What the author says it does

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:

Questions the author answers

Where this page's numbers come from

Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin. The author takes donations at their donate page.
