FAQ
PDF signature guide: frequently asked questions
What is the fastest way to sign a PDF online?
Open the PDF in the signing tool, draw or select your signature, place it on the page and download. With a signature already saved in the browser it takes only a few seconds, and there is no account to create first.
Do I need an account to sign a PDF?
No. There is no sign-up, no email address and no confirmation step. The signature is created in the browser and saved there if you want to reuse it, so nothing depends on an account existing.
Can I sign a PDF on Windows or Mac without installing software?
Yes. Everything runs in the browser, so there is nothing to install on either platform, and the same is true on a phone or tablet. That also makes it usable on a locked-down work computer where you cannot install applications.
What if the PDF is a scan rather than a digital document?
It still works. A scanned PDF is a set of page images, so the signature is drawn over the page in the same way. The signed result is delivered as a PDF with your signature visibly applied to the scanned page.
How do I add a date next to my signature?
Type the date as well as placing the signature, positioning it on the date line. Where a form asks for a printed name and a date alongside the signature, all three can be placed on the page before you download.
Can I sign a PDF without uploading it to a website?
Yes, and with this tool that is the only way it works. The PDF is read and rewritten in your browser, so a confidential contract or a document containing personal details never leaves your device.
Complete Guide to Signing PDF Documents Online
Signing PDF documents no longer requires expensive software, a printer, or a scanner. With modern browser-based tools, you can add a professional electronic signature to any PDF file directly from your computer, phone, or tablet. This guide covers everything you need to know about online PDF signing — from choosing the right method to ensuring your signature looks professional and meets legal requirements.
Method 1: Draw your signature directly on the PDF
This is the most straightforward approach. Upload your PDF, click "Add signature," and draw with your mouse, trackpad, or touchscreen. The tool uses pen-smoothing algorithms to clean up shaky mouse movements, so even imprecise drawing produces a clean result. Once placed, drag the signature to the correct position, resize it to match the document, and download the signed file. This method works best for one-off signing when you don't have a saved signature file.
Method 2: Upload a pre-made signature image
If you already have a transparent PNG signature (created with our signature generator or extracted from a previous document), upload it as your signature stamp. This approach gives you the most consistent results across documents because you're using the same signature image every time. It's also the fastest method for people who sign multiple documents regularly.
Method 3: Type your name in a handwriting font
Type your full name and choose from 50+ handwriting fonts to instantly generate a signature. This produces the cleanest, most readable result and is ideal for formal documents where legibility matters. Add a slight rotation to make it look less computer-generated.
Understanding e-signature legality
Electronic signatures created with browser-based tools are legally recognized in most countries for everyday documents. The US ESIGN Act, EU eIDAS regulation, and similar laws in Canada, Australia, and the UK all give electronic signatures the same legal weight as handwritten ones for commercial transactions. The main exceptions are documents that specifically require notarization, court filings, or certain government forms — always check with the receiving organization if you're unsure.
