github-blob-link-copy is a free Chrome add-on designed to streamline the process of copying GitHub blob links. This tool enhances user efficiency by allowing users to select a range of lines directly from a blob page by clicking on the line numbers. Once the desired lines are selected, the user can easily copy the link using the standard keyboard shortcuts Ctrl + C or Cmd + C.

Additionally, if no specific range is required, users can bypass the selection step entirely. The add-on also supports a double-copying feature, enabling users to create permalinks effortlessly with a simple double-click. This functionality makes it a valuable tool for developers and users working extensively with GitHub.
