Clean Image Filenames is a WordPress plugin designed to enhance file uploads by automatically converting language accent characters in filenames to their non-accented Latin equivalents. This functionality is particularly beneficial for users uploading files in languages such as Swedish, Danish, and German. Additionally, the plugin removes special characters like exclamation marks and hashtags, ensuring that filenames are browser and server-friendly. Users can choose to apply these conversions to image files only or to all file types, making it a flexible tool for various multimedia needs.

One notable advantage of Clean Image Filenames is its ability to simplify site and server migrations by standardizing filenames. However, it is important to note that the plugin only processes filenames during the upload phase and does not alter existing files. For developers, a filter hook is provided, allowing customization of the file types to be converted, which enhances its utility for specific use cases.
