Frequently Asked Questions

What is the difference between Reduced Size PDF and Optimized PDF?

Reduced Size PDF applies a standard set of automatic compression algorithms to quickly shrink the file. Optimized PDF allows you to manually adjust granular settings, such as color and grayscale image downsampling, font un-embedding, and discarding specific document objects.

Will reducing the PDF size affect the image quality?

Yes, standard compression works primarily by lowering the resolution of images within the document. While text remains sharp, photographs and detailed graphics may become noticeably blurrier.

Can I reduce the size of multiple PDFs at the same time?

Yes, if you are using Adobe Acrobat Pro, you can apply the Reduced Size PDF command to multiple files simultaneously by using the Action Wizard feature to batch process the documents.
