PDF Redact

There are countless situations in business and daily life where you need to safely hide sensitive information in PDFs — personal details, addresses, phone numbers, social security numbers, bank account numbers, and more. Simply changing text color to white is not secure, as the data can still be extracted via copy and paste.

This tool lets you specify a page number and coordinates (as percentages) to draw opaque black rectangles over the specified areas, permanently hiding the information. All processing runs locally in the browser using pdf-lib, so your confidential data is never uploaded to any server. You can specify multiple redaction areas at once, spanning different pages.

Coordinates use a percentage system (0–100%) based on the bottom-left corner of each page, making it intuitive to position redactions regardless of page size. An automatic overlap detection feature warns you when areas overlap or touch, preventing accidental duplicate redactions.

Ideal for government information disclosure requests, partial contract redactions, anonymization under privacy laws, masking confidential sections of internal documents, and legal compliance workflows.
