Why Use PDFBro to Sign PDFs
Frequently Asked Questions
Is an electronic signature from PDFBro legally valid?
Yes. E-signatures created with PDFBro are valid under the ESIGN Act (US), eIDAS (EU), and similar laws globally. An electronic signature is legally binding as long as both parties intend to sign. PDFBro's signatures meet the standard requirements for most contracts, NDAs, and agreements.
Can I draw my actual handwritten signature?
Yes. Use your mouse, trackpad, stylus, or touchscreen to draw your signature exactly as it appears on paper. PDFBro captures the natural strokes for a realistic hand-signed look. Works especially well on iPads and touchscreen laptops.
Does the signature tool work on my phone?
Yes. The sign PDF tool is fully responsive — works on iPhone (Safari), Android (Chrome), and tablets. Touchscreens make drawing signatures even easier. Sign documents on the go without downloading an app.
Will my signed PDF have a watermark?
Never. PDFBro adds zero watermarks to any signed document. Your PDF downloads clean and professional — just like a desktop PDF application, but free and browser-based.
How does PDFBro's signing compare to DocuSign or Adobe Sign?
PDFBro provides the core signing functionality — draw, type, or upload a signature and place it on a PDF — completely free. DocuSign and Adobe Sign add workflow automation, audit trails, and multi-party routing for paid business plans. For individual signing needs, PDFBro covers everything you need at zero cost.
Can I sign multiple pages or multiple documents?
Yes. Place your signature on any page of your PDF. For multi-page documents, you can sign each page individually. There are no daily limits — sign as many documents as you need, all free.
