PDF Redact
Permanently redact sensitive information from PDFs. Each page is converted to an image — the original text layer is completely destroyed.
Secure Redaction Method
Each PDF page is rendered as a high-resolution image. Your redaction boxes are burned into the image. The result is a new PDF with no original text layer — making data recovery impossible.

Frequently Asked Questions
Can someone 'un-redact' my file to see what's underneath?
No. Because we convert the page into an image, the original text characters no longer exist in the file. It is physically impossible to 'remove' the black boxes.
Does this remove hidden metadata like 'Author' or 'Location'?
Yes. Our secure redaction process creates a fresh PDF from scratch, effectively stripping away all original hidden properties and revision history.
Is my original file uploaded to your servers?
Never. This is a 100% serverless utility. Your document stays in your RAM and is processed locally. We never see your data.
Can I redact images and signatures as well as text?
Yes. Since you are selecting areas on a canvas, you can redact anything—text, photos, logos, or handwritten signatures.
Will the redacted PDF be searchable?
The areas you don't redact will still be visible, but since the page is now an image, the text is no longer 'selectable' or 'searchable' by default, which is the highest level of security.
Protect your privacy with the most secure PDF Redaction tool available online. Unlike basic editors that simply hide text behind black boxes, our 'Secure Redaction' engine physically destroys the underlying data. By rendering each page into a high-definition image and 'burning' your redactions into the pixels, we ensure that no software, hacker, or search tool can ever recover your hidden information. Process your sensitive legal, medical, or financial documents entirely on-device with zero server uploads.
