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.

在保持长宽比的同时调整动画 GIF 的宽度。所有帧均在浏览器中缩放。

上传 GIF 进行缩放

拖放或点击以选择

将动画 GIF 缩放至任意目标宽度，同时自动保持长宽比。调整大小过程使用 Canvas API 在浏览器中逐帧运行——无需上传，无需等待。

缩小尺寸是减小 GIF 文件大小最有效的方法之一。结合“GIF 压缩”工具可实现最大程度的缩减，无需重新录制或重新转换。
