Before sharing a PDF that contains personal information — names, addresses, phone numbers, ID numbers, or financial data — you should redact any information not intended for the recipient. Here is how to do it properly and for free.

Go to pdfeditor.onl/pdf-studio and upload your PDF.
Select the Eraser tool. Paint over each piece of personal information: names, addresses, contact details, ID numbers, financial figures. The eraser permanently replaces the area with a white paint layer.
Tip: After erasing, use the Annotation tool to draw a solid black rectangle over the same area for the standard black-bar redaction appearance.
Zoom in to 200% and systematically review every redacted area. Ensure no personal information is visible around the edges of the redaction.
