What Is a Wet Signature?

A wet signature is a signature signed on paper with wet ink, thus the name. In other, simpler words, it is a handwritten signature. That type of signature was the only way to sign documents when digital tools were not so commonplace.

When Will You Need a Wet Signature?

Suppose someone sent you a printed document that you need to sign. You will not scan that document to sign it with a digital signature. Instead, you will grab a pen and sign the document on paper. Some companies also require documents to be signed physically, even if the documents are in PDF form. These are the scenarios when you'd need a wet signature.

How To Do a Wet Signature on PDF?

Some companies and individuals are more lenient. They allow you to sign documents using digital tools, so long as the signature is handwritten. That removes the hassle of printing the document, signing it with a pen, and scanning it to convert it to digital form. Professionals who want to maximize their time to increase productivity appreciate that a lot.

Pros and Cons of Wet Signatures

What are the advantages and disadvantages of using wet signatures? Find out below.


Wet signatures are better for branding. It feels more personal since the impression is made with the signer's handwriting. Think of autographs. A book with the wet signature of the author would feel more special than the same book but with a digital signature.


Using wet signatures can be costly. You need to buy a pen and ink to sign the documents and paper to print them. Furthermore, you need to print and scan the document to send it online. Therefore, it is a time- and resource-consuming process.

Forgery is also a problem with wet signatures. With enough practice, one can replicate even a complex signature.

Signing with wet signatures means you are using paper. And trees are cut down to produce paper. So, using wet signatures is bad for the environment.

Comparison Between Wet Signatures, Electronic Signatures, and Digital Signatures

Wet signatures, as stated above, are impressions you make on paper with wet ink. On the other hand, electronic signatures are signatures you add to digital documents using tools like Wondershare PDFelement.

Digital signatures are the more advanced version of electronic signatures. They come with a certificate containing encrypted information unique to you. Other people can use this certificate to verify the authenticity of the signature.

Other people who can access your computer can add your electronic signatures without your consent. They only need to have an image of your signature or know where they can find it.

They can't do that with digital signatures. To add your digital signature to PDF files, they need to use your digital ID. Digital IDs are password protected. So, unless you tell them your password, they can't use it. Using digital signatures is the most secure way to sign documents.


Though there are better alternatives to wet signatures, some organizations and individuals still prefer them. Adding them to PDF documents is how you expect it. You print the document, sign it, scan it, then send it back to the other party. It's quite a tedious task.

Suppose they allowed you to use a scanned copy of your signature or digitally draw it. You can use Wondershare PDFelement. This program lets you insert your handwritten signature into PDF documents very quickly. Also, it comes with a digital signature feature, which you can use for signing other important documents.
