Media Auto Hash Rename will rename any file (specific files can be ignored by file extension) during upload, with unique, low collision hashes. Hash characters and length can be configured for even lower collision rate.
More information please visit my <a href="https://sparanoid.com/work/media-auto-hash-rename/" rel="nofollow ugc">site</a>.
This plugin provides no configuration GUI to make it more easier to maintain with the future WordPress updates.
Currently there’re 3 constants you can configure in your <code>wp-config.php</code>, I recommend WP-CLI for maintaining these constants.
<ul>
<li><code>MAHR_LENGTH</code>: length of the random hashes, (default to <code>8</code>), longer can help reduce collision. Hashes at the length of 8 can be collision-free at the scale of 50,000 images).</li>
<li><code>MAHR_CHARS</code>: Characters used in hashes, default to <code>0123456789abcdefghijklmnopqrstuvwxyz_</code>, You can add more characters like uppercased alphabelts to dramatically reduce the collision without increasing the length of your filenames. But please note that this option can be dangerous if you’re not familer with general URI encoding. So if you don’t know what characters are allowed in a filename, just keep it untouched and use the default option.</li>
<li><code>MAHR_IGNORE</code>: File extensions to be ignored, default to <code>pdf, zip</code>, you can define a comma delimited list of file extensions to bypass renaming process of this plugin. All files that has the file extension you defined in the list will be ignored. Please note that:
<ul>
<li>File extensions must be defined without the leading peroid, for example: <code>'pdf, 7z, bmp'</code> works, <code>'.pdf, .7z, .bmp'</code> does not.</li>
<li>With (<code>'pdf, zip'</code>) or without (<code>'pdf,zip'</code>) space both work.</li>
<li>If you define your own ignore list, default ignore list will be discarded. For example, if you define <code>'7z'</code>, then <code>'pdf, zip'</code> will be processed during upload. You need to reapply these extensions with your own: <code>'7z, pdf, zip'</code>.</li>
<li>If you don’t need to ignore any files by its extension. define an empty array <code>[]</code> (without quotes) to this option: <code>define( 'MAR_IGNORE', [] );</code> to force process PDF and ZIP files.</li>
</ul>
</li>
</ul>

Goal of Seo File Names
<ul>
<li>
Seo File Names aims to save you time and boost your SEO by automatically renaming the files you upload to the media library with SEO friendly names.
</li>
<li>
This is often overlooked by website authors whereas search engines also rely on file names to understand and index them.
</li>
<li>
It also happens to me very often that clients ask me to upload many images and documents to their website. This plugin has saved me a lot of time by removing the automatic renaming software step (and license fees) before importing the files.
</li>
</ul>
How does Seo File Names works?
<ul>
<li>
When you upload a file to the media library, Seo File Names gathers datas from the post, page or term you are currently editing: title, slug, category, tag or taxonomy, type, dates, author…
</li>
<li>
…plus the global site datas: site name and site description, useful to reinforce your brand.
</li>
<li>
With this datas, you build the file names using the predefined tags.
</li>
<li>
You can insert arbitrary text between each tag.
</li>
<li>
The arbitrary text can only contain the characters [a-z], [0-9], space and ‘-‘.
</li>
<li>
Special characters, accented characters and capital letters will be filtered out.
</li>
<li>
Each part of the file name will be separated from the others by dashes if they are not.
</li>
</ul>
