WHAT YOU CAN DO
Optimize PDF File Size: what you need to know
PDFs can contain duplicate structures or internal objects that can be reorganized. Prisma Space attempts to optimize that structure while maintaining the selectable content of the document.
This option does not recompress photographs and does not promise a large reduction in all cases. A PDF composed mainly of images may remain almost as heavy.
STEP BY STEP
How to use this tool
- Select the PDF document you want to optimize.
- Run the optimization of its internal structure.
- Compare the size of the downloaded file with the original.
