I built a small tool called GitShrink to solve a simple problem: making videos small enough (<10MB) to upload to GitHub.

It runs entirely in the browser, so nothing is uploaded anywhere.

It’s a small, local-first tool with no accounts, no tracking, and no backend.

Use cases:

README demo videos Small product demos Screen recordings for GitHub

Feedback is welcome.
