Only the size changes. Timing, frame count and colours stay the same, and the result loops forever.

Add one animated GIF.
Choose a percentage, or enter a width and height. "Keep proportions" is on by default.
Press Resize, then download the result.

What changes?: Only the size in pixels. The number of frames, how long each is shown and the colours stay as they were.
Do the colours really stay the same?: When the GIF uses 256 colours or fewer in total, the resized frames are mapped back onto those same colours. A GIF with more than that is saved with 256.
Does it loop?: Yes. The result always loops forever.
Can I make it bigger?: Yes, but the picture gets no more detail, so it looks soft.
Is transparency kept?: Yes. A GIF can only be fully transparent or fully solid, so soft edges become hard.
