Why is iLovePDF or Smallpdf blocked by my company firewall?

iLovePDF and Smallpdf upload your files to external servers, which triggers corporate DLP policies and firewall rules (such as Zscaler). ExactPDF processes files entirely in your browser — nothing is sent to any server, so it passes corporate firewalls and restricted networks.

Yes. ExactPDF runs 100% in your browser using WebAssembly. No files are uploaded to any server, so corporate DLP policies, Zscaler, Cisco Umbrella, and other proxy filters have nothing to block.

How do I chat with a PDF without uploading it?

Use ExactPDF's AI Chat with PDF tool. The AI model runs locally in your browser using WebAssembly — your file is never sent to a server. Ask questions about any PDF privately and offline.
