Check the output before using it. Complex formatting, fonts, or embedded objects may differ from your original.
A few helpful answers.
Why is my PDF not smaller?
Some files are already optimized or contain mostly text. If the generated result is larger, the tool keeps the original and explains that no size reduction was achieved.
