How to Sign a PDF Online: A Step-by-Step Guide
Signing a PDF used to mean printing, signing by hand, scanning, and re-attaching. Today you can do the entire process online in under two minutes — no account required, no software to install. Here is exactly how to do it with PDFSigned.
Why Sign PDFs Online?
Electronic signatures are legally binding in most countries under frameworks like the U.S. ESIGN Act and the EU eIDAS regulation. Signing online is faster, cheaper, and leaves a cleaner audit trail than wet-ink alternatives. You avoid the printer-scanner loop entirely and can complete contracts, lease agreements, NDAs, and authorization forms from any device.
PDFSigned supports multi-page documents, three signature creation methods, and direct email delivery — so you can go from raw document to signed and sent in a single workflow.
What You Need
- A PDF file to sign (up to 50 MB)
- A modern web browser — Chrome, Firefox, Safari, or Edge
- No account required to sign and preview. You pay per export when you need the finished PDF.
Step-by-Step: Sign a PDF in Four Steps
Go to pdfsigned.com and click Start signing. Drag and drop your PDF onto the upload zone or click to browse your files. Your document will open in the signing editor with all pages visible.
Choose how to create your signature: draw it with your mouse or finger, type your name in a signature font, or upload an image of your handwritten signature. Your signature is saved for the session so you can reuse it on multiple pages.
Click the page and drag your signature to exactly the right position. You can resize it, reposition it, and add it to multiple pages. Add initials, date fields, or text annotations as needed.
When you are done, click Export. You can download the signed PDF directly, send it to an email address from within the app, or save it to your Vault if you have an account. Pay per export — no subscription is required.
Tips for a Valid Signature
- Use consistent placement. Sign on the designated signature line when one is present. Courts and counterparties recognise signatures placed in the correct field.
- Add a date field. Including the date alongside your signature strengthens the evidentiary value of the document.
- Keep the original PDF. Save a copy of the signed PDF in a safe location. PDFSigned's Vault feature can store it for you.
- Check jurisdiction requirements. Most everyday contracts are fine with a standard electronic signature. For highly regulated documents (e.g. real estate deeds in some states), verify requirements with a legal professional.
Common Questions
Is an electronic signature legally valid?
Yes. In the U.S., the ESIGN Act (2000) gives electronic signatures the same legal standing as handwritten signatures for most commercial documents. In the EU, eIDAS applies. Some document types have specific exceptions — consult your legal counsel if unsure.
Can I sign a PDF on my phone?
Yes. PDFSigned works on mobile browsers. The draw-signature option is particularly easy on a touchscreen — trace your signature with your finger directly in the browser.
What if I need multiple signers?
You can export the signed PDF and send it to the next signer, who can open and sign it in the same way. Each person adds their signature to the document before passing it along.
