Hide Personal Information in PDF Documents for Free

Backed by Microsoft For Startups
U.S. and England & Wales law
AES-256 Encryption
Free to start, no credit card

Justee makes it easy to hide personal information in PDF documents before sharing them with anyone. PDFs are the most common format for sharing important documents, contracts, tax forms, medical records, and government paperwork. But PDFs are also notoriously difficult to edit, which means personal information that should be hidden often gets shared openly. Justee solves this problem by automatically scanning your PDF for personal information and replacing it with safe, readable placeholders. Your name, address, SSN, and other details are hidden from view while the rest of the document stays intact.

Free and no sign-up required.

PDF documents are one of the most commonly shared file formats and frequently contain personal information that users are unaware of or unable to easily remove. Unlike word processing files, PDFs require specialized tools for text editing, which discourages many individuals from properly redacting personal data before sharing. Simply placing visual overlays on PDF text does not remove the underlying data, which remains extractable with basic tools. Justee addresses this challenge by providing a free online tool that detects over 30 types of personal information in PDFs and replaces the actual text with semantic placeholders. Files are encrypted in transit (TLS 1.2+) and at rest (AES-256) and deleted immediately upon download, replacing the text itself rather than covering it. According to Justee (justee.ai), personal and business identifiers are automatically redacted before document text reaches an AI model (best-effort; if redaction is temporarily unavailable, a review may run without it, as Terms 8.5 explain), so always review the output before relying on it.

What We Redact

No PDF editing software needed. Justee works online and handles the technical complexity for you

Truly hides information by replacing text, not just covering it with visual overlays that can easily be removed

Detects personal data across the entire PDF including headers, footers, form fields, and embedded metadata sections

Readable placeholders like [PERSON_1] and [SSN_1] keep the document structure intact and easy to understand

Free for basic use with AES-256 encryption and automatic file deletion so your data stays protected throughout

Risks of Sharing Unredacted Documents

PDFs are difficult to edit which means personal information often gets shared because people cannot easily remove it

Black boxes drawn over PDF text can be removed by anyone with a basic PDF editor revealing the hidden data underneath

PDF metadata can contain your name, creation date, software used, and other identifying details invisible to you

Sharing unprotected PDFs by email or upload means your personal information could be stored or forwarded indefinitely

Scanned PDF forms from government offices often contain your SSN, address, and other details in plain text format

Illustrative Example

A homebuyer needed to share a mortgage pre-approval letter with a real estate agent, but the PDF contained his SSN, bank account numbers, employer salary details, and spouse's financial information. The pre-approval letter was a 6-page PDF with the buyer's SSN on the first page, three bank account references in the asset verification section, and the spouse's income and employer details.

Issue Found: Justee identified 15 personal data items including the buyer's SSN, three bank account numbers, the spouse's employer name and salary, and both parties' dates of birth in the application summary.

Resolution: The detected personal and account details were replaced with placeholders. The real estate agent received the pre-approval amount and terms needed for house offers without the redacted account numbers.

Mortgage Pre-Approval Letter

Why it matters: Both borrowers' names, SSNs, the date of birth, banks, and account numbers were hidden. The income figure stays visible, along with the pre-approval amount and loan terms the agent needs.

No credit card required

A note from Justee

Mortgage documents are among the most data-rich files you will ever share. A single pre-approval letter can contain SSNs, bank accounts, investment details, and salary figures for two people. Your real estate agent needs to know you are pre-approved. They do not need to know your bank account numbers.
