Easily annotate PDFs on Windows 10.

When you need to add edits to a PDF or make comments for changes to a work or personal project, you can easily annotate your files online with Adobe Acrobat.

When you’re collaborating on a project and need to review, highlight, and reply to comments on a PDF file on Windows 10, digital collaboration tools like Adobe Acrobat online services make it easy to learn how to type on a PDF and annotate from anywhere.

Here’s how to annotate PDFs on Windows 10.

1. Navigate to Acrobat online service's free PDF editor in your preferred browser.
2. Click the Select a File button or drag and drop your file into the drop zone.
3. Sign in to make edits to your file using either an Adobe login or one of the other login methods, such as with a Google or Apple account.

From there, you can:

• add sticky notes
• highlight
• strike through
• underline
• add text
• draw freehand directly onto the PDF

Some remote tools allow you to choose different colors, which makes it easy to differentiate your edits from others’. After you annotate your file, you can download it or select the option to share it with others via a link.

Why annotate PDFs on Windows 10?

Windows 10 includes Microsoft Edge as the default browser, and you can use the Microsoft Edge PDF viewer to edit PDFs on Windows for free, directly in the browser. There is no “annotate” button. You can draw or write on the PDF, highlight text in different colors, or make a comment.

1. Open Microsoft Edge and navigate to the PDF in the browser, or find the file on your computer and select Open with > Microsoft Edge.
2. To draw or write freehand, select the pen icon from the toolbar. Click the downward arrow to select the color and size of the pen stroke.
3. To highlight in a color, select the text you would like to highlight, right-click, and select Highlight from the drop-down menu. Then select the color.
4. To comment, select the text you would like to comment on, right-click, and select the comment icon from the drop-down menu.
5. Type your comment in the box that appears.
6. Save the comment by clicking the checkmark in the upper-right corner of the comment box.
7. Save changes by clicking the floppy disk icon.

If you are using a fillable form in Microsoft Edge, select the text boxes that allow you to type directly in the PDF.
