To convert a Pages file into a PDF document:
1. Open the file then choose File --> Export to --> PDF.
2. Click Next and type the name of the file. You don't have to include .pdf as this is automatically added.
3. If there's a password checkbox, you can set a new password, keep the password from the original document, use a different password for your exported PDF, or uncheck the "Require password to open checkbox".
4. To choose where to save it, click on the Where pop-up menu, pick a location, then click Export.
