Hello, @ashokreddyd ,
Could you share the code example you are using to split a TIFF image?
I have successfully tested your sample using the code below:

var inputPath = @"R1_4840.tif";
using var image = Image.Load(inputPath);
if (image is IMultipageImage multipage)
{
    var pages = multipage.Pages;
    for (int i = 0; i < pages.Length; i++)
    {
        var page = pages[i];
        page.Save($"{inputPath}-{i}.png");
    }
}

Hi Denis,
Thanks for your timely response.
Please find the below code snippet.
TiffImage tiffImage = (TiffImage) Image.load(imagePath);
TiffImage output = null;
int counter = 1;
for(TiffFrame tiffFrame : tiffImage.getFrames()) {
tiffImage.setActiveFrame(tiffFrame);
if(output == null){
output = new TiffImage(TiffFrame.copyFrame(tiffImage.getActiveFrame()));
} else {
output.addFrame(TiffFrame.copyFrame(tiffImage.getActiveFrame()));
}
if(counter % ocrBatchSize == 0){
output.save(fileName.toString(), options);
fileName = Paths.get(getUUIDFileName(outputDirectory.toString(), “.tif”));
filePaths.add(fileName.toString());
output.close();
output = null;
}
counter++;
}
