Will Sitecore support Jpeg 2000 , Jpeg XR, webp image format by default?

Question

We have recommendation from our seo team to use image format like jpeg 2000, jpeg XR, webp but when we try to upload Jpeg 2000 image with extension .jp2, sitecore not taking as image format instead it takes as file. Are we missing any configuration to support these image format?

welcome to SSE.

For Sitecore to recognize a .jp2 extension, you would need to set that up in the configuration of the media types.

Out of the box, the jpeg configuration is like this:

<mediaType name="JPEG image" extensions="jpg, jpeg, jpe, jfif">
    <mimeType>image/jpeg</mimeType>
    <forceDownload>false</forceDownload>
    <sharedTemplate>system/media/unversioned/jpeg</sharedTemplate>
    <versionedTemplate>system/media/versioned/jpeg</versionedTemplate>
    <mediaValidator type="Sitecore.Resources.Media.ImageValidator"/>
    <thumbnails>
        <generator type="Sitecore.Resources.Media.ImageThumbnailGenerator, Sitecore.Kernel">
            <extension>png</extension>
        </generator>
        <width>150</width>
        <height>150</height>
        <backgroundColor>#FFFFFF</backgroundColor>
    </thumbnails>
    <prototypes>
        <media type="Sitecore.Resources.Media.JpegMedia, Sitecore.Kernel"/>
    </prototypes>
</mediaType>

Notice that in the extentions attribute, jp2 is missing. You could either patch that to add jp2 or just add a new mediaType with the jp2 extension like this:

<mediaType name="JPEG image" extensions="jp2">
    <mimeType>image/jpeg</mimeType>
    <forceDownload>false</forceDownload>
    <sharedTemplate>system/media/unversioned/jpeg</sharedTemplate>
    <versionedTemplate>system/media/versioned/jpeg</versionedTemplate>
    <mediaValidator type="Sitecore.Resources.Media.ImageValidator"/>
    <thumbnails>
        <generator type="Sitecore.Resources.Media.ImageThumbnailGenerator, Sitecore.Kernel">
            <extension>png</extension>
        </generator>
        <width>150</width>
        <height>150</height>
        <backgroundColor>#FFFFFF</backgroundColor>
    </thumbnails>
    <prototypes>
        <media type="Sitecore.Resources.Media.JpegMedia, Sitecore.Kernel"/>
    </prototypes>
</mediaType>

Depending on your IIS settings you may also need to add a mime type in your web.config like this:

<configuration>
    <system.webServer>
        <staticContent>
            <remove fileExtension=".jp2" />
            <mimeMap fileExtension=".jp2" mimeType="image/jp2"/>
        </staticContent>
    </system.webServer>
</configuration>
