<p>This plugin automatically converts language accent characters in filenames when uploading to the media library. Characters are converted into browser and server friendly, non-accent characters.</p>
<h3>Features</h3>
<ul>
<li>Converts accent characters to non-accent, latin equivalents in Swedish, Danish, German, and more.</li>
<li>Removes special characters like exclamation marks, periods, hashtags, and more.</li>
<li>Lets you choose if you want to convert only image files, or all file types.</li>
<li>Makes site and server migrations easier thanks to non-accent character filenames.</li>
<li>Provides filter hook for developers who want to specify which file types to convert.</li>
</ul>
<h3>Examples</h3>
<ul>
<li>Räksmörgås.jpg <span aria-hidden="true" class="wp-exclude-emoji">→</span> raksmorgas.jpg</li>
<li>Æblegrød_FTW!.gif <span aria-hidden="true" class="wp-exclude-emoji">→</span> aeblegrod-ftw.gif</li>
<li>Château de Ferrières.png <span aria-hidden="true" class="wp-exclude-emoji">→</span> chateau-de-ferrieres.png</li>
</ul>
<h3>Worth noting</h3>
<p>The plugin only converts filenames when the files are being uploaded. It can not convert existing files.</p>
<h3>Filter for developers</h3>
<p>This filter provides developers a way to specify which file types the plugin should convert. This filter overrides the plugin settings on the media settings page. For a complete list of mime types, see <a href="http://en.wikipedia.org/wiki/Internet_media_type" rel="nofollow ugc">Wikipedia</a>.</p>
<p>The following example will convert PDF, JPEG and PNG files only:</p>
<pre><code>function my_clean_image_filenames_mime_types() {
    $mime_types = array(
        'application/pdf',
        'image/jpeg',
        'image/png',
    );
    return $mime_types;
}
add_filter( 'clean_image_filenames_mime_types', 'my_clean_image_filenames_mime_types' );
</code></pre>
