Common questions
Why does compression flatten the pages?
The tool rebuilds each page as a compressed picture. This is effective for scanned or image-heavy PDFs, but selectable text and clickable links will not remain.
Why did my PDF not get smaller?
Some PDFs are already highly compressed or contain mostly simple text. In that case, rebuilding the pages may not create a smaller file.
