Question 1

How much can I compress a PDF?

Accepted Answer

File size reduction depends on the content. Image-heavy PDFs can be reduced by up to 90%. Text-heavy PDFs with the "Light" option preserve selectable text with moderate reduction.

Question 2

Will compression affect PDF quality?

Accepted Answer

The "Light" and "Minimal" options preserve text quality. The "Maximum" and "Balanced" options render pages as images, which reduces quality but achieves much smaller file sizes.

Question 3

What compression levels are available?

Accepted Answer

Four levels: Maximum compression (renders as images), Balanced (renders as images), Light (strips metadata, keeps text), and Minimal (re-save only, keeps text).
