Why eSigning PDFs Is Safer Than Printing

If you’re still printing, signing, and scanning documents in 2025 — you’re not just wasting time, you’re putting your data at risk. While this method may feel familiar, it lacks the legal strength and protection of a proper digital signature.

‍

In this article, we’ll explain why using a digital signature to sign PDF documents online is far more secure than the outdated print-and-scan method. You’ll also learn how tools like DocuChain let you create a digital signature online and protect every document with blockchain-level encryption.

The Risks of Printing and Scanning PDF Documents

‍

Many professionals still sign PDFs manually by printing them, writing a signature, and scanning the document back into a computer. Here’s why that’s a problem:

‍

• There’s no way to verify who signed the file or when

• Scanned files can be easily edited or forged

• No encryption, no audit trail, and no legal protection

• Waste of paper and time

• Inconsistent results and lower quality in scanned PDFs

‍

If you’re handling contracts, agreements, NDAs, or any document that matters — this method simply isn’t secure enough.

‍

‍

What Is a Digital Signature?

‍

A digital signature (or electronic signature) is a legally recognized method to sign documents online with full identity verification and file protection.

‍

When you digitally sign a PDF, you add an encrypted, tamper-proof seal that proves:

‍

• Who signed the document

• When it was signed

• That the file has not been altered since signing

• That the document is legally valid and compliant

‍

Unlike just pasting your name or image into a file, a true digital signature is backed by cryptography and recognized under global laws like ESIGN and eIDAS.

‍

‍

Why Digital Signatures Are More Secure

‍

Here’s why using a digital signature to sign a PDF online is safer than manual signing:

‍

• Encryption: Your document is locked and tamper-proof

• Identity verification: The signer is authenticated before signing

• Legal compliance: Recognized in courts and across jurisdictions

• Timestamping: Every signature is tracked and documented

• Speed: Sign, send, and store instantly without printing or scanning

‍

If you want to secure a PDF file before sending it, adding a verified eSignature online is the safest way.

What About Email Signatures?

‍

Some users think adding their email signature to an attached document is enough. It’s not.

‍

An email signature is useful for communication — name, title, contact info — but it’s not a digital signature. It doesn’t lock the file or verify the signer. It can’t replace a proper e-signature solution.

‍

If you’re attaching a document in your email, make sure it’s already signed with a real electronic signature.

Don’t print and scan — it’s outdated and unsafe.

Don’t rely on visual signatures — they’re not protected.
