Questions
Which PDFs get much smaller?
Scans and PDFs made from photos: they are mostly pictures, and pictures shrink 3–10 times. A PDF that is only text is already small and changes little.
Will the text stay sharp and selectable?
Yes: only the pictures inside are saved again. Text, fonts, links and drawings are left exactly as they were.
Can I compress a password-protected PDF?
No: remove the password first (open the file and save a copy without it), then compress the copy.
Is the file uploaded?
No. The PDF is compressed in your browser on your device.
