MobiDevices Slug Translate creates clean English slugs for post, page, and media URLs in multilingual WordPress sites. It can translate non-ASCII text, including Cyrillic, and supported Latin-language content into English before WordPress saves the slug.

Note: This plugin is no longer being actively developed, and we recommend switching to <a href="https://wordpress.org/plugins/cyrlitera/" rel="ugc">Cyrlitera</a>, a more advanced version with expanded features and customization options.
Transliteration is the process of converting characters from one writing system to another, such as converting Cyrillic symbols to Latin. Because most web software and URLs are designed around Latin characters, using Cyrillic or other non-Latin symbols in links or file names can lead to unreadable URLs, accessibility issues, and even broken links. Transliteration ensures your URLs and file names remain clean, readable, and compatible across all platforms.
This plugin automatically replaces Cyrillic, Georgian, Turkish, and other supported characters with Latin equivalents to create clean and readable URLs for posts, categories, taxonomies, products, and custom post types. It also fixes incorrect file names by removing unsafe characters and transliterating them during upload, helping prevent 404 errors and broken media links.
<h3>Examples</h3>
Cyrillic URL before transliteration:
<pre><code>https://example.com/%D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82-%D0%BC%D0%B8%D1%80
</code></pre>
Same URL transliterated to Latin:
<pre><code>https://example.com/privet-mir
</code></pre>
Incorrect file names before transliteration:
<pre><code>%D0%BC%D0%BE%D0%B5_image_290.jpg
A+nice+picture.png
</code></pre>
Readable transliterated file names:
<pre><code>moe_image_290.jpg
a-nice-picture.png
</code></pre>
By using Latin-based file names and URLs, you avoid issues with encoding, broken links, and unreadable paths. This plugin performs the transliteration automatically each time a file is uploaded, ensuring your media library stays clean and consistent.
