Sprite Sheet Stitcher
Literally just stitches together PNGs to a sprite sheet.
Select the folder the frames are in
Select how many rows you want
Save it
It’s literally just a little vibe coded tool, Windows will scream that it might be unsafe to use.
If you don’t trust us you can get the source code from GitHub here and just compile it yourself:
