PDF annotations in PDF Viewer components allow users to interact with and mark up documents directly within an application. This functionality is critical for workflows requiring collaborative review, document editing, or enhanced personalization of PDFs, offering a seamless experience for annotating without requiring external tools. By embedding annotation capabilities, applications can boost productivity and streamline document-centric tasks.

Common features include:

• Freehand Draw (Ink Annotation) allow users to draw freeform shapes, lines, or highlights directly onto a PDF using a stylus, mouse, or touch input.
• Lines allow users to underline text, create dividers, or connect different areas of the document for clear and professional markup.
• Rectangles are ideal for framing sections of a document. Users can highlight specific text or data, making it stand out without permanently altering the original content.
• Ellipses enable users to easily call attention to charts, images, or other graphical elements.
• Stamp annotations let users apply predefined or custom stamps, such as "Approved," "Rejected," or company logos. This provides a fast and visually impactful way to signify document status or ownership.
• Free Text annotations allow users to add independent text boxes anywhere on the document. This tool is helpful for inserting notes, instructions, or additional details without modifying the underlying content.
• Watermarking PDFs embeds text or images, such as "Confidential" or a company name, across a PDF. It ensures documents are properly branded or marked for security purposes without obstructing readability.

Printing to PDF allows users to save an existing document, webpage, or file as a PDF by using a virtual printer. It captures the document exactly as it would appear if printed, preserving the formatting, layout, and styling. The resulting document is typically static and cannot be edited, ideal for archiving or sharing finalized versions of a document. This feature is particularly useful for standardizing outputs across different software, ensuring consistent presentation, and providing an easy way to generate PDFs from files that do not natively support the format. By integrating PDF viewers with this functionality, developers can streamline the creation of high-quality, portable documents directly from a wide range of applications.

Several JavaScript PDF viewers allow users to print to PDF, including:
