Questions & Answers

As answered by people managing VaultPDF Online.
  1. What makes VaultPDF Online unique?

    VaultPDF Online processes every file entirely inside the user's browser using JavaScript and WebAssembly โ€” nothing is ever uploaded to a server. Most "free" PDF tools quietly upload your files to process them remotely, which is a real risk for anyone handling contracts, medical records, or financial documents. VaultPDF removes that risk by design, not by policy.

  2. Why should a person choose VaultPDF Online over its competitors?

    Because the files never leave their device. Competitors like Smallpdf or iLovePDF process documents on remote servers, meaning the file is transmitted and briefly stored elsewhere. VaultPDF's local-processing architecture makes that impossible โ€” there's nothing to breach, subpoena, or accidentally retain, because the file simply never left the user's machine.

  3. How would you describe the primary audience of VaultPDF Online?

    Professionals who legally or ethically cannot risk uploading sensitive documents to third-party servers: lawyers handling client files, accountants processing financial statements, HR teams managing employee records, and healthcare staff dealing with patient paperwork.

  4. What's the story behind VaultPDF Online?

    VaultPDF started from a simple observation: most "free" PDF tools online quietly upload user files to remote servers to process them, even for something as simple as rotating a page. For professionals bound by confidentiality โ€” legal, medical, financial โ€” that's an unacceptable risk. VaultPDF was built to prove that PDF tools can be both free and genuinely private, by doing all processing locally in the browser.

  5. Which are the primary technologies used for building VaultPDF Online?

    JavaScript, WebAssembly (including a WASM build of QPDF for real AES-256 PDF encryption), PDF.js, and pdf-lib โ€” all running client-side, with no backend file processing.
