File Renamer
Bulk rename with patterns
-1, -2 suffix automatically.What is File Renamer?
Rename a batch of files with a template string plus optional find-and-replace. Tokens like `{name}`, `{ext}`, `{#}`, `{###}`, `{N}`, and `{date}` expand per file. Browsers can't rename files directly on disk — so the tool packages the renamed copies into a zip for download. Collisions in the zip get a `-1`, `-2` suffix automatically.
How do I use File Renamer?
- Drop files onto the upload zone.
- Edit the template (e.g. `{name}-{###}.{ext}`).
- Optionally set find/replace and case transformation.
- Download the renamed set as a zip.
When should I use File Renamer?
File Renamer is for batch renaming. To resize a batch of images at the same time, use Bulk Resize — it has the same zip-packaging flow plus per-image resizing.
What rename operations does it support?
Replace, prepend, append, number (padded counter), remove extension, change case, and regex replace — composable in any order.
Does it actually rename my files?
No — the browser cannot rename files on disk directly. The tool shows the new names and provides a copy-to-clipboard list plus a shell script (PowerShell and bash variants) you can run locally.
Can I preview before committing?
Yes. The preview table shows original → new for every file; mistakes are obvious before you run the script.
Is my file uploaded anywhere?
No. Everything runs in your browser. Your files never leave your device, and there is no server component for this tool.
