# Free Animated GIF Resizer

Resize animated GIF files with precision scaling while keeping animation timing intact. Free, browser-based, and your GIFs are never uploaded.

## What is Animated GIF Resizer?

The Animated GIF Resizer allows users to scale down physical pixel dimensions and reduce the storage footprint of animated GIFs without breaking their multi-frame playback or timing. While standard image resizers only process the first static frame of a GIF, this specialized tool unpacks every individual animation frame, rescales the 2D bitmap using bicubic or bilinear canvas interpolation, and re-encodes the entire sequence while preserving original frame delay timestamps. It is indispensable for shrinking oversized GIFs to meet strict file size thresholds on Discord (under 8MB/25MB), resizing email newsletter header animations, or fitting animated graphics into blog sidebars. A key technical limitation to remember is that enlarging small GIFs will inevitably look soft or pixelated because the tool relies on mathematical pixel interpolation rather than AI neural generation.

## How to use Animated GIF Resizer

1. **Import Animated GIF File** — Upload your animated GIF to load its full frame sequence, playback speed, and native pixel dimensions.
2. **Set Target Dimensions & Maintain Aspect Ratio** — Input your desired width or height in pixels, toggle the aspect ratio lock, or select a percentage reduction preset (50%, 75%).
3. **Re-encode and Download Resized GIF** — Click Resize GIF to process every frame through the multi-frame scaling pipeline and download your optimized animated asset.

## Frequently asked questions

### Does resizing an animated GIF mess up the animation speed or timing?

No. The resizer extracts and re-applies the exact millisecond delay timestamp embedded in each original frame, ensuring smooth and unchanged playback tempo.

### How much file size reduction can I achieve by downscaling GIF dimensions?

Reducing GIF dimensions by 50% reduces the total pixel area by 75%, typically yielding a dramatic 60% to 80% decrease in overall file size.

### Does this resizer support GIFs with transparent backgrounds?

Yes. Transparent alpha pixels and color indexing are preserved across all frames, ensuring your resized GIF retains its transparent background.
