Deep Sanitization
Byte-Level Removal
Many tools only cover text with a black rectangle. DocuStitch deletes the character data from the PDF stream entirely, making it impossible to "copy-paste" or use OCR to recover it.
Metadata Scrubbing
Hidden properties like author, creation date, and version history can leak info. Our engine scrubs the PDF metadata as part of the redaction pipeline.
Securely Redact Sensitive Information from PDF Documents Permanently
Redacting sensitive information—such as social security numbers, medical diagnoses, or trade secrets—is a critical step before making a document public. However, many "redaction" tools on the market are deceptive. Some merely place a black rectangle over the text, leaving the original data searchable and retrievable via a simple copy-paste or OCR scan. DocuStitch provides a true, byte-level sanitization solution.
Our Redact PDF tool uses a high-performance WASM-based sanitization engine. When you mark an area for redaction, our engine doesn't just 'hide' the content; it rewrites the PDF’s internal byte-stream, permanently deleting the targeted text objects and image data from the file structure. This process happens entirely within your browser's RAM, ensuring that the unredacted version of your document never leaves your machine.
Furthermore, our engine performs a deep metadata scrub, removing hidden properties like authorship and revision history that can inadvertently leak sensitive context. This makes DocuStitch the professional choice for legal discovery, FOIA responses, and corporate privacy compliance.
Byte-Level Stripping
