Professional PDF tools built for lawyers, accountants, HR, and healthcare professionals. Your files never leave your device — not a promise, an architectural fact.
Every tool runs entirely in your browser. Your documents are never uploaded, transmitted, or stored on any server.
Reduce file size while maintaining quality. No upload, no limits, instant results.
Combine multiple PDFs into one. Drag and drop to reorder pages before merging.
Extract specific pages or split by range. Perfect for isolating contract sections.
Add AES-256 password encryption. Industry-standard security for sensitive documents.
Detect sensitive data before sharing — card numbers, emails, IDs. A VaultPDF exclusive.
Generate downloadable proof that your document was processed with zero server contact.
Traditional PDF tools upload your files to remote servers. VaultPDF processes everything locally in your browser.
Drop your PDF into the tool. The file stays in your browser memory — never transmitted anywhere.
Our engine runs entirely in your browser. Watch the live proof: 0 bytes sent to any server.
Your processed file is ready immediately. No waiting, no email, no account required.
When your documents contain client data protected by law, "we delete files after 24 hours" is not enough.
NDA-safe document handling. Merge case files, redact privileged information, compress discovery documents.
Process tax returns, financial statements, and audit documents without regulatory exposure.
HIPAA-compatible by design. Patient records and lab results stay on your device.
Employment contracts, payroll data, and background checks — zero third-party exposure.
After processing any PDF, download a verifiable certificate proving that your document was handled with zero server contact. Attach it to compliance records, client files, or audit trails.
