How to resize a GIF
1. Upload your GIF
Drop any animated GIF into the tool or click to browse. Preview loads instantly.
2. Set dimensions
Enter a new width — height auto-adjusts to keep the aspect ratio locked. Or set both manually.
3. Adjust FPS
Lower frame rate reduces file size significantly. 10fps is a good default for most GIFs.
4. Download
Click Resize GIF — all frames are processed in your browser. Download the result instantly.
Frequently Asked Questions
- Is my GIF uploaded to a server?
- No. All processing happens inside your browser using the Canvas API and a local GIF encoder. Your file never leaves your device.
- Can this resize animated GIFs?
- Yes. Every frame of the animation is decoded, scaled, and re-encoded at the new size. The animation plays correctly at the new dimensions.
- How do I make a GIF file smaller?
- Reduce the width (biggest impact), lower the FPS, or increase the quality number (higher = more compression). Width reduction alone can cut file size by 75% or more.
- Does resizing a GIF reduce quality?
- Reducing dimensions always reduces some detail — that's expected. The Quality setting controls color dithering. Quality 1–5 gives the best colour accuracy; 10–20 gives smaller files with more visible dithering.
