How to Rename Multiple Images
Batch renaming images is perfect for organizing photos, product catalogs, or any collection of images that need consistent naming. Our tool uses pattern templates with powerful tokens that automatically generate unique filenames.
Quick Start Guide:
- Upload your images using the drag-and-drop area or file browser
- Go to the “Rename” tab and create your pattern using tokens like {n}, {original}, {date}
- Preview the new filenames and check for any collisions
- Move to the “Resize” tab to configure dimensions (optional)
- Click “Process Images” and download as individual files or ZIP
