How to Annotate a PDF in Chrome: 3 Easy Ways

Can I Annotate a PDF in Chrome?

People often ask if it is possible to annotate a PDF in Chrome without paying for extra tools. Yes, Google Chrome offers built-in tools that allow you to do exactly this. You can use a digital pen to draw arrows or a highlighter tool to mark important words in bright colors.

However, Chrome is still very limited. It is meant for quick, simple tasks. You cannot easily add custom stamps, draw perfect shapes, or edit the original text on the page. If you want a full set of professional annotation tools to properly annotate a PDF, you should try JOPDF.

JOPDF is a desktop program that gives you total control over your files. The best part is that JOPDF is 100% FREE with absolutely no hidden costs or subscriptions.

How to Annotate a PDF in Chrome

If you want to annotate a PDF opened in Chrome, there are three simple methods you can choose from. You can use the built-in tool or online tools for more features.

Way 1. Use the Built-in Annotation Tools

Chrome has native drawing tools right on the screen. Here is how to annotate a PDF in Google Chrome using these new, built-in features:

• First, find the document on your computer. Drag and drop your file into a new, blank Chrome tab to open a PDF in Chrome.
• Look at the top of the screen. You will see a small Draw icon. Click this icon to open the new drawing menu.
• A panel will appear with different choices. Select the Highlighter tool if you want to color over text. Select the Pen tool if you want to draw on a PDF in Chrome using your mouse. You can even change the thickness of the lines and choose different colors like red, blue, or green.

• If you make a mistake, simply click the Eraser tool. Click once on your drawing, and it will disappear completely.
• This is the most important step! Click the download button in the top right corner. The browser will ask if you want to save the file “With your changes” or “Without your changes.” Choose to save your changes so your new drawings are permanently baked into the file.

Way 2. Use an Extension

An extension is a tiny program you can add to your web browser to give it extra features. If the built-in Chrome tools are not enough for you, an extension can add more options.

• Open the Chrome Web Store in your browser.
• Type “PDF annotator” into the search bar. You will see tools like Adobe Acrobat or Web Highlights. Click the button that says “Add to Chrome” to install it.

• Click the new puzzle piece icon at the top of your screen, and then upload your document. Now you can select the annotate tool, adjust the settings, and put it on your document.

Way 3. Use an Online Annotator (Smallpdf)

If you do not want to install any extensions, you can use a web-based service directly inside your Chrome window.

• Open Chrome and visit a trusted online tool website like Smallpdf.
• Click the button on the screen to upload the file from your computer to the webpage.

• Once your file loads on the screen, use the website’s toolbar. You can easily highlight text, add text boxes, or draw shapes on the page.

• When your document is perfectly marked up, click the blue Download button. The website will quickly process your changes, and you can download the newly annotated document to your computer.
