In-depth guide

MIME type lookup

Quickly map file extensions to MIME types and avoid incorrect content-type headers.

Why Content-Type matters

Browsers and APIs rely on MIME to parse payloads correctly and apply appropriate handling rules.

Operations use

Use this lookup when configuring static hosting, API gateways and download endpoints.

When to use it vs alternatives

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

Common pitfalls

Check the result before replacing the original input.
Watch for unit, format, encoding, and browser memory limits on large inputs.
Keep a copy of important source material until the output is verified.

Privacy and security

Browser-first by design. The tool page explains any exception before you use it.

Your input is handled in the browser wherever the tool can process it locally. EpitomeTool does not add an upload step unless a tool page explicitly says so.
