How to use Crop GIF
- Choose the source file or ordered images.
- Review animation-specific controls.
- Preview and download the measured result.
Crop GIF
Apply one source-space crop consistently to every frame of an animated GIF.
Crop GIF uses a separate frame-aware pipeline; it never sends an animated file through the static first-frame canvas path.
How OpenFileTools processes it
Local processing, explicit choices.
The browser lazy-loads GIF decoding and encoding code, composites disposal-aware frames, applies the operation to every frame, and creates an animated GIF locally.

One source-space crop for every frame
Move or resize the crop rectangle over the animated preview, select a ratio, or enter X, Y, width, and height. The resulting source-space rectangle is applied identically to every composited frame.
- Free and seven aspect presets are available.
- Numeric controls provide a keyboard-accessible fallback.
- Frame-to-frame crop drift cannot occur.
Questions, answered.
Does each frame get a different crop?
No. Every frame uses the exact same rectangle.
