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.

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

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

Yes, but upscaling may make the image appear blurry or pixelated since GIF resolution is limited.

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

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

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

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

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