Delete sensitive data permanently. Our Redact PDF tool allows you to blackout text, images, and confidential sections of your document, ensuring they cannot be recovered by third parties.
What is Redaction?
Redaction is the process of censoring or obscuring part of a text for legal or security purposes. Unlike simply covering text with a black rectangle (which can often be removed), true redaction completely erases the underlying data from the file structure.
How it Works
You draw black boxes over the areas you want to hide. When you save, our tool "rasterizes" (flattens) the pages into images. This converts the editable text and original images into a single pixel layer, making the redacted information physically impossible to retrieve.

Frequently Asked Questions
Can the redacted text be un-hidden?
No. Because we convert the page to an image, the text layer is destroyed. There is no text left to reveal.
Will the file size increase?
Yes. Converting vector text to images usually increases file size. You can use our Compression tool afterwards to reduce it.
Can I change the redaction color?
Currently, we only support standard black redaction boxes.
