PDF size questions
Why did my PDF not become much smaller?
Some PDFs are already optimized, while scanned or image-heavy files have less room for invisible reduction.
Can I use this before signing?
Yes, but for final documents it is often better to compress after all pages and signatures are in place.
Is the result a normal PDF?
Yes. The downloaded file is a PDF that can be opened, sent, or uploaded like any other PDF.
