- Use browser friendly code fontkit#208 fontkit#209 linebreak#18
PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. The API embraces chainability, and includes both low level functions as well as abstractions for higher level functionality. The PDFKit API is designed to be simple, so generating complex documents is often as simple as a few function calls.
Check out some of the documentation and examples to see for yourself! You can also read the guide as a self-generated PDF with example output displayed inline. If you'd like to see how it was generated, check out the README in the docs folder.
You can also try out an interactive in-browser demo of PDFKit here.
Installation uses the npm package manager. Just type the following command after installing npm.
npm install pdfkit
- Vector graphics
- HTML5 canvas-like API
- Path operations
- SVG path parser for easy path creation
- Linear and radial gradients
- Line wrapping
- Text alignments
- Bulleted lists
- Font embedding
- Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collections (.ttc), and Datafork TrueType (.dfont) fonts
- Font subsetting
- See fontkit for more details on advanced glyph layout support.
- Image embedding
- Supports JPEG and PNG files (including indexed PNGs, and PNGs with transparency)
- PDF security
- Access privileges (printing, copying, modifying, annotating, form filling, content accessibility, document assembly)
- Patterns fills
- Higher level APIs for creating tables and laying out content
- More performance optimizations
- Even more awesomeness, perhaps written by you! Please fork this repository and send me pull requests.

The PDF output from this example (with a few additions) shows the power of PDFKit — producing
complex documents with a very small amount of code. For more, see the
demo folder and the
PDFKit programming guide.
There are three ways to use PDFKit in the browser:
- Use Browserify. See demo source code and build script
- Use webpack. See complete example.
- Use prebuilt version. Distributed as
pdfkit.standalone.jsfile in the releases or in the package
In addition to PDFKit, you'll need somewhere to stream the output to. HTML5 has a Blob object which can be used to store binary data, and get URLs to this data in order to display PDF output inside an iframe, or upload to a server, etc. In order to get a Blob from the output of PDFKit, you can use the blob-stream module.
// require dependenciesconst PDFDocument = ;const blobStream = ;// create a document the same way as aboveconst doc = ;// pipe the document to a blobconst stream = doc;// add your content to the document here, as usual// get a blob when you're donedoc;stream;
You can see an interactive in-browser demo of PDFKit here.
Note that in order to Browserify a project using PDFKit, you need to install the
brfs module with npm,
which is used to load built-in font data into the package. It is listed as a
package.json, so it isn't installed by default for Node users.
If you forget to install it, Browserify will print an error message.
