How to Rename Multiple Photos on iPhone
Here is the first surprise: the iPhone Photos app cannot rename your photos. There is no rename option on a photo in the camera roll, only captions and albums, so the underlying filename stays IMG_3847.jpg no matter what you do inside Photos. To actually change the name, you go through the Files app instead.
Save or move the photos you want to rename into a folder in the Files app, either in iCloud Drive or On My iPhone. Open that folder, touch and hold a photo, and tap Rename. Type the new name, keeping the .jpg or .heic extension on the end, and confirm. That is the whole method, and it works on any iPhone without installing anything.
The catch is that Files renames one photo at a time. There is no select-all, type-a-name, and number-them-all option the way a desktop has. So renaming multiple photos at once on iPhone really means renaming them one by one, which is fine for three photos and miserable for three hundred. That one-by-one grind is exactly the pain that pushes people toward a tool that can name a whole batch in a single pass, especially when the names should describe the photos rather than just count them.
How to Rename Multiple Photos on Android
Android gives you real file access, so renaming is more direct than on iPhone. Open Files by Google, or the stock file manager that came with your phone, and browse to the DCIM or Camera folder where your photos live. Touch and hold a photo to select it, tap the three-dot menu, and choose Rename. Type the new name and confirm.
You can select multiple photos at once in most Android file managers, but selecting many and then choosing rename usually still walks you through them one at a time, since the built-in rename is designed for single files. A few file managers and third-party apps add a true bulk rename with numbering or find-and-replace, but that is not something you can count on being present out of the box, so check what your specific phone offers.
One warning that matters more on Android than anywhere else: keep the file extension. When you rename, the field often shows the full name including .jpg, and it is easy to delete the .jpg by accident. A photo without its extension can stop opening in the gallery, so always leave the .jpg, .jpeg, or .heic on the end. If you want names that describe what is in each shot rather than a manual sequence, a content-aware tool handles the whole camera folder at once without you touching each file.
How to Rename Multiple Photos on Windows
Windows has a genuinely good built-in batch rename, and it is worth knowing. Copy your photos off the phone into a folder, open that folder in File Explorer, and select all the photos you want to rename with Ctrl+A or by dragging a box around them. Press F2, type one base name, and press Enter. Windows renames the whole selection to that base name and appends a number in parentheses: vacation (1).jpg, vacation (2).jpg, vacation (3).jpg, and so on. That is the fastest way to rename multiple photos in Windows 11 or Windows 10 with zero extra software.
When you need more than sequential numbering, install PowerToys, Microsoft's free official add-on, and use its PowerRename tool. Right-click your selected photos and choose Rename with PowerRename. It gives you find-and-replace across every filename, real numbering patterns, case changes, and a live preview that shows exactly what each file will become before you commit. It is honestly one of the best free batch rename tools on any platform, and it costs nothing.
What both methods share is that they rename by pattern. Whether it is a base name plus a number or a find-and-replace rule, the new names come from the text you type, not from the pictures. That is perfect when your photos are already sorted and you just want them numbered cleanly, and it is no help at all when you want each name to say what is in that particular photo.
How to Rename Multiple Photos on Mac
The Finder on Mac has a strong native batch rename that many people never notice. Copy your photos into a folder, open it in the Finder, and select all the photos you want to rename. Right-click the selection and choose Rename, and the Finder shows a small panel with three modes for how to batch rename photos on Mac in one go.
Replace Text swaps one piece of text for another across every selected filename, which is ideal for cleaning up a common prefix. Add Text puts a word or label before or after each name. Format renames everything to a base name plus an index or counter, so you get Vacation 1.jpg, Vacation 2.jpg, and up, with control over where the number starts. You pick a mode, fill in the fields, and the Finder applies it to the whole selection at once.
It is a fast, reliable, completely free tool, and for renaming by pattern it is all most people need. Like every native tool, though, it renames from what you type. The Finder will happily number your beach photos and your whiteboard photos and your receipts into one clean sequence, but it has no idea which is which, because it never looks at the images.
The Limit of Native Tools, and the Content-Aware Fix
Notice the pattern across all four operating systems: iPhone Files, Files by Google, Windows File Explorer and PowerRename, and the Mac Finder all rename photos by pattern. They add a base name and a number, they find-and-replace text, or they stamp a date. Every one of them is free, and the desktop ones are genuinely capable. What none of them can do is name a photo by what is in it, because none of them look at the picture. That is the real limit, and it is why a folder renamed to vacation_001.jpg through vacation_300.jpg is tidier but no easier to search than IMG_3847.jpg was.
This is where content-aware naming comes in. Renamer.ai uses AI computer vision to read each image and write a filename from what it sees, the subject, the scene, the people, and any visible text, so a beach shot becomes beach_sunset_family_photo.jpg and a whiteboard photo becomes whiteboard_q3_roadmap.jpg. You drop in the whole batch, review the suggested names in a preview, and confirm, and it is free to start with no credit card. If pattern renaming is not solving your problem, the AI photo renamer is the tool to reach for, and you can read more about how it works on the photo renamer page.
The two approaches are not rivals so much as different jobs. When your photos are already organized and you just want them numbered, the native tool on your device is the fast, free answer. When the problem is that you cannot tell one IMG file from the next without opening it, naming by content is the fix a pattern rename was never built to provide.
