About this tool
A MIME type tells a browser or server what kind of data a file holds, such as text, an image or a video, so it can handle it correctly. This tool takes an extension or a full filename, strips the name down to the extension, and returns the matching type from a built-in table of common types. Unknown extensions are reported honestly rather than given a made-up type.
Frequently asked questions
What happens with an unknown extension?
The tool says the extension is not in its table, because guessing a type for an unfamiliar extension could cause a file to be handled wrongly.
Does the filename itself affect the result?
No. Only the part after the last dot is used, so photo.png and report.png give the same answer.
