Why your business site needs a PDF to HTML converter?

In this section, we will look into the business perspective of having a PDF to HTML converter in our business app. There is a user-friendly live editor where you can test the feature here. Therefore, always feel confident to opt for Aspose.PDF APIs due to the following reasons.

Aspose.cloud APIs & SDKs are Secure

It is the most important factor when it comes to integrating a third-party library into our business application. However, Aspose.cloud is equipped with an enterprise-level security mechanism. There is a dashboard where it lets you generate API credentials that include an API key and API secret. These credentials are then used to make API calls and for the editor.

In-House Data Processing

When it comes to enterprise users, it adds value to your business application when customers are given a live editor to convert data files into a different file format. In addition, Aspose.PDF also offers cloud storage where users can save files.

SEO Friendly

Search engine optimization is a very serious component of an online business. However, Portable Document Format(PDF) is not SEO friendly. Therefore, converting your PDF files to HTML files always gives you a competitive edge in terms of rankings in popular search engines.

Lightweight

Another important perk of having HTML files is that HTML files are lightweight as compared to PDF files. Therefore, managing PDF files is comparatively storage efficient.

Rapid Development

As far as software development is concerned, you can boost up your development by leveraging this PDF to HTML converter. Moreover, you can configure this file conversion software as per your preferences.

    const pdfApi = new PdfApi(
      'YOUR-APPSID',
      'YOUR-APPKEY',
    );
    try {
      const data = fs.readFileSync(name);
      await pdfApi.uploadFile(SrcFile, new Buffer(data), storageName);
      await pdfApi.putPdfInStorageToHtml(
        name,
        resultPath,
        null,

        'zip',
      );
      // Download pdf from cloud storage
      const fileData = await pdfApi.downloadFile(resultPath, storageName, '');
      const writeStream = fs.createWriteStream(fileToWrite);
      writeStream.write(fileData.body);
