Making the image filenames for your WordPress website clean is very important. The search engines will use these clean file names to help users find your images and ultimately your website. Along with the search engines using the names, when you use names that have uncommon characters, they may not be read properly in the browser.

Whether you're the only one uploading images or you've allowed other users to do so, too, using clean images makes a difference. Here's a quick and easy way to ensure all your image names remain clean.
<h2>Using the Clean Image Filenames Plugin for WordPress</h2>
The <a href="https://wordpress.org/plugins/clean-image-filenames/">Clean Image Filenames Plugin for WordPress</a> will allow you to use great file names and avoid using bad ones. Download the plugin, install it and activate it to continue with this step-by-step approach to eliminating bad image filenames.

Once this plugin has been installed, you won't have to worry about your image filenames any more. However, it's important to note, the plugin won't fix past images you have used just because you installed it. You will either have to go back and redo all of those images or you will have to change those manually.

Moving forward, when you upload an image with a name that isn't considered a clean filename, the plugin will automatically filter out the bad characters. You won't have to adjust any setting or do anything other than just install the plugin.
<h2>More than Just Images</h2>
Not only will the Clean Image Filenames plugin work for images, but it will also work for other file types. It won't alter your database or any upload settings and its multisite compatible.

By default, the plugin will filter .GIF, .PNG and .JPEG files. However, if you make a few changes to the clean_image_filenames_mime_types filter, you can make this plugin work with just about any type of file uploaded. Here's an example of what the cost might look like for another file.

This code would allow the plugin to work with .PDF files, as well as the default file types.

If you want to make sure all of your image filenames are clean, use this plugin. No longer will you have to worry about search engines not finding and indexing your images and you won't have to worry about the images breaking in some browsers either.
