Batch Renamer Pro creates consistently named copies of a file collection using a shared prefix, sequential numbering, and zero padding. A sequence makes a set of scans, photographs, or exported documents easier to sort and hand off. The naming operation changes filenames rather than converting the file format; a renamed image remains the same kind of image. File organization is easier to verify when the naming rule and the expected output are clear before you begin. Work on copies and test a small set that includes unusual filenames as well as ordinary ones. Spaces, extensions, sorting order, and duplicate names can all influence the final result. Keep the originals until you have opened the downloaded files and checked their names. A well-planned naming convention should remain understandable to someone who did not create the original collection.

How to use this tool
- Use Select Files to add the source collection and review the listed filenames.
- Select the rows to change and choose Bulk Rename Selected.
- Set the shared prefix, starting number, and zero padding, then choose Apply Pattern.
- Inspect the renamed list, use Download ZIP, and extract the archive into a new folder to verify names and contents.
SEE IT IN PRACTICE
A worked example
Three image files; prefix invoice_; start 1; padding 3
invoice_001.jpg, invoice_002.jpg, invoice_003.jpg
With a fixed three-digit number, alphabetical sorting follows the sequence from 001 through 999, provided the prefix is the same.
Designing a naming rule that will last
A useful sequence includes enough context to identify the collection without making every filename unwieldy. For example, a project prefix plus a fixed-width number is often easier to sort than a mixture of names such as final, final2, and latest. Decide whether the number represents upload order, capture order, or a deliberate manual sequence before assigning it. Zero padding is especially useful when the destination sorts names alphabetically: 001, 002, and 010 remain in numerical order. Reserve enough digits for the expected future size of the collection.
Checking names separately from contents
Filename changes can make a collection look organized while silently associating the wrong content with a meaningful number. Review the first, last, and several middle items, especially if the source filenames use inconsistent numbering. Keep file extensions associated with their original formats, and avoid implying a conversion simply by changing a suffix. After downloading, extract the archive into a new folder and open sample files there. This confirms that the saved package, rather than only the on-page preview, has the intended names and usable contents.
When this tool is useful
- Organize a set of scanned receipts
- Prepare numbered project photographs
- Give exported documents a consistent handoff naming convention
Tips for a better result
- Compare the number of downloaded files with the input list and open a sample to confirm its contents still match the intended name.
- Use a stable naming convention with a meaningful prefix and enough digits for future additions. Consistent zero padding keeps numbered files in a useful alphabetical order.
- Keep the source and the settings used for this result together. That makes a later comparison or correction easier, especially when another person needs to reproduce the same outcome.
Frequently asked questions
Does renaming a file convert its format?
Renaming an extension does not convert a file. Preserve meaningful original extensions and check file order before assigning numbers that imply chronology.
Should I keep the original files?
Yes. Retain them until the downloaded result has been checked for both names and contents. A separate source folder also makes it easier to repeat the operation with a different convention if your requirements change.
How can I avoid confusing filename collisions?
Review the complete proposed list, use a distinct sequence where appropriate, and consider whether your destination treats letter case differently. Names that appear different in one environment may still collide in another.
