Crop a GIF online free — animated GIF cropper tool

Crop a GIF online free. Trim, cut, and crop animated GIFs to any size with this easy GIF cropper. Instant preview, no quality loss. No upload, works in.

What is a GIF Cropper Tool?

A GIF cropper is a specialized tool that lets you trim and resize animated GIF images while preserving all animation frames and timing. Unlike regular image croppers that only handle static images or flatten GIFs to a single frame, this tool parses the complete GIF structure — extracting every frame, its delay timing, and disposal method — crops each frame to your selected region, and reconstructs a fully animated GIF. This free online GIF cropper runs entirely in your browser: upload a GIF, drag the crop rectangle to select the area you want to keep, and download a perfectly cropped animated GIF with all original animation intact. No uploads, no software, no watermarks.

Animated GIF Cropper Features

Everything you need to crop and trim animated GIFs.

  • Preserves Animation

    All frames, frame delays, and animation timing are preserved. The cropped GIF plays exactly like the original.

  • Interactive Crop Rectangle

    Drag to position the crop area, pull corner handles to resize, or click inside to move. Live pixel dimension display.

  • Animated Preview

    See the original GIF playing while you adjust the crop. The preview updates in real-time so you know exactly what you'll get.

  • Client-Side Processing

    GIF parsing, frame cropping, and re-encoding all happen in your browser. No data leaves your device.

  • Pixel-Accurate Dimensions

    See the exact width and height of your crop area in real-time. Crop to precise pixel dimensions.

How to Crop an Animated GIF

Three simple steps to crop any GIF animation.

  1. 1. Upload Your GIF

    Drag and drop an animated GIF file into the upload area, or click to browse from your device. The GIF will appear with an animated preview.

  2. 2. Adjust the Crop Area

    Drag the corners or edges of the crop rectangle to resize it. Click and drag inside the rectangle to reposition it. The dimensions update in real-time.

  3. 3. Download Your Cropped GIF

    Click Download Cropped GIF to save the result. The cropped GIF preserves all original animation frames with the exact crop region you selected.

Tips for Cropping GIFs

Best practices for getting the best results.
  • 01

    Keep the Subject Centered

    Position the crop rectangle around the main subject of the animation. The tool center-crops by default, so start from there.

  • 02

    Use Square for Social Media

    Many platforms prefer square GIFs. Use the 1:1 lock (equal width and height) when cropping for Instagram, Twitter, or Discord.

  • 03

    Mind the File Size

    Cropping reduces pixel count, which usually means smaller file size. This is great for sharing GIFs where size limits apply.

  • 04

    Check All Frames

    If your GIF has significant motion, make sure the subject stays within the crop rectangle across all frames before downloading.

  • 05

    Avoid Cropping Too Small

    Very small crops (< 50px) may look pixelated. GIF format works best at reasonable dimensions — aim for at least 100px on the shortest side.

  • 06

    Preview Before Downloading

    Review the crop dimensions shown on screen to make sure you're cropping exactly what you want before downloading.

Technical Details

How the GIF cropping works under the hood.
GIF Binary Parsing
The tool parses the raw GIF binary format — reading headers, color tables, Graphics Control Extensions (frame delays), Image Descriptors, and LZW-compressed image data.
LZW Decompression & Compression
Each frame's pixel data is LZW-decompressed into raw color indices, cropped, and then LZW-compressed back into the output GIF format.
Color Palette Management
A global 256-color palette is generated from the first frame using 5-6-5 color bucketing. Transparent areas are preserved via the alpha channel.
Client-Side Processing
All parsing, cropping, palette generation, and GIF encoding runs entirely in JavaScript in your browser. No server processing.
Supported Input
Animated GIF files up to 15 MB. Supports both GIF87a and GIF89a formats with looping, transparency, and interlace.
Output Format
Output is a standard GIF89a file with looping enabled, matching the original frame delays and preserving transparency.
