Text to Slug: generate URL-ready slugs instantly

A slug is the readable, URL-safe part of a web address that identifies a specific page — the part after the domain, like "textstool.com/text-to-slug". It's lowercase, uses hyphens instead of spaces, and strips out punctuation and special characters, so it stays clean no matter what platform renders it.

Why slugs matter for URLs

A good slug is short, readable, and descriptive — search engines and readers can both tell what a page is about just from the URL. A messy URL full of spaces, capital letters, or special characters gets encoded into ugly sequences like "%20", looks unprofessional when shared, and is harder to type or remember. Most content management systems and static site generators expect a slug-formatted path for every page or post.

How our slug generator works

Paste in a title, heading, or sentence, and the slug updates as you type — no button to click. The converter lowercases everything, strips accents down to their closest plain letter (é becomes e, ñ becomes n), removes punctuation, and replaces runs of spaces or existing separators with a single hyphen or underscore, depending on which you choose. Leading and trailing separators are trimmed automatically.

Hyphens vs. underscores

Hyphens are the standard for public-facing URLs — search engines treat a hyphen as a word separator, but generally don't treat an underscore the same way, so hyphenated slugs tend to be more SEO-friendly. Underscores still show up in file names, code identifiers, and some internal systems where that convention is already established, which is why both options are available here.
