About REJ files

A .rej file serves as a textual specific artifact generated when a software patch fails to apply cleanly to a source file. Typically created by command-line utilities like GNU patch or version control systems like Git, these files contain the specific "hunks" (fragments of code) that the software could not automatically merge because the target file differed too much from what was expected. The frustrating part for users is that operating systems rarely assign a default application to .rej files, treating them as unknown binary objects rather than simple text. This forces users to manually select a text editor every time they need to inspect the conflict. While the file itself is lightweight, its obscurity makes it difficult to share or archive in a standard documentation workflow. To verify the contents without altering your system associations, convert the file to TXT for universal compatibility, PDF for uneditable reporting of merge conflicts, or HTML to view the code structure in a browser.

Convert.Guru analyzes your REJ file, detects the exact format, and lets you read the text inside.

Users also converted GITIGNORE, GITKEEP and PATCH files.
