Om det här verktyget
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.
Useful for tidying up phone photo dumps, prepping a dataset of files for processing, batch-renaming downloaded podcasts, or making messy filenames consistent before importing into a CMS. Runs in your browser.

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