Code for PNG to WEBP Conversion in Java Low Code API

String ClientID = Client.getID(); //replace Client.getID() with your own client ID here
String ClientSecret = Client.getSecret(); //replace Client.getSecret() with your own client secret here
String APIBaseUrl="https://api.aspose.cloud";
String Local_Path = "C:/Temp/";
ImagingApi imagingApiSdk = new ImagingApi(ClientSecret, ClientID, APIBaseUrl);
// Input & output file names
String inputFileName = "PNGtoWEBP.png";
String outputFileName = "PNGtoWEBP.webp";
try {
// Upload local image to Cloud Storage
File inputFile = new File(Local_Path + inputFileName);
FileInputStream inputFileStream = new FileInputStream(inputFile);
byte[] inputImageData = IOUtils.toByteArray(inputFileStream);
UploadFileRequest uploadFileRequest = new UploadFileRequest(inputFileName, inputImageData, null);
FilesUploadResult filesUploadResult = imagingApiSdk.uploadFile(uploadFileRequest);
String outputFormat = "webp";
String remoteFolder = null; // Input file is saved at the root of the storage
String remoteStorage = null; // Cloud Storage name
ConvertImageRequest convertImageRequest = new ConvertImageRequest(inputFileName, outputFormat, remoteFolder, remoteStorage);
byte[] convertedImageData = imagingApiSdk.convertImage(convertImageRequest);
// Save exported image to local storage
FileOutputStream fileOutputStream = new FileOutputStream(Local_Path + outputFileName);
fileOutputStream.write(convertedImageData);
fileOutputStream.close();
} catch (Exception e) {
System.out.println(e.getMessage());
