Create your signature once — drawn, typed or from a photo — place it exactly where it belongs and download a signed PDF ready to send.

Tips for professional results

Tip Why
Use blue ink for originals Makes it obvious the document was signed, not copied
Sign at a realistic size About 4–6 cm (1.5–2.5 in) wide looks natural
Place it on the signature line Drag so the signature sits slightly above the line
Add your printed name and date Type them in the form first, or use Add Text to Image for scanned forms

Before you send

Check every page that needs initials or a signature. If you received several files, combine them first with Merge PDF. For large scanned documents, reduce the size with Compress PDF so the signed file is easy to email. To mark a copy as confidential, add a watermark.

Frequently asked questions

Is a signature added this way legally valid?
In many countries, including the US (ESIGN Act) and the EU (eIDAS), a simple electronic signature like this is legally recognised for many everyday documents such as forms, quotes and many contracts. Some documents require a qualified or certified digital signature, a witness or a wet signature. If in doubt, check with the party asking for your signature.
Is this the same as a digital signature with a certificate?
No. This tool places an image of your signature on the page — what most people need for forms and agreements. It doesn't add a cryptographic certificate that proves the document hasn't been changed. For that, you need a certificate-based signing service.
Is my document or signature uploaded?
No. The PDF is opened, signed and saved entirely in your browser. Neither your document nor your signature image is sent to a server or stored.
How do I get a clean signature image?
Sign on white paper with a dark pen, photograph or scan it in good light, and crop it closely. A PNG with a transparent background looks best; the tool automatically trims empty space around drawn and typed signatures.
Can I sign several pages?
Yes. Move to each page and click Place signature again. Each placement can be positioned and sized separately.
