1. Convert GIF to multiple sprite sheets
Select your GIF in the converter below. This is the same converter as before. This time instead of selecting 1 sprite sheet, select more.
The converter will automatically suggest you a number of sprite sheets to use, but you're free to to use more or less. You can use the Approximate Roblox preview section to check how many sprite sheets you need to make a GIF look good, but please note that we don't know how Roblox compresses images and the final quality might be worse.
You shouldn't go crazy with the amount of sprite sheets. Please remember that you'll need to upload every sprite sheet and each of them will need to be loaded in-game. Most of the time 2 or 3 sheets is as high as you need to go to get decent quality.
Press the Download sprite sheets button. Your browser will download a .zip file containing all images. Please note that the images are named in order (first one starts with a 1, the second one starts with a 2 and so on) and this order is very important.
Save the code in the Roblox script section to a notepad, just like before.
Upload all images from that zip to Roblox.
