We are utilizing the Aspose.PDF grayscale conversion process described here:
The grayscale conversion itself works as expected, but the resulting files are roughly 30x larger (ie, a 500 KB file turns into a 15 MB file).
Our files consist of a Word document that is saved as a PDF within Word itself, and a TIF file which is converted to PDF using Aspose. The Word PDF and the TIF PDF are then merged and saved into one PDF using Aspose. At this point, the merged PDF has the expected/appropriate file size. Once the grayscale operation is completed, the file size inflates significantly.
We’ve tried this operation using Aspose.PDF versions 18.6.1 and 21.4.0. Both versions exhibit the same behavior. Any advice would be appreciated!
