Resizing animated GIFs

- Set size. Width presets, exact pixels, or a percentage — aspect stays locked unless you unlock it.
- Resize. Every frame is resampled together, then re-encoded — the output is a real animated GIF.
Frequently asked questions
Will upscaling stay sharp?
GIF is a bitmap format — enlarging softens it; shrinking stays crisp. Bilinear sampling keeps edges smooth.
Does the animation survive?
Yes — every frame is scaled and re-encoded as GIF; frame delays and looping are preserved.
How does the ratio lock work?
Locked by default — set the width and height follows; unlock to stretch freely (image will distort).
Are files uploaded?
No — everything runs locally in your browser.
