Sign PDF FAQ
Is an electronic signature legally valid?
In many countries a simple electronic signature is valid for most contracts, but rules vary. Check requirements for official or regulated documents.
Can I put my signature on every page?
Yes. Turn on 'Place on every page' to stamp the same position across the whole document.
Are my files uploaded to a server?
No. pdfy processes your files inside your browser using your own device. Local tools do not upload documents. If you choose Save draft, that draft is stored only in this browser. You can confirm it in your browser's network panel: no file is ever sent.
Is it really free? Are there limits?
Yes, it is free with no sign up, no watermark on your output and no daily task limit. Because your device does the work, the only practical limit is your device's memory.
