About this tool

Decoders and inspectors crack open an encoded or packed value — a JWT, a data URI, a Unix timestamp, a URL, a user-agent string — and show you the human-readable pieces inside without you eyeballing base64 by hand.

How to use it

  1. Paste your input

    Drop your text, code, or data into the input box. MIME Type Lookup runs on whatever you enter — no sign-up and no size limit beyond what your browser can hold.

  2. Read the result instantly

    The output updates as you type, computed on your device. A valid / invalid badge tells you at a glance whether the input parsed.

  3. Copy it

    Press Copy to put the result on your clipboard, ready to paste into your editor, terminal, or ticket.

Frequently asked

Is my data uploaded to a server?
No. MIME Type Lookup runs 100% in your browser tab, so whatever you paste never leaves your device — safe for tokens, configs, and private payloads.
Does it work offline?
Yes. Once the page has loaded it keeps working with no network, because all processing happens locally.
Is there a size limit?
No hard limit. It handles as much as your browser can hold in memory, and it all runs on-device.
