Quick Answer: Resize
To resize a GIF online, use Gifur's resizer at gifur.com/tools/resize. Enter your target width (the height adjusts automatically to maintain aspect ratio). Reducing dimensions significantly decreases file size.
Gifur uses Lanczos scaling for GIF resizing, which provides superior quality compared to bilinear interpolation.
Reducing GIF width by 50% can decrease file size by up to 75% due to fewer pixels per frame.
High-quality Lanczos scaling — Resize GIFs anywhere from 50 to 2000 pixels wide. Halving the width usually cuts file size by around 75%.
Gifur GIF Resizer is a dimension adjustment tool that scales animated GIFs from 50px to 2000px width using high-quality Lanczos algorithm while preserving aspect ratio.
✦ Reducing GIF dimensions by 50% typically reduces file size by approximately 75% due to the quadratic relationship.
