Generate a slug
Turn a title, product name, or phrase into a clean, lowercase, URL-safe slug for blog posts, product pages, and file names. Choose a hyphen or underscore separator and an optional max length.
How to generate a slug
- Type or paste your title into the box.
- Choose a hyphen or underscore as the word separator (hyphens are the standard choice for URLs and SEO).
- Set a max length if your platform limits slug length, or leave it at 0 for no limit.
- Click Generate slug.
- Copy the result into your CMS, URL field, or file name.
This tool works best with plain English (ASCII) text. Accented letters and non-Latin scripts are stripped rather than transliterated, so check the result for text with accents or non-English characters.
What a slug is and how this generator builds one
A slug is the URL-friendly version of a title: lowercase, with spaces replaced by hyphens (or underscores) and punctuation removed, like "my-blog-post-title" instead of "My Blog Post Title!". This generator lowercases your text, strips characters that aren't letters, numbers, spaces, hyphens, or underscores, then collapses any run of spaces/hyphens/underscores into a single separator of your chosen type.
Best practices
- Use hyphens, not underscores, for web URLs. Search engines generally treat hyphens as word separators and underscores as joining characters, so hyphenated slugs are the standard SEO recommendation.
- Keep slugs reasonably short and descriptive. A slug like "10-tips-for-better-sleep" is more useful (and more clickable in search results) than a slug that includes an entire sentence.
- Set a max length if your CMS or platform has one, and check that the truncated slug doesn't end mid-word in a confusing way.
Common mistakes to avoid
- Using underscores for web content out of habit. Reserve underscores for contexts that specifically expect them, like some file-naming conventions; use hyphens for URLs.
- Assuming accented characters convert automatically. This generator strips characters outside plain ASCII letters and numbers rather than converting "café" to "cafe" — check the result manually for titles with accents.
- Changing a published slug without a redirect. If a slug is already live and indexed, changing it will break the old URL unless you set up a redirect.
Real-world use cases
- Blog post and article URLs generated from the post title.
- Product page URLs generated from the product name.
- File names that need to avoid spaces and special characters for compatibility.
- Anchor IDs and CSS/HTML identifiers derived from a heading or label.
Limitations
This generator does not transliterate accented or non-Latin characters (like turning "café" into "cafe" or converting Cyrillic or CJK text into Latin letters) — it strips characters outside the plain ASCII letter/number/separator set. For titles in other languages or with accents, review the output manually and adjust as needed before publishing.
Privacy
Text you enter is processed locally in your browser. It is not sent to a server, logged, or stored. See the privacy policy for the site's full data handling approach.
Troubleshooting
- If accented letters disappear from the result, that's expected — this tool strips rather than transliterates non-ASCII characters.
- If the slug is empty, your input likely contained only characters outside the supported set; try a title with plain letters and numbers.
- If the slug is cut off unexpectedly, check the max length field.
Conclusion
Use this tool to turn any title into a clean, URL-safe slug in one step. For converting the case of the underlying text separately, see the case converter.

FAQ
Should I use a hyphen or underscore?
Use a hyphen for web URLs. Search engines generally treat hyphens as word separators, which is the standard SEO recommendation. Underscores are better reserved for contexts that specifically expect them.
Does this handle accented letters or non-English text?
No. Accented and non-Latin characters are stripped, not converted. Review the output manually for titles that include them.
Will changing my slug break my existing page?
If the current slug is already published and indexed, changing it will change the URL. Set up a redirect from the old URL to the new one if the page is already live.
Is my text uploaded anywhere?
No. Slug generation happens locally in your browser and your text is not sent to a server.
