Questions
Will compression always make the file smaller?
No. A PDF that is already compact may stay about the same size, or grow slightly. The page compares the two sizes.
What is the difference between the three options?
Smaller and Standard try to keep the original PDF. Smallest redraws pages as images, which is often smaller and the text can no longer be selected.
Is the PDF uploaded to compress it?
No. Compression runs in this browser.
