Roadmap for Syncfusion^® PDF Viewer SDK

Web PDF Viewer (JavaScript, Angular, React, Vue, ASP.NET Core, and ASP.NET MVC)

Digital signature

Enables digital signing of PDF documents and validation of existing signatures directly within the PDF Viewer. It helps ensure document authenticity, integrity, and non-repudiation while supporting secure digital approval and compliance workflows.

PDF layer

Enables viewing and managing PDF layers directly in the PDF Viewer. Users can show or hide individual layers to focus on specific content, making it especially useful for technical drawings, engineering documents, architectural plans, and multi-layered PDFs.

Interactive barcode form fields

Introduces interactive barcode form fields in PDF documents. Users can view and interact with barcode fields directly in the PDF Viewer.

PDF actions (form fields)

This feature supports PDF actions associated with form fields, allowing organizations to create more dynamic PDF forms directly in the viewer.

Date and time picker form field

The date and time picker form fields in PDF documents allow easy selection of dates and times through an intuitive interface, reducing manual entry errors and enhancing the form-filling experience.

Button form field

Interactive button form fields allow users to trigger workflows directly within PDF documents. This enhances PDF form interactivity and user engagement.

Appearance-based annotation rendering

Enables the PDF Viewer to render annotations using their embedded appearance streams, ensuring a consistent visual representation across PDF viewers. It improves fidelity when displaying imported documents by preserving annotation styles, colors, borders, opacity, and custom visual effects exactly as authored in the source PDF.

Bookmark editing and creation

Allows creating, editing, organizing, and managing PDF bookmarks directly within the viewer. It improves document navigation, especially for lengthy documents, by enabling quick access to important sections and frequently referenced content.

Move annotations between pages

Allows moving annotations between document pages while preserving their properties and formatting. This improves editing flexibility and enables efficient document modifications without recreating annotations.

Single-page, two-page, and page rotation modes

Provides multiple document viewing modes, including single-page view, two-page spread view, and page rotation. Users can customize their reading experience based on document type and preferences, improving accessibility and productivity.

Free text callout annotation

Allows users to associate comments with specific areas of a document through leader lines and callout pointers. It enhances document review workflows by providing clear contextual feedback and visual references for annotations.

Cloud border style for annotations

Enables the creation of visually distinct markups with cloud-shaped borders. It improves document review experiences by making highlighted areas more noticeable and consistent with standard PDF annotation practices.

Attachment annotation

Enables embedding and direct access to supplemental files within a PDF document. It improves collaboration by allowing related documents, images, and supporting resources to be attached to specific locations in the PDF.

Freehand highlight annotation

Allows highlighting document content using freehand drawing gestures. It provides a natural annotation experience for touch and stylus-enabled devices while supporting intuitive document review and markup workflows.

Polyline annotation

Allows the drawing of connected line segments across PDF pages, which is useful for technical reviews, design markups, and workflows that require highlighting relationships among multiple points.

Arc annotation

Enables users to create curved markup shapes in PDF documents. It is particularly useful for technical drawings, engineering reviews, and design validation workflows that require curved measurements and visual references.

Blazor PDF Viewer

Active viewport rendering

Optimizes rendering performance by prioritizing pages visible in the current viewport. Instead of rendering all pages simultaneously, the viewer dynamically renders content based on user navigation and scrolling, resulting in faster load times and improved responsiveness for large PDF documents.

Custom appearance annotation rendering

Enables rendering of annotations using custom appearance streams embedded in PDF documents. It ensures accurate visualization of imported annotations by preserving custom styles and visual properties as intended by the document author.

.NET MAUI PDF Viewer

PDF page organization (rotate, delete, and rearrange pages)

This feature provides comprehensive page management capabilities within the PDF Viewer. Users can rotate pages, remove unwanted pages, and rearrange page order directly from the application, simplifying document organization and editing workflows.

Embedded annotation appearance stream rendering

Accurately renders annotations based on their embedded appearance streams. It ensures consistent annotation display across platforms and PDF viewers by preserving the original visual representation defined in the PDF document.

Copy and paste annotation

Enables quick duplication of annotations across pages or documents using familiar copy-and-paste operations. It improves productivity by reducing repetitive annotation creation while preserving annotation formatting and properties.

Free text callout annotations

Enables the creation and editing of free-text callout annotations with leader lines and pointer arrows. It enhances mobile and cross-platform review workflows by providing clear visual connections between comments and document content.
