reNamerX is a free desktop application for batch file renaming on Linux, macOS, and Windows. It applies text operations, case transformations, and sequential numbering to groups of files, and can process hundreds using consistent rules. A live preview shows the proposed filenames before changes are applied. More advanced options include regular expressions, date and time insertion, metadata such as creation date and size, and reusable rule presets. Users can select individual files or all files in a directory. Batch changes can be undone with Ctrl+Z, and the app also supports redo. Its interface has dark and cyberpunk theme options. The project is distributed under the MIT License, and the repository provides Windows MSI and EXE installer options. Windows installation requires Windows 10 or newer, a 64-bit operating system, at least 50MB of free disk space, and 4GB of recommended RAM. Building from source requires Node.js 16 or newer, npm or yarn, Rust and Cargo, and Git.
