I had an album full of photographs of the contents of an old travel trailer I used to live in. I also had an album full of photographs of the flying history museum that I wanted to keep. Do I need to look at them all the time? No. Do I want to keep them? Yes.
When I realized I could drag and drop them into a Keynote presentation, I found I could do that for most of my photographs stored in Apple Photos. I’m down to 62 photographs and that’s it.
Does Keynote store those photographs without modifying them?
(No compression or anything like that?)
I don’t think so, as there is a command to “Reduce File Size” in Keynote.
From DuckDuckGo AI:
Keynote and Image Storage
Original Images
Keynote automatically saves your presentation and keeps the original images unchanged when you add them to your slides. This means that any photographs you import into Keynote are stored without modification.
However, I saw a warning message for the first time, stating that lower resolution images would be added, and to export first to the file system, then import to the presentation. Interesting…
I would always store any data as close to the original as possible unless there are concerns over longevity (proprietary formats) or privacy (reducing the risk or revealing personal data included in the original file) when PDF is my go to.
JPG and HEIC/F are now ubiquitous with very little evidence of a move away, and the EXIF data within them are valuable and worth maintaining.
Of course YMMV, so do you.
I don’t trust AI, so I did an experiment myself:
.key to .zipdiff on the original PNG and the one in the “zip file”Files are identical!
This doesn’t prove it’s true for any image (type), but it’s something…
