About this guide
In 2027, every file you share carries a digital fingerprint that could compromise your business or your clients. That fingerprint is metadata — the hidden record of who created the document, on what device, with which software, and what changed along the way. Most people never think to check it, and most "free" tools never tell them.
The Document Security Manual provides the exact steps for metadata scrubbing, secure storage, and local-first document processing using tools like PDFRange. It's built for people who send contracts, invoices, quotes and client records every day — and who are tired of hoping the recipient never opens the file properties.
You'll leave with a repeatable protocol: scrub before you send, store on devices you control, and audit your filing cabinet on a schedule. It's the difference between "we share files" and "we share files safely".

From the guide
"Before you send any file, run the one-question test: if this document were opened by a stranger, what would it tell them about you? If the answer is anything more than the content itself, you haven't finished the document yet."
Frequently asked questions
What is metadata and why is it dangerous?
Metadata is hidden data inside every file — author names, organisation, timestamps, software used and edit history. When you share a PDF without scrubbing it, you can unintentionally expose internal details about your business or your clients.
How do I remove metadata from a PDF?
Use a metadata cleaner that processes the file locally in your browser, such as PDFRange's Metadata Cleaner. Scrub author fields, timestamps and hidden layers, then re-save before sharing the document.
Is it safe to use free online PDF converters?
Server-side converters upload a copy of your file to their infrastructure, where it can be logged, retained or breached. For sensitive business documents, only browser-side tools that never upload your file are truly safe.
What is local-first document processing?
Local-first means the processing code runs in your browser and your file never leaves your device. It is the only architecture where you retain full control over sensitive documents at every step.
How often should I audit my documents?
The manual includes a 30-day document audit: review what you store, what you share, and whether metadata is being stripped consistently. Quarterly audits catch leaks before they become incidents.
