jsPDF
Client-side PDF generation library for browsers and Node.js. jsPDF generates PDF documents programmatically using a drawing API — addText(), addImage(), addPage(), drawLine(). Supports custom fonts, images, tables (via autotable plugin), and basic vector graphics. Primarily a client-side tool — generates PDFs entirely in the browser without server involvement.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Client-side generation — no server-side risk. PDF content reflects input data — XSS not applicable to PDF context. Trusted input recommended.
⚡ Reliability
Best When
You need client-side PDF generation from data (tables, charts, text) without server infrastructure and don't need HTML-to-PDF conversion.
Avoid When
You need to render HTML/CSS as PDF — use Puppeteer or WeasyPrint. jsPDF is an imperative drawing API, not an HTML renderer.
Use Cases
- • Generate downloadable PDF reports in browser-based agent tools without server-side PDF infrastructure
- • Create invoices, receipts, and certificates as PDFs client-side from JavaScript/TypeScript data
- • Export data tables to PDF using jsPDF-AutoTable plugin for tabular data with pagination
- • Build print-ready document generation workflows that run entirely in the browser
- • Generate PDFs in React applications without needing a PDF rendering server
Not For
- • HTML-to-PDF conversion — jsPDF doesn't render HTML; use Puppeteer, wkhtmltopdf, or WeasyPrint for HTML rendering
- • Complex document layouts with CSS — jsPDF is imperative drawing API; html2canvas can partially bridge this gap
- • PDF parsing or manipulation of existing PDFs — use pdf-lib or PyMuPDF for existing PDF editing
Interface
Authentication
No authentication — local PDF generation library.
Pricing
MIT-licensed open source library.
Agent Metadata
Known Gotchas
- ⚠ jsPDF draws content at absolute coordinates — agent code must manually calculate x/y positions for all content; no layout engine or CSS-like positioning
- ⚠ Custom font support requires converting fonts to Base64 and including in the bundle — system fonts are not available; only built-in fonts (Helvetica, Courier, Times) work without extra setup
- ⚠ Images must be loaded and converted to Base64/ArrayBuffer before passing to addImage() — async image loading requires explicit await before PDF generation
- ⚠ jsPDF-AutoTable is a separate plugin with its own API and version compatibility — ensure plugin version matches jsPDF version
- ⚠ Large PDFs with many images can exhaust browser memory — consider server-side generation (Puppeteer) for complex documents
- ⚠ Unicode and non-Latin character support requires adding custom Unicode fonts — default fonts only support Latin character sets
