Slugify: Make a Clean URL Slug

A good slug is short, lowercase and readable, with hyphens between words and no spaces, accents or symbols. That keeps links tidy, easy to share, and simple for both search engines and people to parse at a glance.

Text is normalised so accented Latin letters lose their marks, turning 'é' into 'e' and 'ñ' into 'n'. Characters with no plain a to z or 0 to 9 equivalent, such as many non-Latin scripts, are treated as separators and dropped to keep the slug URL-safe.

Search engines have long treated hyphens as word breaks and underscores as joiners, so hyphens are the safer default for indexable URLs. The tool still offers an underscore option for systems, filenames or frameworks that expect one.

It caps the slug at the number of characters you set, then trims back to the last complete word so nothing is cut mid-word and no trailing separator is left. For example, capping 'The Quick Brown Fox' at 13 yields 'the-quick' rather than 'the-quick-bro'.

Yes. Untick the Lowercase box and the original casing is preserved, so 'Blog Post Title' becomes 'Blog-Post-Title'. Most URLs are lowercased by convention, but mixed case is available when a system requires it.

Digits 0 through 9 are kept as-is, so version numbers and years survive. Existing hyphens, spaces and punctuation all collapse into a single separator, meaning a double space or a stray dash never produces an empty gap in the slug.

Yes. A title that starts or ends with punctuation, like 'Hello, World!', never leaves a dangling separator. Runs at the very start and end are stripped so the slug always begins and ends with a real character.

There is no hard cap unless you set one with Max length. The slug updates instantly as you type, and the character counter next to the field helps you keep it within whatever limit your CMS or platform prefers.

Yes. The slug is generated entirely in your browser with JavaScript, and nothing you type is uploaded, so unpublished titles and drafts stay on your device.
