Hi Team,
My requirement is that we have a byte[] (byte array) and i want it to convert pdf but io am not getting such code that fulfill my requirement. Please help to provide me sample code for byte array to pdf conversion.
Please note that API provides only following document loading options:
- Load document from Amazon S3 Storage
- Azure Blog
- FTP
- Local Disc
- Stream
- URL
However, we have logged this scenario in our internal issue tracking system with ID: CONVERSIONJAVA-800. We’ll now further investigate it and let you know if this is possible.
Thanks Team so further can you please provide the code for Stream to .pdf conversion and after that i want to download this file in java .
please assist me asap i am stuck on that

Please go through this documentation and this API reference.
Below is the sample code:
PdfSaveOptions saveOption = new PdfSaveOptions();
String guid = "D:/conversion/Data/SourceFiles/demo.docx";
FileInputStream fileStream = new FileInputStream(guid);
ConvertedDocument convertedDocumentPath = conversionHandler.<String> convert(fileStream,saveOption);
You have to write your own logic to download the file. API just generates output in a specified folder.
Please see if this can help:
InputStream inputStream = new ByteArrayInputStream(data);
ConvertedDocument convertedDocument = conversionHandler.convert(inputStream, new PdfSaveOptions());
convertedDocument.save("converted from byte array.pdf");
inputStream.close();Hi Team,
Can you please provide the code how to create ConversionHandler object.
Please tell me how to create ConversionHandler object and how to get Configuration object .
Actually i am using below code , but getting performance issue can you pls help on below code :
ConversionHandler conversionHandler = new ConversionHandler(Utilities.getConfiguration());
PdfSaveOptions saveOption = new PdfSaveOptions();
saveOption.getPdfOptions().getFormatingOptions().setPageMode(PdfFormattingOptions.PdfPageMode.FullScreen);
saveOption.getPdfOptions().getFormatingOptions().setPageLayout(PdfFormattingOptions.PdfPageLayout.SinglePage);
byte[] bytearr = html.getBytes();
ConvertedDocument convertedDocument= conversionHandler.convert(new ByteArrayInputStream(bytearr),fileName,saveOption);
GroupDocsOutputStream groupDocsOutputStream = new GroupDocsOutputStream(response.getOutputStream());
convertedDocument.save(groupDocsOutputStream);
// this is my configuration method from utilities class
public static ConversionConfig getConfiguration(){
//ExStart:getConfiguration
try{
// Setup Conversion configuration
ConversionConfig conversionConfig = new ConversionConfig();
return conversionConfig;
}
catch (Exception exp) {
System.out.println("Exception: " + exp.getMessage());
exp.printStackTrace();
return null;
}
//ExEnd:getConfiguration
}

Can you please further elaborate this?
What we understand is that you want to see how to instantiate ConversionConfig to set conversion configuration and how to create instance of ConversionHandler class to convert between different file formats, right?
If yes, please go through following resources:
- Conversion configuration
- Conversion handler
- Configuration implementation
See code below:
ConversionConfig conversionConfig = new ConversionConfig();
conversionConfig.setStoragePath(storagePath);
conversionConfig.setOutputPath(outputPath);
// Instantiating the conversion handler
ConversionHandler conversionHandler = new ConversionHandler(conversionConfig);
If you give us more details, we can assist you accordingly.
Hi Team,
I don’t want to use below code bcs in my case i am only wants to download that converted pdf file so there is no need to take storagePath and outputPath
Please assist me in that case what i can do :
conversionConfig.setStoragePath(storagePath);
conversionConfig.setOutputPath(outputPath);
Please note that API doesn’t provide any feature to download the file. It only allows you to save the output. These are the ConversionConfig method details.
There are two options:
- Save resultant file to output folder
- Save result in a stream and then utilize it as per your needs (this may meet your requirements)
Please visit this article and see how to store result in a IO stream.
Hi Team,
I am trying to use below code sample but getting exception
ConversionHandler conversionHandler = new ConversionHandler(new ConversionConfig());
InputStream inputStream = new ByteArrayInputStream(data);
ConvertedDocument convertedDocument = conversionHandler.convert(inputStream, new PdfSaveOptions());
GroupDocsOutputStream groupDocsOutputStream = new GroupDocsOutputStream(response.getOutputStream());
convertedDocument.save(groupDocsOutputStream);
inputStream.close();
when i execute this code below exception occured!

_ at com.sdgc.truops.policy.document.CommonConversion.convertToPdf(CommonConversion.java:65)_
I think i am not set proper implementation of ConversionConfig bcs i called it without setting any path bcs i no need to set storage path, cache path etc

Please tell which API version (e.g. 10.6, 19.10) you are using? Make sure data size is greater than 0.
Also, can you please share a simple console application using that we can reproduce the issue?
Hi Team,
I am using below dependency
com.groupdocs
groupdocs-conversion
19.4
My Sample code example given below !
public void convertToPdf(String policyId,Integer documentId,ServletContext context,ServletOutputStream outputStream,HttpServletResponse response, String pageFlag) throws UnsupportedEncodingException, Exception {

We are not able to reproduce this issue using API version 19.10 and code below.
