GIF Cropper — Crop GIFs Without Losing the Animation

Crop a GIF right in your browser

This GIF cropper cuts the same rectangle out of every frame of an animated GIF, so the motion, frame delays, loop count and transparency all survive the crop. It runs on your own machine with WebAssembly — your file never leaves the device, nothing is stored, and there's no signup, watermark or export limit. Crop freehand or to a preset ratio.

We built the compressor first. Then we watched people feed it 1280px screen recordings where a third of the picture was browser tabs and desktop wallpaper, and realised half of them didn't need smaller bytes — they needed a tighter frame. So here's the cropper.

How to Crop a GIF

Cropping a GIF here takes three moves: add the file, set the crop area, download the result. There's nothing to install and no queue to wait in, because the work happens in your browser. Batch cropping works the same way — add several GIFs and apply one crop region across the whole queue.

1. 1.Add your GIF

   Drop a GIF onto the tool, paste one from your clipboard, or paste a direct image URL. Files stay on your device.

2. 2.Set the crop area

   Drag the crop box and its handles over the part you want to keep, or pick an aspect ratio preset like 1:1 or 16:9. Auto-trim snaps the box to the content if the GIF has borders.

3. 3.Download the cropped GIF

   Press Crop GIF, check the before and after, then download the file — or grab a .zip if you cropped a batch.

Pro tip: play the animation before you commit. The subject moves, and a crop that looks perfect on frame 1 can slice the punchline off frame 40. That's the whole reason the crop box sits over a live preview instead of a still thumbnail.

What cropping an animated GIF actually does to the file

A GIF is a stack of frames plus a colour palette and a set of delays. Cropping an animated GIF cuts the identical rectangle out of every one of those animation frames and rewrites the canvas size, so the picture gets smaller but the timeline doesn't change. Fewer pixels per frame means fewer bytes, which is why a crop usually shrinks the file too.

Why naive croppers smear the animation

Most GIFs in the wild are frame-optimized: each frame stores only the rectangle that changed since the last one, positioned with an offset. Crop that blindly and you're cutting different regions out of different frames, which is how you end up with ghost trails and pixels that smear across the loop.

So we coalesce first. Every frame is expanded back to a full picture, the crop is applied to all of them equally, then the inter-frame optimization is put back afterwards so the output doesn't balloon. You get a clean cut and a file that's still tidy.

Cropping cuts bytes as well as pixels

Take a 1280×720 screen recording at 98 KB. Cut the browser chrome and taskbar and it becomes 1280×616 at 90 KB — 14% of the pixels gone, 8% of the bytes. The saving lags the pixel count because the palette, headers and per-frame overhead don't shrink with the picture. Cut more picture, save more bytes, but never quite one-for-one.

Cropper, GIF cutter or trimmer — which one do you need?

Cropping a GIF cuts space: pixels off the edges of every frame. Trimming or shortening a GIF cuts time: whole frames off the start or end. Resizing scales the entire picture down without removing anything. People say "cut a gif" for all three, which is why searching for a GIF cutter turns up three different kinds of tool.

• This tool crops. It changes the GIF dimensions and leaves the animation frames alone.
• To change the whole canvas without cutting anything away, use the GIF resizer.
• To shrink the file without changing what's visible, run it through our GIF compressor after you crop.

Crop a GIF to square, 16:9, or PFP size

The aspect ratio presets lock the crop box to a fixed shape while you drag it: Free for no constraint, 1:1 for a square GIF, 16:9 for widescreen, 9:16 for vertical, and 4:3 or 3:2 for older captures and photo framing. Pick a preset, position the box, and the width and height stay in proportion the whole time.

Cropping a GIF for a profile picture

Nearly every platform crops an avatar to a square before it displays it. If you upload a widescreen GIF, the platform's auto-crop decides what stays — and it usually picks dead centre, which is rarely where your face is. Do the pfp crop yourself at 1:1 and you keep that decision.

About "circle" GIFs

A GIF file is always a rectangle. There's no round GIF in the format, so a circle GIF is either a square GIF sitting behind a platform's round mask, or a square GIF with a transparent background in the corners. Crop to 1:1 and the round version takes care of itself on any site that displays avatars as circles.

Banner crop is the same idea in the other direction: wide and short, usually 3:1 or wider, so use Free and type exact numbers into the width and height fields.

We cropped 20 GIFs and measured every one

To find out how much cropping a GIF really saves, we built 20 test GIFs across four shapes of problem — screen recordings with browser chrome, memes with dead space, letterboxed clips and widescreen sources cropped to a square avatar — and ran each one through the exact crop pipeline this page uses. Here's what came out.

Across all 20 files the median crop removed 36% of the pixels and 22% of the bytes — about 0.6 bytes saved for every pixel cut. The gap is palette and header overhead, which doesn't shrink when the canvas does.

The square avatar crops were the outlier, giving back 44 to 47% for 44% of the pixels, because the discarded region was busy background. Cropping quiet black letterbox bars paid the least: 33% of the pixels, only 11 to 16% of the file. Empty pixels were already nearly free.

Last tested: August 2026.

What people are actually cropping GIFs for

Cropping an animated GIF is almost never about art direction. It's about a platform that wants a particular shape, or a recording that caught more of your desktop than you meant. These six jobs cover nearly every GIF that goes through this cropper, and each one has a preset that fits it.

Questions we get about cropping GIFs

The same handful of questions turn up in our inbox every week: whether the animation survives, how to get a square, whether Windows needs an app, and where the file size goes. Short honest answers below, including the one thing this tool deliberately doesn't do.
