How to Sign a PDF Electronically

Signing a PDF should not require a printer, a scanner, and a blue pen. This guide walks through adding an electronic signature — drawn, typed, or from an uploaded image — exactly where it belongs on the document, plus signing multi-page PDFs and sealing the finished file.

What an electronic signature is

Signing a PDF electronically places a representation of your signature — your drawn name, a typed name, or an uploaded signature image — onto the page, along with an optional date. The result is a completed document you can distribute instantly, with no printing, signing, and scanning loop. Electronic signatures are ordinary workflow tools; the confidence they carry comes from context, not from cryptographic certificates.

Know the difference: an electronic signature (placing your name on a document) is not the same as a qualified digital signature, which uses a certificate to cryptographically prove identity and integrity. If a contract explicitly requires a certified signature, use a service that issues certificates. PDFZento adds the visual signature; it does not issue certificates.

Draw, type, or upload

Draw — the most natural option. Sign with a mouse, trackpad, or finger on a touch screen. Great when you want your real handwriting shape.
Type — pick a font and type your name. Clean and quick for internal approvals and less personal documents.
Upload — bring an existing signature image (PNG, JPG, or WebP). Perfect if you have a scanned or digitally created signature you reuse everywhere.

How to sign a PDF step by step

Open the sign tool. Go to Sign PDF.
Upload the PDF. Drag and drop the agreement or choose it from your device. Everything stays local.
Create your signature. Choose draw, type, or upload, and save it as your signature for this document.
Place it on the page. Drag the signature field onto the signature line — and add a date field alongside if the document calls for one.
Sign the remaining pages. For multi-page contracts, place the signature and date on every page that needs them.
Download. Save the signed PDF. Your original file remains unmodified, so you can sign again with a different placement anytime.

Multi-page contracts

Most agreements need more than one signature. The tool lets you place the signature and date repeatedly across pages — sign the cover, initial each page, and sign the final page in a single pass. When you are done, spot check the last page and any page that references "signature below" to be sure nothing is missing.

After signing: protect and distribute

Once everyone has signed, the document is the final version. Take two small precautions:

Run Protect PDF to lock the signed file with a password so no one edits or replaces it by accident.
Use Redact PDF to permanently black out any personal or confidential data on earlier pages before the signed file goes out.

Privacy: your signature is drawn, typed, or uploaded in your browser, so your handwriting or signature image never leaves your device.

Frequently Asked Questions

What is the difference between a typed signature and a drawn signature?

A typed signature places your name in a selected font as signature text; a drawn signature is your handwritten signature colored in with a mouse, finger, or stylus. Both are legitimate electronic signatures. PDFZento also lets you upload an image of your existing signature — for example a photo of your ink signature or a previous PNG/JPG signature file.

Is signing in PDFZento legally valid?

An electronic signature added with a tool is a way of expressing intent to sign a document. Whether it satisfies a specific legal requirement depends on your jurisdiction and the type of document. Treat the result as an electronic signature, not a qualified digital signature with a certificate. For contracts that require certification, use a dedicated qualified signature service.

Can I sign the same PDF more than once?

Yes. The signature tool lets you place as many signature fields as the document needs — name, date, notes, and multiple signature placements — so you can sign, date, and initial documents in one pass.

Why should a signed PDF be protected afterward?

Adding a signature makes the document final; protecting the signed PDF with a password prevents accidental edits and unauthorized changes. It does not prove who created the signature, but sealing the file after signing is a simple precaution.
