GitHub PR Whitespace Hider is a browser extension designed specifically for users of GitHub who want to enhance their code review experience. This free tool automatically hides whitespace changes in pull request diffs, allowing developers to focus on the essential code changes without the distraction of unnecessary whitespace.

While GitHub has implemented features to remember whitespace settings for individual pull requests, user-level settings for all PRs are still lacking. This extension addresses that gap, providing a seamless way to improve the readability of code reviews across the platform. By simplifying the visual presentation of diffs, it supports more efficient collaboration among developers.
