Why JustSign?

🔒 Your PDF, your hands. Uploaded files are deleted after 24 hours. We don't share, sell, or mine them.
📱 Phone-friendly. Sign with your finger on mobile or your trackpad on a laptop. No app to install.
Draw or type. Sketch your signature freehand, or type your name and pick from six cursive fonts.
🆓 Free, forever. No trial, no signup, no credit card. We make money from teams that send signing requests to others.
📄 Real PDFs. The signature is burned into the file, not laid over a preview image. Recipients see exactly what you signed.
Under a minute. Most one-page forms take 30 seconds: upload, sign, download.

Common questions

Is this really free?

Yes, with no asterisks. JustSign's business is sending signing requests to other people — that's the paid product. Self-signing a PDF in your own browser costs nothing, doesn't require an account, and isn't on a trial. We don't watermark the output or limit what you can do with the signed copy.

What happens to my PDF?

It gets uploaded to our server so the editor can show it to you, and it's automatically deleted after 24 hours. We don't read it, don't share it, and don't train any AI on it. If you'd rather not upload at all, you can still print-sign-scan — but the whole point of this tool is to skip that.

Why only 3 pages?

The free self-sign flow is sized for the typical "sign this and send it back" case — receipts, permission slips, single-page agreements. For longer documents, packets, or anything you'll sign more than once, create a free JustSign account and use the full editor (which has signer slots, templates, audit trails, and unlimited pages).

Can I add fields besides my signature?

Yes — text, date, and signature fields are all supported. Click the field type in the toolbar, then click where on the PDF it should go. Fill in the value as you place it, or drag it around if you don't get it right the first time.

Is a typed-name signature legally binding?

In most jurisdictions, yes — both the U.S. ESIGN Act and the EU eIDAS regulation recognize electronic signatures, including typed names, as legally equivalent to handwritten ones for the vast majority of agreements. If the document you're signing requires a specific notarization or a wet signature (some real-estate, court, or estate-planning documents), check with whoever sent it to you first. For everyday contracts and forms, type-or-draw is fine.

Does this work on a phone?

Yes. Upload the PDF, tap the signature button, draw with your finger. The editor is designed to work on small screens — pinch to zoom in on a particular field if you need more precision while placing it.

I sign things like this all the time. Should I just create an account?

Probably yes. A free JustSign account lets you save the documents you sign, re-use templates if the same form keeps coming back, and (if you upgrade) send signing requests to other people. Sign up takes 30 seconds — but if you just need to sign this one PDF right now, no need.
