Which settings should I start with?
Use the following as a first preset for finished photos you want in Apple Photos on your phone. You can use the same choices in LR to Photos’ publish settings or Lightroom Classic’s regular Export dialogue.
| Setting | Suggested starting point |
|---|---|
| Image Format | JPEG |
| Color Space | sRGB |
| Quality | 80–90; inspect a sample before committing to a larger batch |
| Image Sizing | Full pixel dimensions, or try Resize to Fit → Long Edge at 3,000 pixels when smaller files matter |
| Enlargement | Use Don’t Enlarge when resizing if you want to avoid increasing smaller images |
| Metadata | Include the information you want to carry into Photos; review location information before sharing |
There is no single quality number or pixel size that suits every photograph. These suggestions are an editorial starting point, not the result of a file-size or phone-display comparison. Adobe explains each export control.
Why use JPEG for this workflow?
A JPEG export renders your Lightroom adjustments into a finished image that you can view and share. It is a straightforward choice for the phone copies in this guide.
Choose JPEG rather than Original when you want the visible Lightroom edit in the exported file. Your original files remain where they are, and you can continue editing them in Classic. You are choosing the format of a separate sharing copy.
sRGB is a conventional starting point for this sharing workflow. It is not an Apple Photos requirement, and it does not guarantee that every app or display will show an image identically.
Should I resize or keep full resolution?
Keep Resize to Fit off when you want the available exported pixel dimensions and more flexibility for a later crop or another use. This is a simple default when file size is not your main concern.
If the copies are primarily for phone viewing and sending to friends, try a smaller long edge. 3,000 pixels is one starting point to compare with a full-size export. Examine fine detail and any crop you expect to make before deciding.
Pixel dimensions control the amount of image detail in the file. Changing the pixels-per-inch resolution value alone does not add detail to the version on your phone.
How can I keep the copies smaller?
Choose only the pictures you want on your phone, then adjust pixel dimensions and JPEG quality. A smaller image and more compression can reduce file size, with tradeoffs in detail or visible compression. The actual size depends on the picture, so check the exported files rather than assuming a fixed amount per image.
Sending selected JPEGs means this workflow does not require uploading your Lightroom original files to Photos. Those JPEGs still take space in your Photos and iCloud libraries. Later published versions can also add storage while older copies remain; see how to review older versions.
What should I check before publishing a full album?
- Choose a few representative finished images, including one with fine detail and one you might crop.
- Publish or export them with your starting settings.
- Open the copies in Photos on your iPhone. Check their appearance at normal viewing size and when zoomed.
- Check the file sizes and any metadata you care about, such as capture date and location.
- Adjust one setting at a time if the result needs more detail or smaller files, then keep the settings you prefer.
Once the result suits your pictures, reuse those choices for future publishing. The plugin setup guide shows where to configure the service; the manual export guide covers the free export-and-import route.
