Stop Silent Privacy Leaks in PDF Documents

Every PDF document you create carries hidden forensic fingerprints. When you draft a contract in Word, design a pitch deck in Keynote, or export an architectural schematic from CAD, your software silently embeds invisible metadata:

  • Author Identity: Your full name, computer user profile, and department.
  • Operating Environment: Your computer hostname, operating system version, and exact PDF producer software.
  • Forensic Timestamps: The exact second the document was authored, edited, and exported.
  • XMP Tracking Streams: Extensible XML metadata packets containing digital asset IDs, prior filenames, and editing software history.

Sharing unscrubbed documents can be disastrous in legal disputes, investigative journalism, corporate negotiations, and double-blind academic reviews.

Commercial tools like Adobe Acrobat Pro and Sejda charge expensive monthly subscriptions to edit or purge metadata. Online converters force you to upload private files to their cloud servers.

AirPDF delivers a 100% Free, In-Browser PDF Metadata Editor & Deep Sanitizer. Inspect every hidden property, modify tags with precision, or execute a one-click forensic wipe in seconds with complete privacy.

Deep Sanitization vs. Custom Metadata Editing

  • One-Click Deep Sanitize (Anonymize): Instantly purges Author, Title, Subject, Keywords, Creator, and Producer tags. Deletes the entire /Metadata XMP stream and /PieceInfo private dictionaries from the PDF catalog, and resets or strips creation timestamps.
  • Custom Metadata Tuning: Update document titles, authors, keywords, and subjects to match professional publishing and indexing standards without affecting file formatting.

100% Client-Side Vector Integrity

Because processing occurs natively in your browser using WebAssembly and modern JavaScript, your document is never re-compressed, rasterized, or uploaded to any third party.

Frequently Asked Questions

What is PDF metadata and why is it a privacy risk? ▼

Whenever you export a document from Microsoft Word, Google Docs, Adobe InDesign, or scanner software, the PDF silently records hidden metadata. This often includes your personal name, operating system login, company name, revision history, exact creation timestamps, and unique document GUIDs. Sharing these files can leak confidential internal information.

What does 'One-Click Deep Sanitize' do? ▼

Deep Sanitize strips all standard document info tags (Title, Author, Subject, Keywords, Creator, Producer), wipes creation and modification timestamps, and permanently deletes the embedded XMP (Extensible Metadata Platform) stream and PieceInfo dictionaries from the PDF catalog.

Can I use this tool to anonymize manuscripts for blind peer review? ▼

Yes! Academic journals and conferences requiring double-blind peer review strictly mandate the removal of author names, affiliations, and document creation histories. AirPDF's deep sanitizer removes all author tags and digital traces instantly.

Will editing or scrubbing metadata alter my document layout or rasterize text? ▼

No. Only the invisible header metadata dictionary and XMP catalog stream are modified or removed. All page contents, fonts, vector drawings, high-resolution photos, and form fields remain 100% pristine and unaltered.

Are my confidential files uploaded to any cloud server? ▼

Never. All metadata extraction, dictionary inspection, and stream purging happen entirely inside your web browser's memory. Your files never leave your computer.
