Über dieses Tool

Bulk-rename files with a prefix, suffix and find/replace pattern (with optional regex). The renamed copies download as a single ZIP - your originals on disk are never touched.

Häufig gestellte Fragen

Are my original files modified?

No - your originals on disk are untouched. The download is a ZIP of renamed copies. Delete the originals manually if you want to fully replace them.

Can I add a sequential number?

Yes - use {n} in your prefix or suffix as a placeholder for an incrementing number. Padding (e.g. {n:3} for 001, 002, 003) is on the roadmap.

Will the ZIP preserve folder structure?

Currently the ZIP is flat - all files at the root. Folder-aware bulk rename is on the roadmap.

How does regex find/replace work?

Standard JavaScript regex - useful for stripping common prefixes (^IMG_), reformatting numbers, or other pattern-based renames. Capture groups can be referenced as $1, $2 in the replacement.

Can I undo a rename?

The tool runs entirely in your browser and only generates renamed copies for download - the originals on your disk are never modified. If you don't like the result, just discard the downloads.

Does it preserve file creation dates?

Browsers can't set arbitrary timestamps on downloaded files - they get the current date and time when written to disk. If preserving original timestamps matters, use a desktop tool instead.
