Question 1

Are my images sent to a server?

Accepted Answer

No. All images are processed locally in your browser and nothing is uploaded anywhere.

Question 2

What decides the output GIF width and height?

Accepted Answer

The output width/height defines the GIF canvas size. By default, the tool uses the maximum width and height among the selected images, and you can override it manually.

Question 3

Why doesn't the background color look different?

Accepted Answer

If the image fully covers the canvas (cover/stretch, or same aspect ratio), the background is hidden. It's mainly visible with Contain when letterboxing appears, or when images have transparent areas.

Question 4

What if my images have different sizes?

Accepted Answer

Pick a fit mode (contain / cover / stretch) and set a unified output width and height to control the canvas.

Question 5

How do I control animation speed?

Accepted Answer

Use the frame delay setting. Smaller delays play faster, while larger delays slow the animation down.

Question 6

How do I change frame order?

Accepted Answer

Use Move up / Move down in the image list. The exported GIF follows the current order.

Question 7

How can I reduce the GIF file size?

Accepted Answer

Use fewer images, increase the frame delay, reduce output width/height, or choose a faster quality preset. Bigger canvas and more frames increase file size and encoding time.
