You want a photo name you can actually find later, or a real filename for uploads and folders. On iPhone, those are two different jobs.
The Photos app on iPhone lets you add searchable captions, and Photos on iCloud.com adds titles, while Files, Preview, iCloud Drive, external storage, and Shortcuts handle actual image filenames. Start with the option that matches where the image needs to live.
Add a searchable caption in Photos
Use this when the picture is staying in your Photos library and you want to search for it by name later. A caption is the closest built-in iPhone option to renaming a photo inside Photos, but it does not change the original IMG_#### filename.
Open Photos and open the photo or video.
Swipe up or tap the Info button.
Use the caption field to describe the photo or video.
Search for that caption later inside Photos. The same caption applies to iCloud Photos items.
Save the image with a filename in Files
Use Files when you need the image to carry a real filename outside the Photos library.
- 1.Open Photos and open or select the photo.
- 2.Tap the Share button.
- 3.Choose Save to Files and pick a folder in On My iPhone, iCloud Drive, or a supported file provider.
- 4.Open Files and go to the folder where you saved the image.
- 5.Touch and hold the image file, tap Rename, enter the new name, then confirm the change.
Change the filename in Preview
Preview on iPhone requires iOS 26 or later; on earlier versions, rename the saved file in Files instead. Preview renames image files and PDFs opened in the app. It works on files, not on originals that exist only inside the Photos library.
Open Preview and open the image file. Tap the Actions Menu button next to the filename.
Choose Rename, enter the new filename, then tap Done. The renamed item remains a file, separate from the original Photos-library item.
Export the original to external storage
For a photo headed to a connected drive or memory card, export the original first. Connect the storage device, open Photos, select the photos and videos, tap the Share button, then choose Export Unmodified Original.
Tap your storage device under Locations, then tap Save. Open Files, go to the storage device location, touch and hold the exported image file, tap Rename, and enter the new name.
If this method fails, save the photo to On My iPhone or iCloud Drive in Files, then rename the saved file there. Finish the job by touching and holding the renamed file, tapping Move, then choosing the connected storage device under Locations.
Build a shortcut for repeat renames
Use this when you rename or export photos often and want the same workflow ready every time. A shortcut can set a custom name for an image output and save it as a file.
Open Shortcuts, tap the Add button, then choose New Shortcut.
Tap Rename, enter a shortcut name, tap Done, then tap Add Action.
Add actions that select or get a photo.
Place Set Name before the next action, then add Save File.
Run the shortcut to create a renamed file output. The original item inside Photos keeps its underlying filename.
Start the shortcut with Siri
Siri can run any shortcut in your collection, including the photo-renaming shortcut you created in Shortcuts.
Say the shortcut's name to Siri, then follow the prompts. If the shortcut asks for a filename, dictate the name when prompted, and the rename still comes from the shortcut's Set Name and Save File actions.
If this method fails, open Shortcuts and run the same shortcut manually before starting it with Siri again.
Dictate the new name
Open Settings.
Go to General.
Open Keyboard.
Turn on Enable Dictation.
When editing a caption or filename in Photos, Files, or Preview, tap the text field and use Dictation from the keyboard.
Keep names short and specific so they stay easy to search, share, and recognize.
Edit names from iCloud in a browser
This fixes browser-based naming for photos and image files already in iCloud.
For iCloud Photos, go to icloud.com/photos and sign in to your Apple Account.
Tap or double-click the photo or video.
Tap the Info button.
Tap Edit next to Title and caption.
Enter the text, then tap Save.
For an image file in iCloud Drive, go to icloud.com/iclouddrive, select the image file, tap the More button in the top-right corner, choose Rename, and enter the new name.
Skip album and People names
Some Photos labels sound like photo renames, but they change something else. In Photos, renaming an album changes only the album title, not the photos inside it.
The People & Pets tools name a detected person or pet for search and collections. They do not rename the photo file.
Apple supports two clean routes here: add searchable metadata inside Photos or export the image and rename the file in Files, Preview, iCloud Drive, or external storage.
Frequently Asked Questions
Can I rename the original IMG_#### photo inside the iPhone Photos app?
No. iPhone Photos does not include a supported control for renaming the original filename directly in the Photos library. Add a caption for search, or export the photo and rename the saved file.
What is the closest thing to renaming a photo in Photos?
Add a caption in Photos, or add a title and caption through iCloud Photos in a browser. Those labels help with search and organization, but they are metadata, not filename changes.
Does renaming a file in Files change the photo in Photos?
No. Files renames the exported or saved image file. The original item in the Photos library keeps its own underlying filename.
Can Siri rename iPhone photos?
Siri can run a shortcut that sets a name and saves an image file. Siri does not rename the original Photos-library item by itself.
Can I rename a photo on external storage from my iPhone?
Yes. Export the unmodified original to the connected storage device, open that location in Files, touch and hold the image file, then use Rename.
