Client-side PDF redaction with privacy by design

DocClean is a browser-based redaction tool for removing personal data from PDF documents. PDF rendering, OCR and redaction all run locally in your browser memory — your contracts, UK CoS letters, bank statements, tenancy agreements and payslips never leave your device.

After OCR, DocClean detects patterns such as names, dates of birth, national insurance numbers, email addresses, phone numbers, full addresses, postcodes and financial account numbers. Your chosen profile controls which items are automatically hidden versus flagged for manual review.

Profiles for GDPR, CCPA and social sharing

GDPR-safe (EU/UK): aggressive removal of direct identifiers, contact details, addresses and financial IDs.
CCPA/CPRA-lite: focuses on information linked to a consumer or household, aligned with California privacy rules.
Social sharing: hides obvious doxing vectors such as faces, licence plates and direct contact channels.
Custom: choose your own rules for which PII categories are auto-hidden or flagged.

Typical use cases & responsibilities

Visa/immigration bundles while hiding NI numbers, home addresses and contact details.
Sharing HR packs, payslips or offer letters internally without exposing personal data.
Creating realistic examples for documentation or open-source repos without leaking real info.

DocClean helps you reduce risk, but you remain the data controller. Always check the exported file before you send it.

How to redact PDFs safely

Redaction should remove sensitive information from the exported file — not just cover it visually. Start by choosing a profile (for example GDPR-safe), run detection, then review every page. Add manual blocks for signatures, photos, handwritten notes, barcodes and QR codes.

What to redact (common examples)

Email addresses, phone numbers, and postcodes
National Insurance numbers, passport numbers, and reference IDs
Bank account details (account number, sort code, IBAN)
Signatures, QR codes, and barcodes that can encode identifiers

Verify your export

After exporting, open the exported PDF and run a quick check: search for your surname, postcode, or ID fragments. Try copy/paste around redacted areas in a PDF reader. If the sensitive text still appears in search or copy/paste, redo the redaction using a safer method.
