Frequently Asked Questions About Signing PDFs
Is it safe to sign PDFs online with MyPDF?
Yes, absolutely. MyPDF processes all files entirely in your browser using JavaScript. Your PDFs and signatures never leave your device — nothing is uploaded to any server. This is the most private way to eSign documents online.
Is an electronic signature legally valid?
Electronic signatures are legally recognized in most countries under laws like the US ESIGN Act and EU eIDAS regulation for common business documents. For highly regulated documents (court filings, notarized documents), you may need a certified digital signature.
Can I add multiple signatures and text fields?
Yes. You can add as many text fields and signatures as you need. Each element can be positioned independently on any page. Just use the toolbar buttons to add more items and drag them into place.
Does this work on mobile devices?
Yes. The Fill & Sign tool works on any device with a modern browser — iPhones, Android phones, iPads, tablets, and desktop computers. On touch screens, you can draw your signature with a finger or stylus.
Can I sign a password-protected PDF?
If the PDF requires a password to open, you will need to unlock it first using our Unlock PDF tool. Once unlocked, you can sign it with this tool.
