How to sign a PDF online
1. Upload your PDF
Drag and drop the document you need to sign. Files up to 1MB are supported on the free plan.
2. Add your signature
Type your name, draw a signature with your mouse or trackpad, or upload an image of your signature. Drag it onto the page and resize it to fit.
3. Download the signed PDF
Save your signed document instantly. No email, no account, and no watermark added to the file.
Sign a PDF without printing or scanning
Someone sends you a contract, a lease, or an onboarding form that needs your signature. Printing it, signing by hand, and scanning it back is slow and needs a printer you may not have.
PainlessPDF lets you sign any PDF directly in your browser. Add your signature once and place it on a contract, an invoice approval, a job application, or initial every page of a legal document.
Free, with no software to install
There is nothing to download and no Adobe Acrobat licence to buy. The signing tool runs in your browser, so it works the same on Windows, Mac, Linux, and Chromebook.
You never need to create an account or enter a credit card to sign a PDF. Free access is here to stay.
How your file is handled
Your document is processed only to carry out the signing you requested. Files are protected with TLS in transit, and the temporary server session is cleared automatically when it is no longer in use.
Frequently asked questions
Is signing a PDF free?
Yes. You can sign PDFs for free with no trial period, no watermark, and no account required.
Do I need to sign up to sign a PDF?
No. Open the editor, add your signature, and download the signed file without creating an account.
Can I type, draw, or upload my signature?
All three. You can type your name in a signature font, draw a signature with your mouse or trackpad, or upload an image of your existing signature.
Is this an electronic signature?
It adds a visible electronic signature to the document. It is not a certificate-based digital signature, so for documents that require a qualified or notarized signature you should check the specific requirements first.
Can I sign a PDF on Mac or Windows?
Yes. The signing tool runs entirely in a modern browser, so it works on Mac, Windows, Linux, and Chromebook without any download.
