Slugs read better than numeric IDs and survive title rewrites better than the original prose. "product-name-blue-large" beats "123" in a URL by every measure: it's memorable, it carries keywords for search engines, and it tells visitors what the page is about before they click.

What characters are allowed?

Lowercase letters a–z, digits 0–9, and hyphens are the safe set. Some systems also accept underscores, though that's less standard. Special characters, punctuation, and accented letters get either stripped or transliterated, and runs of whitespace collapse into single hyphens.

Should I use hyphens or underscores?

Hyphens. Google has long stated that it treats hyphens as word separators while underscores are sometimes treated as joiners. The SEO difference is small but real, and hyphens have become the strong convention across modern CMS platforms.

What about non-English characters?

Two reasonable strategies. The first transliterates accented characters (café → cafe), which produces ASCII-only slugs that work in every system. The second preserves the original Unicode and relies on percent-encoding when the URL is transmitted. Pick whichever fits your audience and tooling.

Should I remove stop words?

It's a judgment call. Removing words like "a," "the," and "of" trims length and slightly bumps keyword density. Keeping them often produces a more natural-sounding URL. Most teams strip the worst offenders and keep stop words that affect clarity.

Can I change a slug after publishing?

You can, but always pair the change with a 301 redirect from the old URL. Backlinks, search engines, and social shares all reference the original, and a silent rename produces 404s and lost rankings. Avoid renaming purely for stylistic reasons.

Is the data sent anywhere?

No. The transformation is pure string manipulation running locally in your browser. The titles you enter stay on your device.

How to Use Slug Generator

Enter your title

Type or paste the title, headline, or any string you want converted into a slug. The tool processes it as you type.

Adjust the rules

Pick whether to lowercase the result, choose hyphens or underscores as the separator, decide how to handle accented characters, and set a maximum length if you want short URLs.

Review the slug

The generated slug appears below the input — lowercase, hyphenated, and stripped of any characters that would need URL encoding.

Use it where it belongs

Drop the slug into a blog post URL, a product page route, a category path, or a filename. Once it's published, leave it alone — changing slugs without a 301 redirect is one of the easiest ways to lose traffic.

When to Use Slug Generator

Turning article titles into URLs

A slug is the URL-friendly version of a title. "My First Blog Post!" becomes my-first-blog-post once the punctuation is dropped, the spaces collapse to hyphens, and the casing flattens. The result is a readable, stable URL that survives title rewrites without breaking inbound links — exactly what every blog and CMS needs.

Naming files predictably

Slugs aren't only for URLs. Generating consistent filenames from descriptive titles makes asset libraries searchable and keeps photos, documents, and exports sorting cleanly. Anything from event-photo-2024-summer-festival.jpg to proposal-acme-redesign-draft-v1.pdf reads better than a numeric dump.

Generating identifiers and keys

Slugs work well as human-readable primary keys in tagging systems, category routes, and content-addressed APIs. Compared to integer IDs, they're easier to read in URLs and dramatically easier to debug when you spot one in a log or query string.

Handling non-ASCII characters

International titles need a strategy. You can transliterate so café becomes cafe, preserve the Unicode and rely on browser percent-encoding, or strip the unsupported characters entirely. The right choice depends on your audience and the systems consuming the slugs downstream.

The transformation is the standard one almost every CMS implements. Lowercase the letters, replace whitespace with hyphens, drop the trailing punctuation, and preserve numbers and ASCII letters. The exclamation point disappears, the rest of the words stay.

Title with diacritics and odd punctuation

Input

Café & Restaurant — A Review

Output

cafe-and-restaurant-a-review

Accented characters typically transliterate to their closest ASCII counterparts (café becomes cafe). The em dash goes away, and the ampersand can either be replaced with the word "and" or stripped entirely depending on configuration.

A title that's too long

Input

An Extremely Long Article Title That Goes On And On And On

Output

an-extremely-long-article-title-that-goes-on-and-on-and-on, or truncated to an-extremely-long-article-title

Most slug generators offer a maximum length so the result stays under roughly 50 to 60 characters. Shorter slugs are friendlier in social shares and easier to remember, so cutting off marginal words usually pays off.

Tips & Best Practices for Slug Generator

1.Always lowercase the result. Most servers treat URLs as case-insensitive, but mixed casing creates the kind of subtle duplicate URLs that confuse analytics and split link equity.
2.Use hyphens, not underscores. Google explicitly treats hyphens as word separators while it doesn't always parse underscores the same way, so the choice has a small but real SEO consequence.
3.Don't change slugs after publishing without a 301 redirect. Backlinks, bookmarks, and social shares all reference the old URL, and silent renaming is one of the easiest ways to lose traffic you already earned.
4.Stripping stop words like "the," "a," and "of" is a stylistic choice. The savings are real but small; do whatever produces the most readable result for your readers.
5.Aim for three to five meaningful words. Long slugs feel awkward to share and lose impact in search snippets where only part of the URL is visible.
6.Front-load the primary keyword. "best-running-shoes" is more useful than "top-pick-2024" because the slug echoes what readers actually search for.

Frequently Asked Questions

A slug is the URL-friendly version of a string, usually a page title. It's lowercase, uses hyphens instead of spaces, and contains only ASCII letters, numbers, and hyphens. "My First Post!" becomes my-first-post — readable, stable, and SEO-friendly. The convention took hold during the early blogging era of the 2000s.
