MIME Type Lookup
About MIME Type Lookup
Look up a MIME content type by filename or extension, or find extensions for a MIME type. Check common mappings without uploading or inspecting file contents.
How to use this tool
Enter a filename, extension, or MIME type to look up the corresponding content type or known extensions.
What to know
An extension lookup does not inspect file bytes. Validate actual content before trusting an uploaded file type.
