jsPDF is a JavaScript library that lets you generate PDF files directly inside a web browser or a Node.js server application, without sending anything to a backend server. The problem it solves is that PDF generation traditionally required server-side software, meaning a user's browser would have to make a request, a server would generate the PDF and send it back. jsPDF eliminates that round trip by creating the PDF entirely on the client side (in the user's own browser), which is faster and works offline. You use it by creating a new document object and then calling methods to add content: text, images, shapes, HTML content, and more. When done, you call a save method and the browser downloads the finished PDF file. You can control paper size, orientation (portrait or landscape), and measurement units. Custom fonts (including Unicode and non-Latin scripts) can be added by converting TTF font files using a bundled tool. For example, generating a simple one-page PDF with the words "Hello world" and saving it as a file requires just three lines of code: create the document, add a text element at coordinates, then save. The library works in the browser via standard script or module imports, and in Node.js for server-side or scripted PDF generation. It integrates well with popular frontend frameworks like React, Angular, and Vue. For rendering HTML content into PDF, it can optionally use the html2canvas library (which renders a webpage section as an image) as a dependency. You would use jsPDF whenever a web application needs to let users export reports, invoices, receipts, or any structured data as a downloadable PDF file. The library is written in plain JavaScript and distributed via npm.
