Hi all,

I have been looking around, however it does not seem to have an effective way to open an existing PdfLoadedDocument and convert everything in it (text, images, etc.) into grayscale. In my hand there is such a request to programmatically convert an existing PDF to black and white. Is this even possible using Syncfusion libraries?

Hi Patrick,


Thank you for using Syncfusion Product.


It is not possible to change the Color of the text i.e. to Grayscale, but it is possible to change the color of the images in the PDF document.


Please let us know if you have any questions.

Hi Fabian, 
Currently we do not have support for changing the text color to grayscale in existing PDF document, we have already added it to our feature request list. it will be implemented in one of our releases. The feature implementation greatly depends on product design, code compatibility and complexity. We request you to visit our website periodically for feature updates.
