MIME Types Cheatsheet - Content-Type Reference
A wrong Content-Type is often the invisible cause of broken downloads, garbled pages and rejected uploads. Organized by file category, each media type maps to extensions, the correct Content-Type string and charset notes. Use it to configure Nginx mime.types, set response Content-Type in server code, and validate what a browser infers from the header. After reading you know why .wasm or .woff2 serves wrong and how to fix it.

Tips
- Nginx MIME types live in /etc/nginx/mime.types.
- For file uploads set Content-Type to multipart/form-data; the browser handles boundaries.
- JSON API responses should set Content-Type to application/json; charset=utf-8.
- octet-stream triggers a browser download — use for unknown or forced-download types.
