Parallixel for Aseprite

Parallixel – Parallax Scrolling Made Easy in Aseprite

Parallixel is an Aseprite extension that automates the creation of seamless parallax scrolling effects.

Originally inspired by Godot’s parallax system, it began as a personal tool to preview scrolling layers and mock up character movements  directly inside Aseprite, without relying on external tools. Now, it's a full-featured extension that makes parallax animation fast, intuitive, and entirely engine-free.

Reminder: Processing larger images and/or higher frame count may take additional time.

Note: The number of frames you set will automatically adjust based on the selected animation frames to ensure a smooth, seamless loop. The example above animation includes layers with 4, 8, and 10 frame loops, the final frame count will adjust to 40, the least common multiple (LCM), to synchronize all layers perfectly.
