Safe Filename

Safe Filename

Clean document filenames before submitting strict upload forms. Replace spaces, symbols, and non-ASCII characters with a simple lowercase name while keeping the selected file contents unchanged.

When to use it

  • An upload form rejects filenames with spaces or symbols.
  • A document name includes non-English characters that a portal does not accept.
  • You want a simple lowercase filename before submitting an application.
  • You need a renamed download without changing the original file contents.

How it works

Choose a file, review the suggested safe name, edit it if needed, and download a copy with that name. The current MVP uses browser Blob URLs for the local download and does not send the selected file to a server.

Privacy principles

  • No upload.
  • No account is required.
  • No cloud storage is used.
  • No file history is kept by the app.
  • The selected file contents are not modified.
  • The renamed copy downloads locally from your browser.
