Clean Image Filenames

Description

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.

Features

  • Converts accent characters to non-accent, latin equivalents in Swedish, Danish, German, and more.
  • Removes special characters like exclamation marks, periods, hashtags, and more.
  • Lets you choose if you want to convert only image files, or all file types.
  • Makes site and server migrations easier thanks to non-accent character filenames.
  • Provides filter hook for developers who want to specify which file types to convert.

Examples

  • Räksmörgås.jpg raksmorgas.jpg
  • Æblegrød_FTW!.gif aeblegrod-ftw.gif
  • Château de Ferrières.png chateau-de-ferrieres.png

Worth noting

The plugin only converts filenames when the files are being uploaded. It can not convert existing files.

Filter for developers

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 Wikipedia.

The following example will convert PDF, JPEG and PNG files only:

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' );

Screenshots

  • Easily choose between cleaning the filenames of all file types or images only.

I recommend this. When there is diacritics in the file name, this simply substitutes that for a letter without diacritics. Works very well!

Saves my life every day, German words just have to many Äs, Ös & Üs 😉

In Denmark, we use the letters æ, ø, and å, which by danish standards, are translated into ae, oe and aa when necessary. Many plugins similar to Clean Image Filenames, fails to do that properly. That’s no catastrophe, its only media filenames after all, but you might as well get it right if possible. Futhermore, titles are left alone – that’s a big plus. So the title of a file called “Æblegrød.jpg” stays that way, while the filename get converted to “aeblegroed.jpg”, just as I need it. Lastly, this plugin, seems to be the only one of its kind, that has been tested with WordPress 5.1 – the others, while still working, seems abandoned. So – a big 5-star thank you from me. Bjarne
