Batch renaming allows you to change the names of multiple photos simultaneously on your device, instead of editing each one individually. Unlike manual renaming, it applies a single naming rule, pattern, or prefix/suffix to a selected group of photos. This action usually happens within the phone's file management system or gallery settings.

You can typically do this using your phone's built-in tools. On iOS, select photos in the Photos app or use the Files app for deeper storage management. Many Android devices offer a similar option within the Google Files app or the manufacturer's gallery app when selecting multiple items. For instance, you might rename vacation pictures from untitled defaults to "Hawaii_Trip_001.jpg," "Hawaii_Trip_002.jpg," and so on. Mobile tools are usually simpler than desktop software.

This saves significant time organizing large photo collections after events or shoots. However, mobile options often lack advanced features like custom numbering sequences beyond basic prefixes/suffixes, template variables (like date/time), or processing RAW files reliably. It's important to understand the tool you use to ensure it preserves essential EXIF metadata during renaming. Mobile functionality continues to improve but still focuses on basic, user-friendly renaming.
