- Which margin should I use?
- 20 mm is a comfortable default for A4. Printing usually needs at least 10 mm so nothing is clipped; a wide 30 mm margin leaves room for handwritten notes.
- My document is landscape or sideways
- Margins are measured the way the page is read, not the way it is stored, so a rotated page still gets its margin on the side you picked.
- Password-protected PDFs
- Encrypted files cannot be rewritten. Remove the password in your PDF reader first, then run it through here.
- Is there a page limit?
- No limit in the tool. Very large files simply take a few seconds longer, since the work happens on your own machine.
