Try to convert PDF to JPEG online

Aspose.PDF for Node.js presents you online free application “PDF to JPEG”, where you may try to investigate the functionality and quality it works.

Convert PDF to JPEG

In case you want to convert PDF document, you can use AsposePdfPagesToJpg function. Please check the following code snippet in order to convert in Node.js environment.

CommonJS:

Call require and import asposepdfnodejs module as AsposePdf variable.
Specify the name of the PDF file that will be converted.
Call AsposePdf as Promise and perform the operation for converting file. Receive the object if successful.
Call the function AsposePdfPagesToJpg.
Convert PDF file. Thus, if ‘json.errorCode’ is 0, the result of the operation is saved in “ResultPdfToJpg{0:D2}.jpg”. Where {0:D2} represents the page number with a two-digit format. The images are saved with a resolution of 150 DPI. If the json.errorCode parameter is not 0 and, accordingly, an error appears in your file, the error information will be contained in ‘json.errorText’.


  const AsposePdf = require('asposepdfnodejs');
  const pdf_file = 'Aspose.pdf';
  AsposePdf().then(AsposePdfModule => {
      /*Convert a PDF-file to JPG with template "ResultPdfToJpg{0:D2}.jpg" ({0}, {0:D2}, {0:D3}, ... format page number), resolution 150 DPI and save*/
