A library to generate PDFs in JavaScript.
You cancatch me on twitter:@MrRio or head over tomy company's website for consultancy.
jsPDF is now co-maintained byyWorks - the diagramming experts.
Recommended: get jsPDF from npm:
npm install jspdf --save# oryarn add jspdf
Alternatively, load it from a CDN:
<scriptsrc="https://cdnjs.cloudflare.com/ajax/libs/jspdf/3.0.0/jspdf.umd.min.js"></script>
Or always get latest version viaunpkg
<scriptsrc="https://unpkg.com/jspdf@latest/dist/jspdf.umd.min.js"></script>
Thedist
folder of this package contains different kinds of files:
- jspdf.es.*.js: Modern ES2015 module format.
- jspdf.node.*.js: For running in Node. Uses file operations for loading/saving files instead of browser APIs.
- jspdf.umd.*.js: UMD module format. For AMD or script-tag loading.
- polyfills*.js: Required polyfills for older browsers like Internet Explorer. The es variant simply imports allrequired polyfills from
core-js
, the umd variant is self-contained.
Usually it is not necessary to specify the exact file in the import statement. Build tools or Node automatically figureout the right file, so importing "jspdf" is enough.
Then you're ready to start making your document:
import{jsPDF}from"jspdf";// Default export is a4 paper, portrait, using millimeters for unitsconstdoc=newjsPDF();doc.text("Hello world!",10,10);doc.save("a4.pdf");
If you want to change the paper size, orientation, or units, you can do:
// Landscape export, 2×4 inchesconstdoc=newjsPDF({orientation:"landscape",unit:"in",format:[4,2]});doc.text("Hello world!",1,1);doc.save("two-by-four.pdf");
const{ jsPDF}=require("jspdf");// will automatically load the node versionconstdoc=newjsPDF();doc.text("Hello world!",10,10);doc.save("a4.pdf");// will save the file in the current working directory
AMD
require(["jspdf"],({ jsPDF})=>{constdoc=newjsPDF();doc.text("Hello world!",10,10);doc.save("a4.pdf");});
Globals
const{ jsPDF}=window.jspdf;constdoc=newjsPDF();doc.text("Hello world!",10,10);doc.save("a4.pdf");
Some functions of jsPDF require optional dependencies. E.g. thehtml
method, which depends onhtml2canvas
and,when supplied with a string HTML document,dompurify
. JsPDF loads them dynamically when required(using the respective module format, e.g. dynamic imports). Build tools like Webpack will automatically create separatechunks for each of the optional dependencies. If your application does not use any of the optional dependencies, youcan prevent Webpack from generating the chunks by defining them as external dependencies:
// webpack.config.jsmodule.exports={// ...externals:{// only define the dependencies you are NOT using as externals!canvg:"canvg",html2canvas:"html2canvas",dompurify:"dompurify"}};
InVue CLI projects, externals can be defined via theconfigureWebpackorchainWebpack properties of thevue.config.js
file(needs to be created, first, in fresh projects).
InAngular projects, externals can be defined usingcustom webpack builders.
InReact (create-react-app
) projects, externals can be defined by either usingreact-app-rewired or ejecting.
jsPDF can be imported just like any other 3rd party library. This works with all major toolkits and frameworks. jsPDFalso offers a typings file for TypeScript projects.
import{jsPDF}from"jspdf";
You can add jsPDF to your meteor-project as follows:
meteor add jspdf:core
jsPDF requires modern browser APIs in order to function. To use jsPDF in older browsers like Internet Explorer,polyfills are required. You can load all required polyfills as follows:
import"jspdf/dist/polyfills.es.js";
Alternatively, you can load the prebundled polyfill file. This is not recommended, since you might end uploading polyfills multiple times. Might still be nifty for small applications or quick POCs.
<scriptsrc="https://cdnjs.cloudflare.com/ajax/libs/jspdf/3.0.0/polyfills.umd.js"></script>
The 14 standard fonts in PDF are limited to the ASCII-codepage. If you want to use UTF-8 you have to integrate acustom font, which provides the needed glyphs. jsPDF supports .ttf-files. So if you want to have for exampleChinese text in your pdf, your font has to have the necessary Chinese glyphs. So, check if your font supportsthe wanted glyphs or else it will show garbled characters instead of the right text.
To add the font to jsPDF use our fontconverter in/fontconverter/fontconverter.html.The fontconverter will create a js-file with the content of the provided ttf-file as base64 encoded stringand additional code for jsPDF. You just have to add this generated js-File to your project.You are then ready to go to use setFont-method in your code and write your UTF-8 encoded text.
Alternatively you can just load the content of the *.ttf file as a binary string usingfetch
orXMLHttpRequest
andadd the font to the PDF file:
constdoc=newjsPDF();constmyFont= ...// load the *.ttf font file as binary string// add the font to jsPDFdoc.addFileToVFS("MyFont.ttf",myFont);doc.addFont("MyFont.ttf","MyFont","normal");doc.setFont("MyFont");
Since the merge with theyWorks fork there are a lot of new features. However, someof them are API breaking, which is why there is an API-switch between two API modes:
- In "compat" API mode, jsPDF has the same API as MrRio's original version, which means full compatibility with plugins.However, some advanced features like transformation matrices and patterns won't work. This is the default mode.
- In "advanced" API mode, jsPDF has the API you're used from the yWorks-fork version. This means the availability ofall advanced features like patterns, FormObjects, and transformation matrices.
You can switch between the two modes by calling
doc.advancedAPI(doc=>{// your code});// ordoc.compatAPI(doc=>{// your code});
JsPDF will automatically switch back to the original API mode after the callback has run.

Feature requests, bug reports, etc. are very welcome as issues. Note that bug reports should follow these guidelines:
- A bug should be reported as anmcve
- Make sure code is properly indented andformatted (Use ``` around code blocks)
- Provide a runnable example.
- Try to make sure and show in your issue that the issue is actually related to jspdf and not your framework of choice.
jsPDF cannot live without help from the community! If you think a feature is missing or you found a bug, please considerif you can spare one or two hours and prepare a pull request. If you're simply interested in this project and want tohelp, have a look at the open issues, especially those labeled with "bug".
