Hide personal information
Finds and hides things shaped like phone numbers, emails, Korean resident numbers, cards, bank accounts, license plates and detailed addresses. Detection is not perfect — names, workplaces and schools have no fixed shape, so read the text once more before posting. Nothing is sent to a server.
Send this text to another tool
The text is not put in the address; it moves only inside this browser. Nothing is sent to a server.
FAQ
Text copied from a PDF is broken into short lines.
Choose "Keep paragraphs, join inside them" under Remove line breaks to keep paragraph breaks and only join the broken lines.
How is sorting ordered?
Dictionary order that reads numbers by value, so "file2" comes before "file10", and mixed scripts sort naturally.
Is my text stored?
No. Everything runs in your browser and nothing is sent anywhere.
