Look up common media types by file extension, MIME type or description.
Check the input format and options with this example before using your own data. Random values, file sizes and presentation vary with the input and settings.
What to check in the result
image/pngMedia type reference
Find a MIME type for a file extension or HTTP header
Search for an extension such as png or a media type such as image/png. This is a reference lookup, not an inspection of uploaded file bytes.
PNG and JSON examples
A PNG image commonly uses image/png. JSON commonly uses application/json. Copy the media type matching the actual representation your server returns.
Content-Type and Accept differ
Content-Type describes the representation being sent. Accept expresses which response media types a client accepts. Looking up a type does not configure either header automatically.
An extension is not proof of file contents
Renaming a file to .png does not turn it into an image. Use the file type inspector for a header-based check; neither tool replaces malware analysis.
