How it worksPage 2 of 6
§ 02 · How it works

Three steps. No setup.

From a sensitive file to one you can share, without changing how the document looks.

STEP 1 Upload your document Scanned PDFs, native PDFs, Word files or images. Tilted scans, faded text and complex layouts are fine.
STEP 2 Rahul Mehta→Arjun Nair Re-Doc finds and treats sensitive data Names, IDs, accounts and addresses are replaced with realistic synthetic data or blacked out for good. A human review step makes sure nothing is missed.
STEP 3 Download the safe copy Same format you uploaded. PDF stays PDF, DOCX stays DOCX. Tables, headers and footers are kept.

Pick the one that fits your document

Not sure which? Start with the type of file you have. Each card shows exactly what the output looks like.

BEST FOR SCANNED DOCUMENTS
Redaction Sensitive data is blacked out permanently. Black boxes placed exactly over the text, even on poor scans. The original data is destroyed, not just hidden. Built for FOIA, legal discovery and compliance releases. Scanned PDF · DOCX · Images
BEST FOR TEXT-SEARCHABLE DOCUMENTS
Text replacement Sensitive data is swapped with realistic synthetic data. The same person gets the same synthetic name everywhere, so the document still makes sense. Stays searchable and editable. Useful for AI training, analytics and research. Native PDF · DOCX
BEST FOR TEXT + IMAGE DOCUMENTS
Multiple data types Text is replaced, images are blacked out. For brochures, SOPs and client documents that mix text and visuals. In one pass, Re-Doc replaces text and covers logos, stamps and signatures inside images. DOCX · Logos · Signatures

What our customers say

Teams handling sensitive documents use Re-Doc to make them safe to share.

From: Hub.xyz · YC S26About: a document data project
“Re-Doc was very helpful for a specific data project we ran for a frontier lab. We usually work with image, video and audio data, so documents were new territory for us, and Re-Doc helped us tackle it.”
