Username Cleaner - Sanitize Your Username
Clean and sanitize a username (or list of usernames) by stripping spaces, restricting to an allowed character set, enforcing a max length, and optionally lowercasing everything.

How to Use the Username Cleaner
Type or paste the username (or a list of usernames, one per line) you already have in mind. Choose which extra characters to allow beyond letters and numbers — underscore, period, and hyphen are the most common platform-allowed extras — set a maximum length, and optionally force everything to lowercase. The tool strips spaces, removes any character outside your allowed set, and truncates to your chosen length so the result fits common username formatting rules used across most sign-up forms.
Example
Typing John Smith! 1999 with underscore, period, and hyphen all allowed and a max length of 15 produces JohnSmith1999. Turning on the lowercase toggle instead produces johnsmith1999.
Common Use Cases
- Turning a full name or phrase into a username that passes a signup form's character restrictions.
- Cleaning up a batch of usernames pasted from a spreadsheet before a bulk account import.
- Enforcing a consistent lowercase, length-limited username format across a team or organization.
FAQs
- How is this different from the Username Generator or Random Username Generator? Those two tools CREATE a brand-new username for you — one builds suggestions from a keyword, the other generates a fully random one. This Username Cleaner does the opposite job: it takes a username you already have in mind and sanitizes it to fit common platform formatting rules, without inventing anything new.
- Why would a character get removed? Most platforms only allow letters, numbers, and a small set of punctuation like underscore, period, or hyphen. Any other character — spaces, emoji, accented letters, symbols — is stripped out because it would likely be rejected by a signup form.
- Does it check if the username is actually available? No — this tool only reformats the text you provide; it doesn't check any platform to see whether that username is already taken.
