Common questions

Case Converter FAQ

Does the converter preserve acronyms?

Recognized acronyms such as API, BBQ, HTML, NASA, and SQL keep their established uppercase spelling.

Is submitted text stored?

No. Conversion runs locally in the current browser tab, and Tool Packer does not receive or store the text.

Are editorial profiles guaranteed to match every publisher rule?

No. The profiles cover deterministic, documented differences but do not replace a publisher's complete style manual or human review.
