How to Sign a PDF Without Adobe Acrobat
You need to sign one document. Adobe Acrobat wants a subscription, a trial account, or a desktop install just to get there. If all you need is to put your signature on a form or agreement, here's a much more direct route.
Why Acrobat feels like overkill for a single signature
Acrobat is built to be a complete PDF suite — editing, forms, e-signature workflows with audit trails, team approvals. That's genuinely useful if you handle PDFs professionally at scale. But if you just need to sign one form today, working through a subscription or trial sign-up to get there is a lot of friction for a task that takes ten seconds once you're actually in the tool.

Step-by-step guide
- Open the Sign tool and drop in your PDF — no account prompt first.
- Draw your signature with your mouse or, on a touchscreen, your finger.
- Click "Use this signature" — it appears as a movable overlay on the page.
- Drag it into place and resize it using the corner handle; zoom in first if the signature field is small.
- Click "Place signature on this page", and repeat on other pages if needed.
- Click "Sign & Download" to get your signed file.
Frequently asked questions
Do I need to install anything?
No — it runs entirely in your browser, on any modern computer or phone.
Is this a real substitute for Acrobat's e-signature features?
For placing your own signature on a document you're signing yourself, yes. It doesn't replicate Acrobat's audit-trail e-signature workflows for routing a document to multiple people for approval — for a single signature on a single document, it covers exactly that.
Is my document uploaded to sign it?
No — the entire process, including drawing and placing the signature, happens locally in your browser. Your file is never sent to a server.
Can I reuse the same signature on multiple documents?
Each session starts fresh, so you'd draw it again for a new document — but within one document, you can place the same drawn signature on as many pages as you need.
