MIME Type Lookup by File Extension
Check common content types for file extensions, asset URLs, and deployment notes. Useful for headers, uploads, static assets, docs, and CDN QA.

MIME lookup uses a practical extension table. Confirm final Content-Type behavior in your server, CDN, storage bucket, or upload pipeline.
Asset filenames
Use names like app.js, image.webp, font.woff2, or data.json.
Extension lists
Paste comma-separated extensions from QA docs or upload requirements.
Example
photo.webp maps to image/webp and data.json maps to application/json.
Assumption
The extension is the signal you want to use for the lookup.
Limitation
The tool does not inspect binary file contents or verify an actual server Content-Type header.
Can I paste URLs?
Yes. The tool reads the extension before query strings or fragments.
Does it cover every extension?
No. It covers common web, image, font, document, audio, video, and archive types.
Can servers send a different type?
Yes. Always check the live response header when deployment accuracy matters.
How is the text input processed?
Processing is handled in the browser for this tool based on the current public implementation.
Suggested workflow
Asset QA path
Check file type expectations, then validate related image and checksum details.
