Renumber It is a web-based tool that helps you insert new files into a numbered sequence. When you add a file at position #10 in a 1-80 sequence, it automatically generates commands to rename files 10-80 to 11-81. It runs entirely in your browser — your filenames never leave your device.
Simply paste your list of numbered filenames, specify where you want to insert new files, and we generate PowerShell commands that rename everything automatically. The entire process happens in your browser — your filenames never leave your device.
Absolutely. Renumber It processes everything locally in your browser. We never upload your filenames to any server, never access your actual files, and never store any of your data. It's 100% client-side processing.
Renumber It works for both Windows and MacOS. The web interface works on any modern browser.
No installation required. Renumber It is a web application that runs entirely in your browser. You just need PowerShell (built into Windows) to execute the generated rename commands.
