PDF tools that stay on your device.

No document uploads. No accounts. Just fast, private PDF processing in your browser.

Built with privacy by design.

No server uploads

VaultPDF processes the documents you select inside your browser. The application does not upload their contents to a Mesanix Labs PDF-processing service.

No file storage

Selected documents are kept in browser memory for the working session, not in a VaultPDF document store. Reloading or closing the page clears that working session.

No accounts required

Core tools work without registration, sign-in, or a user profile. Open a tool, work locally, and download the result to your device.

Private PDF tools that run in your browser

VaultPDF helps you merge, split, compress, convert, arrange, watermark, and sign PDF files without sending documents to a server.

How it works

  1. Choose the PDF tool you need.
  2. Work with your files locally in the browser.
  3. Download the finished file directly to your device.

Common questions

Does VaultPDF upload my files?

No. Core PDF workflows run locally in your browser, so your documents stay on your device.

Do I need an account?

No. VaultPDF tools are designed to work without sign-up, accounts, or document storage.
