Slug Generator

What is a Slug Generator?

A slug generator is an online tool that converts ordinary text — like an article title or product name — into a clean, URL-friendly string called a slug. A slug is the human-readable part of a web address that identifies a specific page, such as "how-to-bake-bread" in the URL example.com/blog/how-to-bake-bread.

Our Slug Generator instantly transforms any text into a properly formatted slug by converting it to lowercase, replacing spaces with separators, removing special characters and accents, and collapsing duplicate separators. Type or paste your text and copy the result in one click — no signup required.

Options Explained

Separator (Hyphen or Underscore)

Choose how words are joined in the slug. Hyphens (-) are the standard for web URLs because search engines treat them as word separators, making URLs more readable and SEO-friendly. Underscores (_) are commonly used for file names, database keys, and programming identifiers.

Lowercase

Converts every letter to lowercase. Lowercase slugs are strongly recommended for URLs because web servers can treat uppercase and lowercase paths as different addresses, which causes duplicate-content issues and broken links. Keeping slugs lowercase guarantees consistency.

Strip Special Characters

Removes punctuation, symbols, and other characters that are unsafe or ugly in URLs (such as ?, &, #, !, and quotes). Accented letters are also normalized to their plain ASCII equivalents (é becomes e, ü becomes u), producing a slug that works reliably across all browsers and systems.

Why URL Slugs Matter for SEO

A well-crafted slug improves both search engine optimization and user experience. Search engines use words in the URL as a ranking signal, so descriptive, keyword-rich slugs help pages rank for relevant queries. Clean URLs are also more likely to be clicked when they appear in search results, social media, and messages.

Short, readable slugs are easier to share, remember, and type than long URLs cluttered with query strings and random IDs. By keeping slugs lowercase, hyphen-separated, and free of stop words and special characters, you create links that look professional and stand the test of time.

What Makes a Good URL Slug

A strong slug is short, descriptive, and readable. The goal is for someone to glance at the URL and understand what the page is about before they even click it. That means including the words that matter — usually your main keyword or the core of your title — while trimming filler. A slug like 'best-running-shoes' communicates far more, to both people and search engines, than 'page-id-48217' or an overstuffed string of every word from the headline.

Removing stop words such as 'a', 'the', 'and', and 'of' keeps slugs concise without losing meaning, and using hyphens between words ensures search engines read them as separate terms. Keeping everything lowercase avoids the duplicate-URL problems that arise when servers treat different capitalizations as different pages. Stripping accents and special characters guarantees the link works reliably when shared, copied, or typed on any device.

It is also worth keeping slugs stable once a page is published. Changing a slug changes the URL, which can break existing links and lose accumulated search ranking unless you set up a redirect. Getting the slug right at the start — clean, keyword-focused, and timeless rather than tied to a date or a passing detail — pays off for the entire life of the page. This tool helps you produce exactly that kind of slug in one step.

Is the slug generator free?

Yes. It is completely free with no limits and no signup. You can generate as many slugs as you like, as often as you like, without ever creating an account.

Should I use hyphens or underscores in slugs?

For web URLs, hyphens are strongly recommended because search engines treat them as word separators, making the URL more readable and SEO-friendly. Underscores are better suited to file names, database keys, and programming identifiers.

Why should slugs be lowercase?

Web servers can treat uppercase and lowercase paths as different addresses, which leads to duplicate-content issues and broken links. Keeping slugs lowercase guarantees consistency and avoids these problems entirely.

Does it handle accented and special characters?

Yes. The generator converts accented letters to their plain ASCII equivalents (é becomes e, ü becomes u) and removes unsafe punctuation and symbols, producing a slug that works reliably across all browsers and systems.

How do I turn a blog title into a URL slug?

Paste your title into the box and the tool instantly produces a clean slug — lowercasing the text, replacing spaces with hyphens, removing accents, and stripping special characters. Copy the result and drop it straight into your CMS as the page's permalink.

Will changing a slug hurt my SEO?

It can. Changing a published slug changes the URL, which breaks existing links and can lose accumulated search ranking unless you set up a redirect. It is best to create a clean, keyword-focused slug from the start and keep it stable over time.

Does the slug generator work offline?

Yes. The slug is generated entirely in your browser as you type, so once the page has loaded it keeps working without an internet connection, and your titles and text are never uploaded to a server — which keeps unpublished posts and pages completely private.
