BrushNinja File Format
A .brushninja file is an editable project file created by Brush Ninja.
It is specific to the Brush Ninja Animation Maker.
It stores everything needed to reopen an animation exactly as it was left, including frames, drawings, and timing. Unlike an exported GIF or image, a .brushninja file may not be a finished animation. It is designed for editing, not for sharing as final work.

What a .brushninja file is used for
A .brushninja file allows an animation to be continued later, moved between devices, or reopened after closing the browser. Teachers often use these files to prepare starter projects, and students can use them to continue longer pieces of work across multiple lessons.
Because the file keeps the animation editable, changes can still be made to drawings, frames, and timing.
When to use this file format
This format is most useful while an animation is still being worked on. It is ideal for saving progress, resuming work on another device, or sharing an editable project with someone else.
When an animation is finished and ready to be shared, it should be exported as a GIF or image instead.
Saving and reopening projects
To save a project, use the Save option in Brush Ninja. This downloads a .brushninja file to the device being used.
To continue working later, open Brush Ninja again and use the Open option to load the file. The editor will restore the animation so that editing can continue.
Important things to know
.brushninja files only open inside Brush Ninja and cannot be viewed like images or videos. They should be named clearly so they can be identified easily, especially when working on shared devices.
A .brushninja file is an editable project file, not a finished animation. It is used to save progress, move work between devices, and continue editing later. Final work should always be exported as a GIF or image for sharing or submission.
