What is PDF Privacy Cleaner?
This tool scans and removes all hidden metadata from your PDF to protect your privacy before sharing. PDFs commonly embed author names, document titles, creation timestamps, software fingerprints, annotations, form fields, JavaScript actions, embedded files, XMP data streams, incremental updates, and more — information you may not want recipients to see.
How It Works in 3 Steps
Upload & Scan
Drop your PDF onto the uploader. Our deep scanner analyzes 19 metadata categories and shows you exactly what was found — all in your browser.
Review & Select
Browse organized categories, inspect each item, toggle which groups to clean, and optionally set replacement values for Document Info fields.
Download & Verify
Download your sanitized PDF along with a JSON cleaning report. Every removal is verified with a post-clean scan so you know it worked.
Privacy Protection
PDF metadata can leak your name, organization, software, and editing history. Our deep cleaner removes 19 categories of hidden data.
100% Browser-Based
Everything runs client-side using WebAssembly. Your files never leave your device — zero server uploads, maximum privacy.
Deep Scan Engine
Detects XMP streams, incremental updates, document IDs, form fields, annotations, JavaScript actions, embedded files, and more.
Verification Scan
After cleaning, the tool rescans the result to confirm every item was removed and the PDF is still valid.
Frequently Asked Questions
What metadata is removed?
The tool removes 19 categories including document info (title, author, etc.), XMP streams, annotations, form fields, JavaScript, attachments, bookmarks, document IDs, piece info, structure tree, mark info, output intents, viewer preferences, named destinations, optional content groups (layers), threads, page labels, and incremental update history.
Can I choose which categories to clean?
Yes! Categories are grouped by type — Document Info, IDs & Revisions, Structured Metadata, Interactive Content, etc. Toggle groups on/off, view each item's details by expanding the group, and use the search box to filter.
Can I replace metadata instead of blanking it?
Absolutely. When Document Info is selected for cleaning, fill in custom values for Title, Author, or Subject. The cleaner will use your values instead of leaving them blank.
Why remove metadata before sharing?
PDF metadata can reveal sensitive information like your name, editing software, document history, and revision data. Removing it protects your privacy and gives you a clean slate.
Will this corrupt my PDF?
No — the tool removes only metadata while preserving all page content, images, fonts, and structure. A post-clean verification scan confirms the result is valid.
Is my PDF uploaded to a server?
No! All processing happens entirely in your browser using the scanner engine. Your PDF never leaves your device.
