Document Solutions for PDF JS
Document Solutions for PDF JS is a JavaScript PDF API library for building document workflows directly into web applications. Developers can create, load, edit, save, view, and convert PDFs, while adding forms, annotations, rich media, fonts, security features, and structured page content.

Create PDF Documents

Generate PDF files from scratch in JavaScript or TypeScript applications. Add text, graphics, layout elements, images, and pages, then save the finished document in browser or server-side environments.

Edit Existing PDFs

Load and modify PDF documents by adding, deleting, copying, or moving pages. The library also supports page size changes, orientation updates, attachments, outlines, bookmarks, and document metadata management.

Render Text and Fonts

Control text layout with formatting, alignment, wrapping, trimming, spacing, and custom fonts. Unicode support helps applications generate PDFs for multiple languages, including right-to-left and vertical text scenarios.

Add Images and Graphics

Insert, resize, rotate, and position images within PDF documents. Developers can also draw custom shapes, lines, and graphics to build visual document layouts programmatically.

Build Interactive PDF Forms

Create AcroForms with fields such as text boxes, checkboxes, and radio buttons. Applications can import and extract form data, customize field properties, and fill or flatten forms for distribution.

Annotate and Redact Content

Add comments, highlights, notes, and other annotations for review workflows. Redaction features help remove or obscure sensitive content when preparing documents for controlled sharing.

Convert PDF Pages

Convert PDF pages to image formats such as JPEG and PNG, or export pages to Scalable Vector Graphics (SVG). These capabilities support previews, web display, archiving, and downstream document processing.

Extract Text and Metadata

Search, extract, and locate text across PDF pages with matching options. The API can also retrieve document properties such as author, title, and creation details for document management workflows.

View PDFs in Applications

The product includes a JavaScript PDF viewer for displaying documents in web applications. It supports client-side viewing and can work with editing options depending on the selected viewer capabilities.
