Frequently Asked Questions (FAQs)

What is True Redaction vs a Black Rectangle?

Drawing a standard black box merely places a visual layer on top, leaving underlying text and images completely extractable. True redaction physically erases the underlying image pixels and strips text operators from the PDF stream so content can never be recovered.

Can redacted information be recovered by copying or search?

No. IMGFixy's true redaction engine sanitizes the internal text content stream. In-memory validation scans the resulting PDF to guarantee that zero search matches or selectable glyphs remain.

Are my confidential documents uploaded to any server?

No. The entire redaction and security validation process runs 100% inside your browser using WebAssembly and client-side JavaScript. Your sensitive documents never leave your computer or phone.

How does Search & Redact work?

Search & Redact builds an index of all text strings across the document, identifies exact coordinates, and allows you to review and redact matching occurrences across the entire file in one click.

What smart patterns can be automatically detected?

You can automatically scan for Email addresses, Phone numbers, Credit card numbers, Social Security / Government IDs, Dates, and custom Regular Expressions with full user review before applying.

Does redacting a PDF invalidate digital certificate signatures?

Yes. Because true redaction modifies the internal document bytes to physically remove sensitive information, any existing cryptographic digital signatures will be altered. The tool provides a clear warning if a signature is detected.

Is document metadata sanitized?

Yes. The sanitization options automatically strip hidden document metadata (Author, Title, Subject, Producer, Creator, and XMP metadata packets) as well as embedded JavaScript actions.

Can I redact entire pages or page ranges?

Yes. You can redact the current page, all odd pages, all even pages, or specific page ranges with a single click.

Does this tool comply with GDPR, HIPAA, and FOIA standards?

Yes. By physically removing sensitive data from the file format and generating a downloadable Technical Redaction Audit Report, it satisfies strict data privacy and legal disclosure requirements.

Can I use this tool on mobile phones and tablets?

Yes. The workspace is fully responsive with touch drag gestures, pinch zoom, and fine position controls optimized for touchscreens and desktop keyboards.
