Why Sign PDFs Without Printing?
Printing, signing, and scanning a PDF is slow, wastes paper, and produces a lower-quality result than a digital signature. With modern browser tools, you can sign a PDF in under a minute without any special software or a printer.
Three Ways to Sign a PDF
There are three main approaches to adding a signature digitally:
- Draw: use your mouse or touchscreen to draw your handwritten signature
- Type: type your name and choose a handwriting-style font
- Upload: upload an image of your physical signature (PNG with transparent background works best)
Is a Digital Signature Legally Binding?
A simple drawn or typed signature (sometimes called an 'electronic signature') is legally valid for most everyday documents under laws like the US ESIGN Act and the EU's eIDAS regulation. However, for high-stakes documents like property transfers, wills, or court filings, some jurisdictions require a qualified digital signature with a certificate from a trusted authority. When in doubt, check with the document recipient.
How to Sign a PDF in Your Browser
1. Open the Fill & Sign tool and drop in your PDF. 2. Select the signature tool from the toolbar. 3. Choose Draw, Type, or Upload. 4. Place the signature on the page — drag to reposition, resize handles to scale. 5. Click Download to save the signed PDF.
- Zoom in before placing the signature for pixel-perfect placement
- For typed signatures, the tool renders using a cursive font automatically
- Transparent PNG signatures look most professional on signed documents
Signing Multi-Page Documents
If you need to sign on multiple pages (e.g., initials on each page plus a full signature at the end), you can add multiple signature elements before downloading. Each signature is rendered as a permanent image overlay on the page.
After Signing: Flatten Before Sharing
Once signed, consider flattening the PDF before sending. Flattening converts the signature overlay into the page permanently, so it can't be moved or deleted by the recipient. Use the Flatten PDF tool after signing.
