How to Sign a Document Online
The quick solution above is enough for most everyday PDF signing tasks. Still, knowing the difference between electronic and digital signatures can help you choose the right method for formal, legal, or security-sensitive documents.
Electronic signatures are the most common way to sign documents in daily life, and are best for contracts, business agreements, client approvals, and HR forms. You can usually create an electronic signature in three ways:
Note:
Signing a PDF in Chrome with the built-in tool is essentially drawing on the PDF. It adds an annotation mark, not a true electronic signature workflow, so it has no identity verification, audit trail, or tamper protection.
Digital signatures use certificates or encryption-based verification to confirm who signed the document and whether the file was changed after signing.
This is why adding a digital signature is best for documents that need identity verification or tamper protection, such as legal documents, government forms, and sensitive business files.
Now, let’s move on to the detailed steps for adding a legally binding signature to a PDF.
For quick and informal PDF signing, Chrome’s built-in Draw tool is often the easiest place to start. It lets you add a handwritten mark directly to a PDF without installing any additional tools.
Steps: Open the PDF in Chrome > Click the Draw tool > Draw your signature > Save and share the signed PDF.

Add Signature to PDF in Chrome
However, keep in mind that Chrome’s Draw tool is mainly an annotation feature, not a dedicated signing solution. It’s only for informal documents, quick approvals, or simply marking a PDF before sending it.
If you need form filling, signature images, or a more professional signing experience, use a dedicated PDF signing tool like PDFgear Online Signer instead. Try it below for a cleaner signing experience in Chrome.
Unlike Chrome’s built-in Draw tool, which mainly adds a handwritten annotation to a PDF, a free Chrome PDF editor provides a more complete signing experience.
The quick solution above shows the fastest way to sign a PDF with PDFgear Online Signer, while the steps below explain how to create signatures, fill forms, and make edits before downloading your document.

What Else Can You Do with PDFgear Online Signer?
Besides signing PDFs, PDFgear Online Signer also helps you:
A Chrome extension is useful when you already rely on a browser-based tool such as Adobe Acrobat, or when your workplace requires a specific signing extension. It lets you open and sign PDFs from Chrome, but it may require installation, login, or a paid plan depending on the tool.

How to Use the Adobe Acrobat Chrome Extension to Sign PDF
1. Install the Adobe Acrobat extension from the Chrome Web Store.
2. Open the PDF you want to sign in Chrome.
3. Select Fill & Sign from the Acrobat toolbar.
4. Create a signature and place it on the document.
5. Save or download the signed PDF.
Downside:
Adobe Acrobat Extension requires an account login before signing, and it only lets you save one signature. Some users may also encounter issues where Adobe won’t let them sign a PDF, especially when signing features are unavailable or require additional permissions.
For users who want to sign PDFs in Chrome without registration, PDFgear Online Signer is often the simpler alternative.
Sometimes, you’re not the only person who needs to sign the document. If you need to send a PDF to someone else for approval or signature, eSignGear, built by the PDFgear team as an extension of its signing workflow, helps you request, collect, and track digital signatures online without leaving your browser.
This makes eSignGear a natural next step after preparing or signing a PDF with PDFgear.

Request Signatures Online
1. Upload your PDF to eSignGear and log in to an account.
2. Add your own signature by drawing, typing, or uploading a signature image.
3. Click Add Signee, enter the recipient’s email address, and optionally configure signing order, reminder emails, expiration dates, or a custom message.
4. Place signature fields to show where each person needs to sign.
5. Click Finish and Send to invite others by email.
6. Track the signing progress and download the completed PDF. You can cancel the request at any time if you no longer need the signature.
Now that you’ve seen the main ways to sign a PDF in Chrome, the best choice depends on what you need to do before and after signing.
