Signing a PDF document used to require printing, signing by hand, scanning, and emailing back. It was slow, messy, and pointless. Today, you can sign any PDF online in under 60 seconds — for free, without downloading any software. Here's exactly how to do it with Signpace.

What You'll Need

No account required for basic signing. No downloads. No watermarks. No credit card. Sign up to 3 documents per month for free.

Step-by-Step: How to Sign a PDF Online

Step 1: Open Signpace and Upload Your PDF

Go to signpace.com and click "Sign Documents" or navigate directly to the sign page. Click the upload area or drag your PDF into the drop zone. Signpace accepts PDFs up to 25MB. Most standard contracts and agreements are well under that limit.

Step 2: Create Your Electronic Signature

You have three options for creating your signature:

  1. Draw it: Use your mouse, trackpad, or finger (on touchscreens) to draw your signature. Takes about 10 seconds and looks natural.
  2. Type it: Type your name and pick from one of Signpace's signature fonts. Instant and clean.
  3. Upload it: Already have a signature image (PNG or JPG)? Upload it directly.

Step 3: Place Your Signature on the Document

Click anywhere on the PDF page to place your signature. You can drag it to the exact position you need and resize it using the corner handles. Navigate between pages if your document has multiple pages.

Step 4: Download the Signed PDF

Click Download to save the signed PDF to your device. The signature is embedded directly in the PDF — no extra software needed to view it, and it looks identical to a physically signed document.

Tips for Signing PDFs Online

Can I Sign PDFs on My Phone?

Yes. Signpace works on all modern smartphones and tablets through the browser. The drawing tool works with your finger. No app download required. Just visit signpace.com from your mobile browser and follow the same steps.

Is This Legally Valid?

Yes. Electronic signatures created with Signpace are legally binding under the U.S. ESIGN Act, UETA, and EU eIDAS Regulation. They carry the same legal weight as a handwritten signature for contracts, NDAs, employment agreements, real estate offers, and most other business documents.

Need to send the PDF to someone else for their signature? Upgrade to the Starter plan ($12/month) to send signing links and collect e-signatures from multiple parties.
