Find the MIME type of a common extension

Developers and content teams use it to select the MIME type for a file extension before an upload or HTTP response.

Find the MIME type of a common extension. Everything runs in your browser, so the values you enter are never uploaded, shared, or stored.

How to use

Enter the extension you are looking for, such as .webp, in the provided field.
Run the identification to search the reference table.
Read the MIME type shown for that extension.
If needed, clear the field to test another extension.

Example

In the sample, the extension .webp is submitted to the tool. Look at the MIME type it returns and compare it with what your configuration expects; this helps prepare a header or a file upload.

Input

.webp

Output

.webp: image/webp

Limits and formats

The table covers common extensions, not every existing format.
One extension can map to different MIME types depending on context or server settings.
The exact MIME type may depend on the configuration of the site publishing the file.
Check the result before using it in an HTTP response or upload.

Where processing happens

The lookup runs in your browser. The extension you enter stays on your device, no account is required, and nothing is stored after the search.

Frequently asked questions

What is a MIME type?

A MIME type is a label that describes the nature of a file, such as image, text or video. Browsers and servers use it to decide how content should be handled or displayed.

Can I enter an extension without a dot?

The field expects an extension such as .webp. Depending on the accepted format, you can try with or without the dot, but the provided example uses the dot form. If no answer appears, check the spelling.

Is the MIME type always the one my site uses?

Not always. A site can map an extension to another MIME type through its configuration. Use the result as a reference, then confirm it with your hosting provider or in your response headers.
