Choosing a PDF compression method
PDFs containing scanned pages or large images may respond differently from text-based documents. Image-based compression can reduce file size by rendering pages as images, but selectable text, links, forms and accessibility information may be lost. Keep the original and inspect every page of the compressed copy.
