PDF content types
Bring PDFs to life with a wide range of supported content types. The JavaScript PDF library enables developers to add text, images, shapes, and lists, each serving a unique role in document design and functionality. Text elements allow precise placement of headings, paragraphs, and labels with customizable styles. Images embed logos, product visuals, or diagrams anywhere on the page. Shapes and vector graphics are used to add charts, diagrams, and design elements. By combining these content types, developers can create dynamic, professional PDFs tailored for business reports, contracts, architectural plans, maps, and design mockups.
Build Layered and Structured PDFs
Design professional and interactive documents by choosing exactly where content should appear in PDFs. The JavaScript PDF library provides APIs to add elements directly to pages, apply reusable templates for watermarks, and organize complex layouts using layers whose visibility can be controlled programmatically or by users in supported PDF viewers. This placement flexibility makes it easy to build consistent, multi layered documents such as reports, contracts, architectural plans, maps, and dynamic presentations.

Organize large documents effectively by splitting PDFs into smaller, more manageable sections. The split functionality enables files to be divided by fixed page counts or custom page ranges, giving complete control over how the content is structured. Each output file is generated instantly, making it simple to store, share, or edit further. Split PDFs are ideal for scenarios such as distributing lengthy reports, extracting chapters from study materials, isolating legal clauses, or categorizing invoices and receipts. With flexible options and precise validation, document management is streamlined, ensuring accuracy and efficiency.
