The Security Benefits of Client-Side PDF Tools

By VexDocs Team Updated Dec 2025

Most online PDF tools upload your files to a remote server to process them. This creates a privacy risk. VexDocs is different.

What is Client-Side Processing?

Client-side means the code runs on your device (in your web browser), not on our servers. Your file is never sent over the internet.

Key Benefits

  • 100% Privacy: Since the file never leaves your computer, no one can intercept or store it.
  • Speed: No upload or download time. Large files process instantly.
  • Offline Capability: Once the page loads, you can use the tool even without an internet connection.

VexDocs uses advanced technologies like WebAssembly and modern JavaScript APIs to bring desktop-class performance to the web.
