1. File Upload
Upload the files you want to rename. Files with the exact same name are automatically skipped. You can reset the list and settings anytime using the "Clear all files and settings" button.
2. Change Rule Settings
Switch tabs to perform various operations when renaming file names.
Add Date
Select the date format to append to the file name.
- File modified date: Add the file's last modified date
- File modified time: Add the file's last modified date and time
- Current date: Add today's date
- Current time: Add today's date and time
* If you want to add a date in a custom format, please use the "Add Text" feature.
Add Text
Add custom text to the file name in bulk.
Replace Text
Replace a specific string with another string.
You can apply multiple conditions at the same time using the "+ Add replacement condition" button.
Add Sequential Numbers
Add sequential numbers to files. You can sort by order (such as by file name or modified date) before numbering.
- File name (ascending/descending)
- Modified date (ascending/descending)
Open the advanced settings to fine-tune the format, such as "Start from 0" or "Zero padding (001, 002...)".

You can choose to add the text at the "Prefix", "Suffix (before extension)", or "After extension".
