A GIF resizer changes an animated GIF’s canvas dimensions and resamples every complete frame. VisualFormat lets you keep the original proportions or enter a custom width and height. The output remains an animated GIF.

HELPFUL ANSWERS
GIF Resizer FAQs
Animation, dimensions, file size, and privacy.
How do I resize an animated GIF?
Choose a GIF, set the output width and height or select a percentage, then select Resize GIF. Preview the result and download the animated GIF.
Can I resize a GIF without losing animation?
Yes. Every complete frame is resized. Frame order, encoded delays, and the original loop setting are preserved. Very short delays may play differently in different viewers.
How do I resize a GIF while keeping its aspect ratio?
Leave Keep aspect ratio checked. Changing the width calculates the corresponding height, and vice versa, rounded to whole pixels. Percentage presets also keep the original proportions.
Will resizing make my GIF smaller in bytes?
Often, but not always. Smaller dimensions can reduce file size, while rebuilding optimized frames can increase it. The result shows both file sizes. Use the GIF Compressor if your main goal is fewer bytes.
How is the GIF resampled?
This tool samples the nearest pixel at each output pixel center. This keeps sharp pixel edges and binary transparency without interpolation. Upscaling makes pixels larger and cannot restore missing detail. Complex frames with more than 256 composite colors may need palette reduction, which is disclosed.
What are the limits, and is my file uploaded?
Your GIF stays on your device. Input is limited to 20 MB, 500 frames, 4,096 pixels per dimension and 40 million full-frame pixels. Output has the same dimension and pixel-count limits, plus an 80 MB encoded-size limit. No account, watermark, paid API, or AI is required.
