With certain types of images, such as scanned text-based documents, there are 2 ways to produce small size files using LEADTOOLS:
1. If the image contents are mainly text with very good quality and high resolution, perform OCR to convert the image contents to text and save the result as document (searchable text) PDF. In most cases, searchable text takes smaller disk size than images.

2. If the image is not suitable for OCR, you can use the LEADTOOLS PDFFile class to produce small size images in output PDF, such as using JBIG2 compression. This is implemented in the PDFFile demo shipped with the toolkit:
[LEADTOOLS 19]\Shortcuts\PDF\.NET Class Libraries\PDF File

The PDFFile class uses the Optimize() method with the PDFOptimizerOptions Class to set new options for the PDF file and save the result. More details are in these help topics:
