Hi,
I’m using aspose .net pdf version 18.5.0.0 to convert a pdf with high resolution images. The images are compressed with LZW and the initial file size of the pdf is 28mb. When I convert it to PDF_A_3A the new file is 400mb. As I understand the LZW compression is not supported in PDF/A. Is there any way to optimize the images size?
Thank you.
