at the edges.

Crop when the edges are the problem

Crop to cut a letterboxed black bar, a watermark, a browser chrome strip on a screen recording, or a distracting background. Crop to change shape — a 16:9 screen capture is useless in a 9:16 Story until something is removed. Crop to push the subject larger in frame.

Resize when the whole picture matters

Resize when everything in frame has to survive and the file is simply too big: a full-width demo, a chart, a diagram. Scaling a GIF down loses fine detail everywhere rather than losing whole regions. Use the free image resizer for stills, or the GIF compressor when the animation needs to keep its full frame at a smaller size.

Why cropping an animated GIF often shrinks the file sharply

A GIF stores pixels for every frame, so removing area removes it from all of them at once. Halving both width and height leaves a quarter of the pixels per frame, and across a 120-frame animation that is 90 frames' worth of data gone. This is why cropping is often a bigger lever on a GIF than on a still image. The other levers are covered in why GIF files get so large.

The saving tracks the pixel-area ratio only loosely, because GIF compression is content-dependent. LZW compresses runs of identical palette indexes, and a 256-colour palette is fitted to whatever is left in frame. Crop away a busy, noisy background and the remaining region can both compress better and need fewer colours, so the file can drop further than the area ratio alone predicts.

It can also go the other way. Crop away a flat background, keep only the busy subject, and the pixels you kept are the expensive ones — so the file lands above the area ratio. The before and after byte counts beside the download button are measured, not estimated.

One thing to keep in mind about the numbers

The output here is a fresh encode at 256 colours with a single global palette, so a small part of any size change comes from re-encoding rather than from cropping. If your goal is a byte target rather than a shape, crop first and then run the result through the GIF file size reducer, which searches settings against a size limit.

Aspect targets for social platforms

The four presets cover almost every placement a GIF ends up in. Pick the ratio first, then drag — the box keeps the shape while you move and resize it, so you cannot end up two pixels off square.

For a ratio that is not on the list, work out the target pixel dimensions in the aspect ratio calculator and type them into the width and height fields. Every value you enter is clamped to the frame, so a crop box can never run off the edge of the source.

What cropping cannot fix

Cropping only ever removes pixels. It cannot add detail, repair colour, or undo a decision made when the GIF was first encoded. Two limits catch people out.

A low-resolution source gets worse, not better

Crop a 320 × 240 GIF down to a 120 × 120 square and you have a 120-pixel-wide image. Blown back up to fill a feed post it will look soft and blocky, because the missing detail was never captured. Crop from the largest version you have, and if the only copy is small, re-export from the source video instead.

Dithering and banding survive the crop

Many GIFs are dithered — a scatter of alternating pixels used to fake colours the 256-entry palette does not contain. Cropping keeps that pattern at its original scale, so the speckle becomes more visible as the crop gets tighter. No cropper can remove it; re-exporting from the original footage can.

Cropping is not trimming

Cropping changes space, not time. It cannot shorten an animation, drop frames or slow playback — a GIF that is too long stays exactly as long. To work on time instead, split the GIF into its individual frames and see each frame's delay.

How to crop an animated GIF online here

Drop a GIF, or choose one with the file picker. The first frame is painted on the canvas with a crop box already centred over it, and the source dimensions, frame count and length appear underneath.

Pick an aspect preset if you have a target shape, then drag inside the box to move it and pull any of the eight handles to resize it. Keyboard users can focus the box and nudge it with the arrow keys, resize with shift and the arrow keys, or move in 10-pixel steps with alt. The four number fields do the same job for anyone who would rather type exact coordinates.

Output dimensions, the resulting ratio and the share of the pixel area removed update as you drag. Press Crop GIF, watch the progress bar, then download — the result panel reports the new size against the old one.

GIF cropper FAQ

Does cropping an animated GIF keep it animated?

Yes. This animated GIF cropper decodes every frame, applies the same rectangle to each one, and re-encodes the whole sequence with its original frame delays. Frame count and playback length are unchanged — only the framing is different. Ordinary image croppers often keep frame one and throw the rest away, which is the usual reason a cropped GIF comes back as a still.

What is the difference between cropping and resizing a GIF?

Cropping cuts pixels off the edges, so the picture gets smaller and the framing changes — part of the scene is gone. Resizing keeps the entire picture and scales it down, so nothing is lost but everything is less detailed. Crop to change what is in frame; resize to keep everything at a smaller size.

Will cropping make my GIF file smaller?

Usually, because every frame carries fewer pixels. The saving tracks the pixel-area ratio only loosely, because a GIF compresses better when the remaining region is flat and worse when it is busy.

How do I crop a GIF to a square?

Load the GIF, choose the 1:1 preset, then drag the box over the part you want to keep. The box stays square while you drag it, and the width and height fields stay locked together. Output dimensions are shown live above the crop button.

Is my GIF uploaded to a server?

No. Decoding, cropping and encoding all run in your browser tab, so the file never leaves your machine. The GIF codec downloads the first time you use it; after one file the tool keeps working without a connection until you close the tab, and it works on footage you would not hand to a website.

How large a GIF can this handle?

Up to 100 MB, 600 frames and about 2.07 million pixels per frame (1920 × 1080 or the same pixel count). All decoded frames must also fit a 512 MB memory budget, so a full 1920 × 1080 GIF can run to about 64 frames and smaller frames can run longer. Past those limits the tool refuses the file with a message instead of freezing the tab.

Can I crop a video instead of a GIF?

Convert it first. The video-to-GIF converter turns an MP4, MOV or WebM clip into a GIF in the browser, and you can then crop the result here.
