File Name Cleaner - Format Bulk Text

Clean and standardize messy file names instantly. Our free File Name Cleaner replaces spaces with hyphens, removes special characters, and formats text locally in your browser.

What is the File Name Cleaner?

When uploading images to a web server or organizing a digital archive, file names containing spaces, capital letters, or special characters (like % or &) can break URLs and cause server errors. The File Name Cleaner automates the tedious process of renaming. You can paste a list of messy file names, and the tool will instantly convert them into a web-safe format (e.g., 'My Photo!.jpg' becomes 'my-photo.jpg'). Because you might be working with sensitive corporate file structures, all text manipulation occurs locally on your device.
