How to use it

Honest note: At these settings each page is rendered as an image. That produces large savings on scans and image-heavy PDFs, but selectable text becomes part of the image and will no longer be copyable or searchable. Keep your original PDF if you need searchable text.

Choose 72 DPI for a quick email copy, 100 DPI for everyday sharing, or 150 DPI when small text must stay crisp.
Lower JPEG quality shrinks the file further but softens fine detail.
Always spot-check a dense page in the result before sending it.
