Frequently Asked Questions

How does PDF compression work?
This tool renders each page as a JPEG image at your chosen quality, then reassembles into a new PDF. Lower quality = smaller file size.
Will text remain selectable?
Text becomes rasterized (image). For PDFs with selectable text, this trades searchability for smaller file size.
