Sign PDF Online Free
Sign PDF lets you sign a PDF online free, right in your browser — draw your signature or type it in a cursive font, drop it anywhere on the page, and download the signed file. There is no account, no sign up, and no Adobe required, and nothing is uploaded: your document is signed entirely on your own device.
Got a form or contract to sign? It takes about a minute.
Use the free PDF signer →What is Sign PDF?
Sign PDF is a free, browser-based tool for adding your signature to a PDF document. Instead of printing a page, signing it by hand, and scanning it back in, you open the PDF here, add a signature, and save a finished copy in seconds. It is built for the everyday cases — a lease, a permission slip, an offer letter, a tax or HR form — where you just need a signature on the page without buying software or creating yet another account.
Because it runs as a private, installable web app, you can keep it on your phone's home screen and sign documents on the go. It works offline after the first visit, so a signature is always one tap away.
How to Sign a PDF Online Free
The whole process runs in your browser tab — nothing is sent to a server — and it takes three short steps:
- Open capsuletools.app/sign-pdf/ and choose your PDF (up to 50 MB)
- Draw your signature with a finger or mouse on the signature pad — or switch to the Type tab to type your name in a cursive font. Pick black or blue ink.
- Your signature appears on the page as a movable box — drag it into place and use the corner handle to resize it
- On a multi-page PDF, flip to the page you want to sign before placing the signature
- Tap Save Document to download the signed PDF (
[filename]-signed.pdf)
Only the signature image is added — the document's original text, fonts, and pages are left exactly as they were.
Sign PDF Without Adobe
To sign a PDF, people usually reach for Adobe Acrobat — but the fill & sign tools sit behind a paid Acrobat plan, and the desktop app is a heavy install. This tool needs none of that. It opens your PDF, lets you sign the PDF without Adobe by drawing or typing, and digitally signs the PDF online free using a real PDF editor in your browser. No Acrobat, no Pro subscription, no install.
That means you can electronically sign a PDF without Adobe on a locked-down work computer or a borrowed device: there is nothing to download and nothing to log into. Open the page, sign, and you are done.
How to Add a Signature to a PDF Online Free
You can add a signature to a PDF online free in two ways here, and switch between them at any time:
- Draw — sign with your finger on a phone or tablet, or with a trackpad or mouse on a computer. This gives you your real handwritten signature.
- Type — type your name and it is rendered in a handwriting-style cursive font. Handy when you are at a desktop without a touch screen.
Whether you need to fill and sign a PDF online free or simply add a signature to a finished document, either method produces the same result: the signature is saved as a crisp, transparent image and embedded into the PDF at the exact spot and size you choose. This is an electronic signature — a visible signature added to the document — which is what the vast majority of forms, agreements, and applications ask for.
Nothing Is Uploaded
Most "sign PDF online" sites upload your file to their servers to process it — which means a private contract, with names, addresses, and amounts on it, ends up on someone else's computer. This tool is different: it runs entirely in your browser. The PDF is opened, the signature is embedded, and the signed file is saved locally, so you can sign a PDF online free with nothing uploaded anywhere.
Frequently Asked Questions
Can I sign a PDF online free with no account?
Yes. Signing a PDF here is completely free and there is no account, sign up, or email required. Open the page, choose your PDF, draw or type your signature, place it on the page, and download the signed file. Everything runs in your browser, so there is nothing to register for.
How do I sign a PDF without Adobe?
You do not need Adobe Acrobat or any desktop software. Open this page in any browser, choose your PDF, and add your signature by drawing or typing it. When you tap Save Document, the signature is embedded into the PDF and downloaded — no Adobe, no install, no subscription.
Is my document uploaded when I sign it here?
No. Your PDF is opened and signed entirely on your device — it is never uploaded to a server. The signature is embedded locally in your browser and the signed file is saved straight to your downloads, so a private contract or form never leaves your computer or phone.
How to sign a PDF without printing?
There is no need to print and scan. Open the PDF, draw your signature with a finger or mouse (or type your name in a cursive font), and drag it onto the signature line. The signature is added directly to the digital file, so you skip the print-sign-scan cycle entirely.
Can I sign a PDF on iPhone for free?
Yes. Open this tool in Safari or Chrome on your iPhone and pick the PDF from Files or iCloud. Draw your signature with your finger, position it on the page, and download the signed PDF. It works the same way on iPad and Android phones — no app to install.
Can I sign a PDF on Mac for free?
Open this page in Safari or Chrome on your Mac and choose the PDF from Finder. Draw your signature on the pad with the trackpad or mouse, or type it, then drop it where you need it and download. It is a quick, free alternative to Preview or Acrobat for adding a signature.
What does "electronically sign a PDF" mean?
Electronically signing a PDF means adding your visible signature — drawn or typed — into the document instead of signing it on paper. This tool embeds that signature image into the file. It is an electronic signature for everyday forms and agreements, not a certificate-based cryptographic digital signature.
