Euan showed us how to group a selected number of photos into a single PDF document, which can be displayed as a slideshow in a reduced overall file size. Starting with the list view of full-size JPEGs (you will need to export from the Photos app), he selected a number and then right-clicking to get an action menu. He chose Quick Action, Create PDF. The resulting PDF was the selected group using the title of the first elected one, of course, with the suffix PDF in lieu of JPEG. Finally, Euan opened the document in Preview and then exported it to PDF and used the Quartz Filter option to Reduce File Size.
David M explained that WhatsApp keeps a full-size copy of any photo or video received. In the app, select “You” or the setting gear wheel, scroll down to the lost, and WhatsApp can opt to have all received photos and videos automatically saved to the Photos app. On the app’s same list, just below Chats, you can select Storage and data and then Manage storage. This list shows chat contacts. Select a contact to see all the photos and videos stored on WhatsApp. Select, with the option to Select All, and delete as required.
