How to resize a GIF without stretching it
Choose your GIF and enter a new width in pixels. The height adjusts automatically using the original aspect ratio, keeping circles round and characters in proportion. We preserve the animation frames and their timing while re-encoding at the chosen size.
For a 640 × 480 GIF, entering a width of 320 produces a 320 × 240 output. Reducing size can make GIFs easier to share in messages, websites, and documentation.
Tips for better GIF resizing
- Resize down rather than up whenever possible to avoid blurry enlargements.
- Preview transparent edges and detailed artwork after export.
- For smaller file sizes, try the GIF Compressor after resizing.
Frequently asked questions
Does resizing keep the GIF animated?
Yes. The editor processes all decoded frames and recreates an animated GIF with the same nominal timings.
Can I enter a custom height too?
This tool keeps the original aspect ratio to avoid distortion, so the height is calculated automatically from the width.
What is the maximum output width?
The current browser tool supports output widths up to 800 pixels, with a maximum output area of one million pixels.
