Questions
Does Watermark PDF upload the file?
No. The file stays in this browser. There is no account and no daily limit.
What does this tool refuse to do?
It will not recover a forgotten password, and it will not invent text that was never stored in the PDF. A file over 80 MB or 300 pages is stopped because this browser would run out of memory.
