Frequently Asked Questions — GIF Resizer
Is the GIF resizer free?
Yes, completely free. No registration, no hidden charges, and no watermarks. All processing happens locally in your browser.
How does GIF resizing work?
Each frame of the GIF is drawn onto a canvas at the new dimensions using the browser's image resizing, then re-encoded into a new GIF.
Does resizing affect GIF quality?
Resizing uses the browser's built-in canvas smoothing for high-quality results. Enlarging may cause pixelation since source pixels are stretched.
Can I resize by percentage?
The tool accepts pixel dimensions, but you can calculate percentage values manually.
What are the dimension limits?
Maximum dimension is 4096 pixels on either side. Minimum is 16 pixels. GIFs with up to 200 frames are supported.
Does resizing change GIF speed?
No, resizing only changes the pixel dimensions. Frame timing and animation speed are preserved exactly.
What image formats are supported?
Only animated GIF files are supported since this tool specifically resizes GIF animations.
