• Standard PDF Editing Features (render, watermark, redact, sign, forms, and more)

PDFix SDK is a cross-platform PDF processing tool, that offers various ways of the integration. Developers can use the PDFix SDK with programming languages to take advandatage of the full control over the PDF documents.

Taking Advantages of WebAssembly

Leverage the advantages of the PDFix SDK WebAssembly build for use in both Node.js and web applications. This allows to execute code at near-native speeds. Reduce the need for server-side processing and improve your web app responsiveness.

Getting Started

Using this package, you can get started either in Node.js or in browser - web environment.

To install the package, run this command:

npm i pdfix-sdk

For use in Node.js

const Pdfix = require('pdfix-sdk');

const pdfixSdkWrapper = new Pdfix();
pdfixSdkWrapper.loadPdfixSdk().then(() => {
  const pdfixSdk = pdfixSdkWrapper.getPdfixSdk();
  const pdfix = pdfixSdk.GetPdfix();
  const pdfDoc = pdfixSdkWrapper.openDocumentFromPath("<YOUR_DOCUMENT_PATH>");

  // your code ...

  pdfDoc.Close();
  pdfix.Destroy();
});

For use in Web (browser)

Run this command in the location of installed NPM package to get the package for web:

npm run get-web-package --path=<OPTIONAL_PATH>

• If the --path option is set, it will put the files for web there.
• You will find those files in ./dist folder instead.

Use the PDFix SDK accordingly:

// replace with your import path
import { Pdfix as PdfixSdkWrapper, PdfixSdk } from './assets/pdfix/index';
import { Pdfix, PdfDoc } from 'PDFIX_WASM';

const pdfixSdkWrapper: PdfixSdkWrapper = new PdfixSdkWrapper();
// provide your "helper" path ('/assets/pdfix/') if your
// web app cannot find wasm binary
pdfixSdkWrapper.loadPdfixSdk('/assets/pdfix/').then(() => {
  const pdfixSdk: PdfixSdk = pdfixSdkWrapper.getPdfixSdk();
  const pdfix: Pdfix = pdfixSdk.GetPdfix();
  const pdfDoc: Promise<PdfDoc> = pdfixSdkWrapper.openDocumentFromUrl('<YOUR_DOCUMENT_URL>');

  // your code ...

  pdfix.Destroy();
});

TypeScript Declaration File & Documentation

The package comes with a TypeScript Declaration File (d.ts) for the pdfix_wasm module. Thus it is recommended to get started with a TypeScript based project. To get more details about any of the functions in the SDK, check in our Documentation

Powerful Solutions

We want to show the world that it is possible to take advantage of all the amazing features that PDF has available without the headache of having to understand them yourself.

Make PDF Accessible

Make your PDFs PDF/UA compliant in ease.

const pdfDoc: PdfDoc = pdfix.openDocumentFromPath('<YOUR_DOCUMENT_PATH>');
const pdfAccessibleParams: PdfAccessibleParams = new pdfixSdk.PdfAccessibleParams();
pdfDoc.MakeAccessible(
  pdfAccessibleParams,
  "Document Title",
  "en-US",
  0,
  0
);
pdfDoc.Close();

Add Tags to PDF

Improve Accessibility in Existing PDF Files.

const pdfDoc: PdfDoc = pdfix.openDocumentFromPath('<YOUR_DOCUMENT_PATH>');
const pdfTagsParams: PdfTagsParams = new pdfixSdk.PdfTagsParams();
pdfDoc.AddTags(pdfTagsParams, 0, 0);
pdfDoc.Close();

PDF to HTML, PDF to Responsive HTML

Easily convert any PDF into HTML.

function streamToString(sdk: PdfixSdk, stream: PsStream): string {
  const ptr: number = sdk._malloc(stream.GetSize());
  stream.Read(0, ptr as any, stream.GetSize());
  let string: string = '';
  for (let i = 0; i < stream.GetSize(); i++) {
    string += String.fromCharCode((sdk as any).HEAP8[ptr + i])
  }
  return string;
}

const pdfDoc: PdfDoc = pdfix.openDocumentFromPath('<YOUR_DOCUMENT_PATH>');
const pdfToHtmlConversion: PdfHtmlConversion = pdfDoc.CreateHtmlConversion();
let pdfHtmlParams: PdfHtmlParams = new pdfixSdk.PdfHtmlParams();
pdfHtmlParams.flags |= (
  PdfixEnum.kHtmlNoExternalCSS |
  PdfixEnum.kHtmlNoExternalJS |
  PdfixEnum.kHtmlNoExternalIMG |
  PdfixEnum.kHtmlNoExternalFONT
);
pdfHtmlParams.type = PdfHtmlType.kPdfHtmlResponsive;
pdfToHtmlConversion.SetParams(pdfHtmlParams);
pdfToHtmlConversion.AddPage(1, 0, 0);
const stream: PsStream = pdfixSdk.GetPdfix().CreateMemStream();
pdfToHtmlConversion.SaveToStream(stream, 0, 0);
const htmlString = streamToString(pdfixSdk, stream);
stream.Destroy();
pdfToHtmlConversion.Destroy();

console.log(htmlString);
pdfDoc.Close();
