MIME Type Lookup
Type an extension (.webp) or a MIME type (image/webp) to look it up. Drop a file to see its real type from its content and whether the extension is wrong.
How to look up a MIME type
- Type an extension such as .webp or a MIME type such as image/webp into the search box; results appear as you type.
- Press the copy icon to paste the MIME type into your code or server settings.
- To find out what a file really is, drop it into the box below or paste it with Ctrl+V.
Frequently asked questions
It is the standard name of a kind of content, such as image/png for a PNG image or application/pdf for a PDF. Websites, email and APIs use it to know how to open a file instead of trusting the extension.

No. Only the start of the file is read to recognise the format, so a file of any size is checked at once.
The start of the file shows a different format than its extension, such as a PNG image named .jpg. Many upload forms reject such files; renaming it as suggested fixes that.
It recognises common formats: images, audio, video, PDF, archives, Word, Excel, PowerPoint, fonts, SVG and HTML. Plain text files (TXT, CSV, JSON) have no telltale start, so they are looked up by extension only.
It is completely free and needs no sign-up.
