How to Safely Redact & Black Out Sensitive Information Before Sharing
Whether you are renting an apartment, applying for a freelance contract, opening a trading account, or selling a car, you are frequently asked to upload a photo of your Driver's License, Passport, Bank Statement, or Utility Bill.
Sending unredacted identity documents exposes you to identity theft, credit fraud, and address tracking. ToolsKit's Privacy Blackout Studio enables you to permanently destroy sensitive numbers, signatures, and barcodes directly in your web browser before sending.
The Smartphone Markup Pen Danger
Millions of people use the default “black marker” or “highlighter” tool in their iPhone Photos or Android markup app to scribble over bank numbers and driver's license IDs. This is dangerous: those tools often have 90% opacity or save the drawing as a separate editable layer. Any recipient can open the image, max out the brightness and contrast, or remove the annotation layer to read your private information in seconds.
