How to Hide Sensitive Information Before You Share a File

You open the page, put your text or file in, press Transform, check the result, and download it. Private details such as email addresses, phone numbers, card numbers, passwords, and secret keys are swapped for harmless labels like [EMAIL_1]. Everything happens inside your own browser tab.

Why This Exists

If you test software or manage a product, you constantly send things to other people: a bug report with an attached log, a screenshot of a customer problem, a contract, an ID card photo. Those files often contain details that should not leave the team: a customer's name, a phone number, a login token, a password that scrolled past in a terminal.

Most "redaction" websites ask you to upload the file first. That means you hand over the very secret you wanted to protect. This tool does the opposite: it runs on your computer, so the file never travels anywhere.
