How do I resize a GIF without distortion?

Enter a target width — the height is automatically calculated to maintain the original aspect ratio.

Can I set both width and height independently?

Yes. Uncheck the 'Lock Aspect Ratio' option to enter custom width and height independently, though this may distort the animation.

Does resizing reduce file size?

Yes, significantly. Halving the dimensions (e.g., 800px → 400px) typically reduces file size by 60–75%.

What interpolation method is used for resizing?

The browser's built-in Canvas 2D bilinear interpolation is used, which provides good quality for most GIFs.

Can I make a GIF larger (upscale)?

Not in this tool — GIF Resize only shrinks to a smaller width. Upscaling is planned as a separate tool.

What is the maximum output resolution?

There is no hard limit, but very large GIFs (e.g., 4K) will be slow to encode and result in huge file sizes.

Will resizing affect the animation speed?

No. Frame delays and loop count are preserved exactly as in the original GIF.

Does resizing affect GIF color quality?

Re-encoding re-quantizes to 256 colors. For GIFs that already have few colors, the impact is negligible.

Can I resize multiple GIFs at once?

Currently, one GIF is processed at a time. Batch processing may be added in a future update.

Why is my resized GIF still large in file size?

File size depends on image complexity, number of frames, and color count — not just dimensions. Use the GIF Compress tool for further size reduction.
