Full-stack monitoring for errors, metrics, and logs

I built Secure-Merge because I was frustrated with existing PDF tools that force you to upload sensitive files to a server, add watermarks, or limit how much you can use them. For legal, financial, or even personal documents, that always felt risky and inconvenient. What makes Secure-Merge different is that it runs 100% in your browser — your files never leave your device. That means: No uploads → complete privacy and control. No tracking or ads → a clean, distraction-free experience. No limits → merge as many PDFs as you want, watermark-free. I’m most proud that we deliver a tool that gives people peace of mind: you can finally merge PDFs instantly without worrying about data exposure. It’s simple, secure, and fast — exactly what a PDF tool should be. Would love to hear your feedback and ideas on what features you’d like to see next!

Small update from the last week:

• Added anonymous Plausible events (no cookies, no IDs) to improve UX quality.

• Clarified privacy on the page: “All processing happens in your browser.”

• Focused testing on Microsoft Edge (lots of Windows users).

If you tried Secure-Merge and hit any edge cases (pun intended), I’d love to fix them. 🙌
