I built a document converter that never uploads your files

Every time you use an online PDF converter, your file travels to a server somewhere — processed by a company you don't know, stored temporarily on hardware you don't control.

For a random meme? Fine. For a payslip, a contract, or a medical document? That's a real privacy problem.

What I built

ConvertiZen is a document converter that runs 100% in the browser using WebAssembly and modern JS APIs. Your file never leaves your device. Ever.

Verify it yourself: open DevTools > Network tab > run a conversion. Zero outgoing requests containing your file data.
