What you get on GitHub

Why it helps on GitHub

Bug reports and PRs on GitHub lean on screenshots, which render small in the thread. Ultra Zoom enlarges attached images on hover so you can read a screenshot of an error or a UI without opening it in a new tab.

How to use Ultra Zoom on GitHub

  1. Install Ultra Zoom for Chrome or Firefox.
  2. Open github.com — GitHub works on the free tier right away, no setup required.
  3. Hover any image to see it at full resolution. Use ← / → for galleries, Z for theater mode, and ? to see every shortcut.
