How to Fill and Sign a PDF with ModernPDF
Upload your PDF
Drag a PDF form, contract, or any document into the fill & sign tool. Your file never leaves your browser.
Fill in fields and add your signature
Click on form fields to type in your information. For non-interactive forms, click anywhere to add text. Draw your signature with your mouse or trackpad, type it, or upload an image of your signature.
Download your completed document
Save the filled and signed PDF. Your entries are flattened into the document so they can't be altered after download.
Types of PDF Forms
Interactive PDF forms have designated fields you can click and type into — these are the easiest to fill. Non-interactive forms (often scanned paper forms saved as PDF) don't have clickable fields, but ModernPDF lets you place text anywhere on the page, so you can fill these in too.
Adding Your Signature
ModernPDF offers three ways to sign: draw with your mouse, trackpad, or touchscreen for the most natural feel; type your name and choose from signature-style fonts; or upload a photo of your handwritten signature. All three produce a clean, professional result.
Legal Validity
Electronic signatures are legally binding in most countries. The US ESIGN Act (2000), EU eIDAS Regulation (2014), and similar laws in over 60 countries recognize electronic signatures for most business and personal documents. Some exceptions include wills, certain real estate transfers, and documents requiring notarization.
Frequently Asked Questions
Is an electronic signature legally binding?
In most jurisdictions, yes. The US ESIGN Act and EU eIDAS regulation give electronic signatures the same legal standing as handwritten ones for most purposes. Exceptions include wills, certain court documents, and contracts that specifically require notarization.
Can I fill non-interactive PDF forms?
Yes. Even if the PDF doesn't have clickable form fields, you can click anywhere on the document to add text. This works for scanned paper forms, government documents, and any static PDF.
Will my signature be saved?
ModernPDF processes everything in your browser. Your signature is not stored on any server and is discarded when you close the tab. For convenience, you can screenshot your drawn signature and upload it next time.
Can I add a date stamp?
Yes. Click anywhere on the document to add text, including the current date. You can position it next to your signature or in any date field on the form.
