Are my files uploaded to a server?

No. TrulyFreePDF runs entirely in your browser - your file is opened and processed on your own device and is never uploaded, stored, or shared.

Which formats are available?

Plain numbers (1, 2, 3), "1 of N", and "Page 1", in six positions: any corner, top center, or bottom center.

Is this really free, or free "until you hit a limit"?

Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
