Upscale makes a photo 4K: 3840 pixels on the long side. Use it on a staged or edited photo you made at 1K preview resolution, once you're happy with it.
Steps
- Hover the photo on the Photos tab and click Upscale. You can also use the Upscale button at the top of the Photo Edit and Virtual Staging pages.
- Read the confirmation, Upscale to 4K?, and click Upscale.
- Wait about 20–40 seconds. You'll see Upscaled to 4K when it's done.
When Upscale isn't available
- The button is greyed out on photos that are already 4K or larger. The tooltip shows the current size.
- RAW files can't be upscaled. Merge them first.
