The Photos app has built-in editing controls for light, color, filters, cropping, rotation, and other common picture adjustments.
- Open Photos and select the picture.
- Tap Edit.
- Use Adjust, Filters, or Crop to make the changes you want.
- Compare the edit with the original as you work.
- Tap Done to save.
Photos edits are normally nondestructive, so you can reopen the picture, tap Edit, and revert to the original later.
If the labels on your screen differ slightly, use Settings search or the app’s current menus to find the named feature. Apple sometimes moves controls between iOS releases, so follow the feature name rather than an unrelated setting with similar wording.
