File Name Cleaner

Clean messy file names by removing special characters, normalizing case, and applying a consistent separator.

About this tool

Standardize file names before uploads, shared folders, or content handoff so your assets stay readable and consistent.

File Name Cleaner is useful when messy asset names need to become more consistent before upload, sharing, or migration. It helps normalize punctuation, separators, and casing so files are easier to manage across shared folders, CMS imports, and handoff workflows.

  • Cleans file names by lowercasing text and removing messy punctuation.
  • Lets you choose between hyphens, underscores, or spaces as the separator.
  • Preserves file extensions while normalizing them to lowercase.

How to use File Name Cleaner

Paste one or more file names, review the cleaned output, and then reuse the normalized names in your upload list or rename plan. If multiple teams contribute files, test a mixed sample first so you can confirm the chosen separator and casing rules fit the broader naming convention.

    Frequently asked questions

    Can I clean multiple file names at once?

    Yes. Paste one file name per line and the tool will normalize them all at once.

    Does it keep the extension?

    Yes. You can keep the extension and it will be normalized to lowercase.

    Which special characters are removed by default?

    Characters that are unsafe for URLs and cross-platform file systems are removed, including @, #, %, &, and curly braces, while hyphens, underscores, and dots are preserved.

    Does the cleaner handle Unicode characters like accented letters or CJK text?

    Accented Latin characters are transliterated to their ASCII equivalents by default. CJK and other non-Latin characters are preserved unless you enable the ASCII-only mode.

    Can I choose between hyphens and underscores as the separator?

    Yes, you can select hyphens, underscores, or dots as the consistent separator, and the tool replaces all spaces and existing mixed separators with your chosen character.
