About Resize GIF
The height follows the width so the GIF keeps its shape. Every frame is resized with high-quality scaling and the colours are rebuilt with a fresh palette for the new size.
Processing happens in this tab with FFmpeg compiled to WebAssembly; your files are never uploaded. The first video or audio tool you use downloads the 10 MB engine once and keeps it cached for next time. Long or high-resolution videos take longer than on a desktop editor, especially on phones, where files are processed one at a time to stay within memory. Keep the tab open until the download appears.
Resize GIF: frequently asked questions
How do I resize a GIF without losing the animation?
Choose the GIF and a width: 640, 480, 320 or 240 px, or your own. Every frame is resized and the animation is kept.
Will the GIF be stretched?
No. The height follows the width, so the GIF keeps its shape.
Why do the colours look different after resizing?
A fresh palette is built for the new size, which usually keeps the colours close to the original.
Can I resize several GIFs at once?
Yes. Add a batch and each one is resized to the same width.
