CropBox is a compact tool for After Effects that deals with a chore every motion designer knows well. Compositions often end up larger than the artwork inside them, with wide empty borders that make exports messy and previews slower than they need to be. CropBox focuses on trimming a composition down to the content that actually matters, so the frame fits the layers instead of the other way around. It is a narrow tool, and that is the point.

FAQs

Why crop a composition at all?

A frame that fits its content gives cleaner exports, smaller previews and tidier templates. It also helps when a design must match an exact output size.

Should I crop my only copy of a composition?

No. Duplicate the composition first, crop the copy and compare. That habit keeps your original framing safe if you change your mind later.

Does CropBox change my layers?

The tool is about the composition frame and its fit to the content. Review the result after running it, as with any utility that adjusts a comp.
