URL Slug Checker
100% PrivateURL & Link ToolsExamine one URL slug and fix everything that makes it messy, long or invalid.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Paste a slug on its own, or paste a whole URL and the checker reads the last path segment.
- 2Read the issue list: each problem is explained in plain language.
- 3Compare the cleaned slug shown below the verdict.
- 4Copy the cleaned slug with the Copy button and use it in your page, post or product URL.
Input: "My First Blog Post!" The checker reports three issues: uppercase letters, spaces, and a character that does not belong in a slug ("!"). Cleaned slug: my-first-blog-post
- Accented letters are transliterated where a standard equivalent exists (ü becomes u, ß becomes ss); characters with no Latin equivalent are removed.
- The checker follows common practice rather than one CMS's rules: a few platforms also allow underscores or uppercase, but lowercase hyphenated slugs work everywhere.
- Length guidance uses 75 characters as a practical ceiling, not a hard technical limit; very long URLs still work, they are just hard to share.
They work, but hyphens are the separator search engines document for readable URLs, and underscores are easy to miss when a link is underlined. The checker flags them as a quality issue, not an error.
About this tool
The URL Slug Checker examines one slug (or the last part of a full URL) and reports everything that makes slugs break or underperform: uppercase letters, spaces, underscores, stray symbols, doubled hyphens and excess length. It then produces a cleaned version you can copy straight into your CMS, so a post goes live with a tidy address the first time.
