jsPDF
Client-side JavaScript library for generating PDF documents directly in the browser or Node.js.
What is jsPDF?
jsPDF is a client-side JavaScript library that allows developers to generate PDF documents directly in web browsers or Node.js environments. It solves the problem of creating downloadable PDFs without server-side dependencies, enabling dynamic report generation, invoice creation, and document exports in web applications. The library provides a simple API for adding text, images, and custom fonts to PDF files with control over layout and formatting.
Frontend and full-stack JavaScript developers building web applications that require dynamic PDF generation, such as dashboards, e-commerce platforms, or reporting tools. It's also suitable for Node.js developers needing server-side PDF creation capabilities.
Developers choose jsPDF because it eliminates server-side PDF processing overhead, works entirely in the browser for faster client-side generation, and offers a straightforward API with extensive customization options. Its dual API modes provide both simplicity for basic use cases and advanced features for complex PDF manipulation.
Overview
Client-side JavaScript PDF generation for everyone.
Use Cases
Best For
- Generating invoices or receipts directly in web applications
- Creating downloadable reports from dashboard data
- Exporting user-generated content as PDF documents
- Building client-side document generation tools
- Adding PDF export functionality to React, Vue, or Angular apps
- Server-side PDF generation in Node.js applications
Not Ideal For
- Projects requiring pixel-perfect HTML-to-PDF conversion, as jsPDF relies on html2canvas which can misrender complex CSS or dynamic content.
- High-volume server-side PDF generation where performance is critical, as dedicated server libraries like PDFKit may offer better optimization.
- Applications needing built-in accessibility features or interactive PDF forms, as jsPDF focuses on basic generation with limited advanced PDF standards support.
- Teams wanting a visual or drag-and-drop PDF design tool, since jsPDF requires manual code-based layout and styling.
Pros & Cons
Pros
Creates PDFs entirely in the browser, reducing server load and latency for dynamic web apps like dashboards or invoicing tools.
Integrates TrueType fonts via a font converter or binary loading, enabling UTF-8 and multilingual text rendering beyond basic ASCII.
Supports various paper sizes, orientations (portrait/landscape), and units (mm, inches), allowing precise layout control.
Works in browsers and Node.js with modular builds (ES, UMD, Node), ensuring broad environment support without server dependencies.
Cons
Compat and advanced API modes can confuse developers, with features like transformation matrices only available in advanced mode, leading to integration hurdles.
Features like HTML to PDF require external libraries (html2canvas, dompurify), adding setup complexity and potential bundle bloat in webpack builds.
In Node.js, file system access needs careful permission flags or allow lists, and user input must be sanitized to prevent vulnerabilities, increasing setup time.
