Type a file extension such as pdf, svg or woff2 and this tool returns the correct MIME type, also called the media type or Content-Type, that servers should send for that kind of file. You can also search by type, so entering a word like image or json filters the list to matching entries. Sending the right Content-Type matters because browsers and clients decide how to handle a response based on it, and a wrong or missing type can cause a file to download instead of display, or a script to be refused. This is a fast reference when configuring a web server, writing an upload handler, or setting response headers by hand. The extension to type mapping is built into the page, covering the common web, image, document, audio, video and archive formats, so it works offline with nothing sent anywhere.
Enter a file extension like .png or .json to get its correct Content-Type, or search by a media type to find matching extensions.
