Why are hyphens preferred over underscores for URL slugs?

Major search engine crawlers treat hyphens as space delimiters between words, whereas underscores are treated as joining characters.

Does the slug generator support non-Latin alphabets?

The tool converts accented Latin letters to ASCII. For non-Latin scripts (Cyrillic, Arabic), it strips unsupported symbols or preserves encoded paths.

Is any title data transmitted over the internet?

No. All regex transformations, normalization, and string replacements run client-side in your browser.

Options explained

Hyphen Separator (-)

Separates words with standard hyphens, recommended by Google Search for URL readability.

When to use: Use for blog post permalinks, documentation routes, and e-commerce product pages.

Unicode Transliteration

Normalizes accented characters (é → e, ö → o, ñ → n) using Unicode NFD decomposition.

When to use: Essential for international titles so URLs remain clean ASCII without percent-encoding.

Stop Words Filter

Optionally strips minor words like 'the', 'a', 'and', 'in' for shorter, punchy URLs.

When to use: Use when creating concise permalinks for high-ranking marketing articles.

Worked example

Input: '10 Tips for Café & Crème Brûlée Lovers!'

Output: '10-tips-for-cafe-and-creme-brulee-lovers'

Processed using Unicode canonical decomposition and regex symbol sanitation.

Tips & limits

Search engines treat hyphens as word separators; avoid underscores for public web permalinks.
Keeping slugs under 50 characters makes URLs cleaner to share on social platforms and mobile screens.
Removing special characters avoids percent-encoding (like %20 or %C3%A9) in browser address bars.

Common problems

Accented letters disappeared rather than converting to ASCII: The engine uses NFD normalization to strip combining diacritical marks while preserving base Latin letters.
Output contains double hyphens: The tool automatically collapses multiple consecutive spaces and punctuation marks into single hyphens.
