About FileNameTools

FileNameTools is a small, focused toolkit built around one workflow: generate consistent filenames, validate the ones you already have, and fix what's broken in bulk.

Inconsistent filenames cause real problems — broken links, silent overwrites, files that sort out of order, uploads rejected by a platform that doesn't like spaces or special characters. Most of these are avoidable with a naming pattern applied consistently, which is what these three tools are for.

Every tool runs entirely in your browser using standard Web APIs. Files you select are read, processed, and — for the Bulk Renamer — packaged into a ZIP for download, all on your device. Nothing is uploaded to a server.

FileNameTools is free to use and doesn't require an account. Naming conventions differ by platform and team, so the tools offer presets and options rather than enforcing one "correct" standard.
