Frequently asked questions
Is MIME Type Lookup free to use?

Does MIME Type Lookup upload my files?
No. MIME Type Lookup processes everything locally in your browser. Toolncy never receives the files you open for mime lookup.
Is MIME Type Lookup safe for confidential work?
Yes for architecture: nothing is uploaded. Still use a trusted device — local malware can read browser memory like any app.
Does MIME Type Lookup work on phones?

Does MIME Type Lookup send code to a server?
No. mime lookup transforms run in your tab. Safe for tokens and snippets you would not paste into a cloud formatter.
