FAQ
Why compare PDF tools at all?
Most "free" PDF sites upload your file to a server, cap daily tasks, or push a subscription. Comparing them on privacy, limits and price helps you pick one that won't surprise you.
Is PDFzen actually free?
Yes. Every tool here runs in your browser — the file never leaves your device, there's no signup, and there are no daily caps. We cover costs with ads, not paywalls.
