Converting PDF to Tiff file Size

Aspose.PDF Product Family
1

Good Morning,

I am using the Aspose.Pdf Product Family for converting PDF to TIFF files. During my testing, I found that after converting PDF files to TIFF files, the size of the TIFF file is more than that of the PDF file. Is there any way we can reduce the size of the TIFF file during conversion? The size of the TIFF file is 5-6 times more than the PDF file.

Please advice.

Thanks,
Sachin

Hi Sachin,

Thanks for contacting support.

During PDF to TIFF conversion, please try using any value other than None from CompressionType enumeration and pass it to TiffSettings.Compression instance. Furthermore, in order to have more optimized output, you may consider changing ColorDepth from Default to any appropriate value. Please take a look over the following code snippet.

In case the problem still persists, please share the resource PDF files.

[C#]

// open document
Document pdfDocument = new Document("input.pdf");

// create Resolution object
Resolution resolution = new Resolution(300);

// create TiffSettings object
TiffSettings tiffSettings = new TiffSettings();
tiffSettings.Compression = CompressionType.CCITT4;
tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;
tiffSettings.Shape = ShapeType.Landscape;
tiffSettings.SkipBlankPages = false;

// create TIFF device
TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);

// convert a particular page and save the image to stream
tiffDevice.Process(pdfDocument, "output.tif");

Thanks for the respone.

I tried the above code but size of Tiff file is still larger than PDF file.

Is there any other option I can try.

Thanks,
Sachin

Hi Vallapallis,


Thanks for contacting support.

The scenario varies from file to file as it mainly depends upon the structure and complexity of input PDF file. However have you tried using the suggestions shared in my earlier post 594009 and in case you still face the issue, please share your resource files so that we can test the scenario in our environment. We are sorry for this inconvenience.
