Redact PDF

·

Apply opaque blackout boxes and sanitize metadata to mask sensitive information.

100% On-Device

Recommended Workflow

Apply visual blackout masks over sensitive data and strip author/title metadata before sharing.

How to Use Document Privacy & Masking

Black out sensitive information, financial records, and confidential clauses with on-device visual masking and metadata sanitization. 100% private in-browser execution.

1

Upload PDF Document

Select or drag and drop the PDF containing confidential information into the redaction canvas.

2

Draw Redaction Areas

Click and drag over sensitive names, account numbers, or clauses to place solid blackout boxes.

3

Apply & Download

Select an optional label stamp (e.g., [REDACTED]), click Apply Redactions, and download your masked file with sanitized metadata.

Frequently Asked Questions

Can someone select or copy text hidden under a redacted box?
Drawing high-opacity blackout boxes visually covers content on screens and printouts. FolderBit also strips document metadata and overlapping annotations. In text-based PDFs without stream rasterization, specialized PDF debugging tools might still read raw content streams; we recommend reviewing exported documents or flattening pages for high-risk legal disclosures.
Can I redact multiple pages in the same session?
Yes. Step through any page in your document, draw redaction rectangles, and apply them all simultaneously with one click.
Are files uploaded to an external server during redaction?
No. Redact PDF operates 100% locally in your browser sandbox, guaranteeing complete document privacy.

Visual Masking & Blackout100% On-Device

Redact & Mask PDF Document

Apply opaque blackout boxes to visually cover sensitive clauses, numbers, and personal data, while stripping document metadata in your browser.

Privacy & Redaction Compliance NoticeThis tool applies opaque blackout rectangles and strips document metadata and annotations. Because underlying vector content and text streams may remain inspectable in specialized PDF debuggers without page stream flattening or rasterization, do not rely on visual overlays alone for high-risk legal disclosures without verifying flattened output.
