Which text tool do you need?
For writing, start with the word counter and the case converter. To clean data, use remove duplicate lines and the JSON formatter. For development work, there are Base64, URL encoding, the UUID generator and the timestamp converter. For security, try the password generator and the file hash checker.
Is my text private?
Yes. The text tools work entirely in your browser. Even so, avoid pasting real passwords, API keys or private data into any online tool you do not control.
