Frequently asked questions
Is PDeF really free?
Yes. Filling, signing and downloading are completely free, with no account and no watermark. The tool is funded by ads on the info pages.
Is my PDF uploaded to a server?
No. All processing (rendering, filling, signing, export) happens locally in your browser. Your file never leaves your device.
Is the signature legally valid?
You create a simple electronic signature (SES). That is sufficient for many everyday documents such as forms and confirmations. Contracts that legally require written form need a qualified electronic signature (QES).
Does it work on a phone?
Yes. The interface is optimised for smartphones, and you can draw the signature on your phone via QR code while editing on the desktop.
Which files are supported?
PDF files, including scanned forms without interactive fields: just drag text boxes, check marks and your signature where they belong.
