Before you export

Build a naming plan before the folder gets messy

A useful batch rename starts with the way the files will be searched later. For a photo set, that might mean a project name followed by a sequence. For monthly reports, it may be a department, reporting period, and version. Decide the stable pieces first, then remove camera codes, draft markers, or inconsistent capitalization that no longer helps.

Apply operations in a deliberate order because each rule receives the result of the previous one. Replace unwanted text before adding a prefix, normalize the case before numbering, and keep the extension untouched unless changing it is genuinely part of the job. The live preview makes that order visible before anything is exported.

Guide

A simple batch rename workflow

Start with the files you want to organize, then add only the rules that solve the naming problem. A preview gives you a chance to catch unintended replacements before you download the renamed files.

Start with one rule

Apply a simple prefix or replacement first, then add more rules only when needed.

Number in order

Sequential numbers make related assets or documents easy to scan.

Use the preview

Review the final names before exporting to avoid duplicates or unclear labels.

Frequently asked questions

What is batch rename?

Batch rename applies a shared naming rule to several files in one workflow.

Can I add numbers to filenames?

Yes. Add a sequential numbering rule and preview the result before export.

Will this change file contents?

No. The tool changes filenames and packages the original file contents into a ZIP.
