How to Sign a PDF Online
for Free (No Account)

The "print, sign, scan, email" ritual needs to die. It wastes paper, lowers document quality, and assumes you own a printer and a scanner. The modern way to sign a contract, offer letter or form is to add an electronic signature directly to the PDF — and you can do it for free, right in your browser.

This guide shows you exactly how to sign a PDF online, the difference between an electronic and a digital signature, and how to keep your private documents off other companies' servers while you do it.

Electronic Signature vs. Digital Signature

People use these terms interchangeably, but they're different:

• Electronic signature — a visual mark (a drawn or typed signature) placed on a document to show intent to agree. This is what most everyday agreements need, and what this guide covers.
• Digital signature — a cryptographic certificate that mathematically proves who signed and that the file wasn't altered afterward. It's used for high-assurance legal or government filings.

For the vast majority of documents — NDAs, rental agreements, offer letters, permission slips, vendor forms — a clean electronic signature is exactly what's expected.

Why Sign in the Browser (Instead of an eSign Service)

Big eSign platforms are powerful, but for a quick signature they're overkill: they make you create an account, upload your contract to their cloud, and often limit how many documents you can sign for free. For a private agreement, uploading it to a third party is also a privacy trade-off.

Signing in the browser with Raha Tools is different: there's no account, no watermark, and your file never leaves your device — the signature is drawn directly onto the PDF locally.

Step-by-Step: How to Sign a PDF

Here's the full process using the free Raha Sign PDF tool.

1. Upload your PDF

Open the Sign PDF tool and drag in your document. The first page opens in the signing view. Nothing is uploaded — it's read locally.

2. Create your signature

Choose Draw to sign with your mouse, trackpad or finger (great on touchscreens), or choose Type to enter your name in a handwriting-style font. Click "Use This Signature" when you're happy with it.

3. Place it on the page

Drag the signature to exactly where it belongs, and use the size slider to scale it. Navigate to a different page if you need to, and click "Add to this page". You can place your signature on multiple pages — useful for initialling every page.

4. Download your signed PDF

Click Download Signed PDF. Your signature is stamped onto the document as a crisp overlay, the rest of the file stays perfectly sharp, and there's no watermark.

Tips for a Professional-Looking Signature

• Draw slowly for a smoother line, or use the Type option for a consistent, clean look.
• Size it realistically — a signature roughly the width of the signature line looks most natural.
• Add the date if the form needs it (you can also use our PDF Editor to add a typed date next to your signature).
• Lock it down: after signing, you can password-protect the PDF so only the recipient can open it.
