Technical Description: Convert a QuillJS delta object into a .pdf BLOB.

How to Install

Install using npm:

npm i quill-to-pdf --save

How Do I Use It?

Pass a QuillJS delta object to the generatePdf() function of the pdfExporter object, which is imported from the quill-to-pdf package. Be sure to await the generatePdf() function, because it returns a Promise.

const quillDelta = quillInstance.getContents();
const pdfBlob = await pdfExporter.generatePdf(quillDelta);

The quillInstance refers to the object created by new Quill(). The pdfExporter refers to the default export of the quill-to-pdf package, which can be imported as follows:

import { pdfExporter } from 'quill-to-pdf';

What Does the Package Do?

This package creates a PDF from a QuillJS delta. In short, this package will allow you to download the contents of your QuillJS in-browser editor as a PDF document.

How Does It Work?

QuillJS stores its editor content in a "delta" format. QuillToPdf parses the Quill delta object using the quilljs-parser package and then generates a PDF from the parsed Quill delta using the PDFKit package.

How Can I Download the PDF Document from the Browser?

You can download the PDF document created by QuillToPDF by using the FileSaver package.

You'll need to install file-saver from npm first.

npm i file-saver --save

You can also install the types, if you're using TypeScript.

npm i @types/file-saver --save-dev

Here is a brief example of how to download the PDF document from the browser.

import { saveAs } from 'file-saver';
import { pdfExporter } from 'quill-to-pdf';
import * as quill from 'quilljs';

// Here is your Quill editor instance
const quillInstance = new Quill();

// Here is your export function
// Typically this would be triggered by a click on an export button
async function export() {
    const delta = quillInstance.getContents(); // gets the Quill delta
    const pdfAsBlob = await pdfExporter.generatePdf(delta); // converts to PDF
    saveAs(pdfAsBlob, 'pdf-export.pdf'); // downloads from the browser

Which QuillJS Formatting Features Are Supported?

Quill offers a wide range of formatting features. QuillToPDF does not currently support all Quill formatting features. This is because replicating some of the QuillJS formats using PDFKit, which this package relies on, is complicated.

The following features are fully supported:

  • Bold
  • Italic
  • Font
  • Link
  • Size
  • Strikethrough
  • Underline
  • Header 1
  • Header 2
  • List
    • Bullet
    • Ordered
  • Block Quote
  • Code Block

The following features are only partially supported:

  • Formula (the raw text of the formula will be inserted into the PDF, not the KaTex formatted version)
  • Image (the image will be inserted with absolute width and height settings)
  • Video (the link to the video will be included in the PDF document)

The following features are NOT supported:

  • Text direction (cannot be switched to right-to-left)
  • Background (cannot color the background of the text)
  • Superscript
  • Subscript
  • Color
  • Inline code
  • Indent (but indents for lists ARE supported)

How Can I Configure QuillToPDF?

Currently, QuillToPDF allows you to configure the styles used for the main text formats that appear in a Quill editor.

Six text formats are currently recognized by QuillToPDF:

  1. Normal—refers to basic text (normal)
  2. Header 1—refers to a level one heading (header_1)
  3. Header 2—refers to a level two heading (header_2)
  4. Block Quote—refers to a block quote (block_quote)
  5. Code Block—refers to a block of code (code_block)
  6. List Paragraph—refers to the text in a bulleted or ordered list (list_paragraph)

QuillToPDF provides default styles for each of these six text formats. For instance, normal text is automatically formatted as Times-Roman font and 12 points in size, whereas header_1 text is automatically formatted as Helvetica-Bold font and 16 points in size.

The default styles for the 6 text formats can be overridden by providing a style configuration object as the second argument to the generatePdf() function.

The configuration object should satisfy the following interface:

interface Config {
    styles: {
        normal?: {
            font?: string;
            fontSize?: number; // specified in points
            baseIndent?: number; // specified in points w/ 72 ppi
            levelIndent?: number; // only used for lists
            indent?: {
                left?: number;
                right?: number;

The object in the styles property above can contain a key for any of the six text formats: normal, header_1, header_2, block_quote, code_block, or list_paragraph.

For example, if I want to override the default style for a level one heading, I could do the following:

// create a configuration object that satisfies the interface above
const config: Config = {
    styles: {
        header_1: {
            font: 'Times-Bold', // default is 'Helvetica-Bold'
            fontSize: 18 // default is 16

// pass the configuration object as the second argument to generatePdf()
const pdfBlob = await pdfExporter.generatePdf(quillDelta, config);

The options for font are limited to those that come pre-packaged with PDFKit:

  • 'Courier'
  • 'Courier-Bold'
  • 'Courier-Oblique'
  • 'Courier-BoldOblique'
  • 'Helvetica'
  • 'Helvetica-Bold'
  • 'Helvetica-Oblique'
  • 'Helvetica-BoldOblique'
  • 'Times-Roman'
  • 'Times-Bold'
  • 'Times-Italic'
  • 'Times-BoldItalic'
