How do you resize an animated GIF without breaking the animation?
Unlike static images, an animated GIF consists of dozens of individual graphic frames, each with its own timestamp delay and disposal method. Resizing requires decoding every single frame, scaling each raster canvas proportionally using bicubic interpolation, and re-encoding the entire sequence with identical frame delay intervals into a new GIF container with synchronized color palettes.
Key Takeaways
- Scales every frame in the animation sequence proportionally.
- Preserves exact frame delays, animation playback speeds, and loop count.
- Maintains aspect ratio to prevent stretching funny or animated subjects.
- Zero watermarks: Exported GIFs remain clean and completely unbranded.
