Hyphens vs underscores
Search engines treat a hyphen as a word separator and an underscore as a word joiner, so hyphens are the safer default for readable, keyword-parseable URLs.
Stop words
Dropping "a", "the", "and" shortens a slug and sharpens its keywords. Keeping them can read better. It is a style choice, not a ranking factor — be consistent.
How long should a slug be?
Short enough to read and share — roughly 3–6 meaningful words. There is no exact length that helps or hurts rankings; the max-length option trims at a whole word.
How to generate slugs in JavaScript
The same logic this tool runs, as a small reusable function:
function slugify(input, { separator = '-' } = {}) {
return input
.normalize('NFKD') // split accented letters into base + mark
.replace(/[̀-ͯ]/g, '') // drop the combining marks
.toLowerCase()
.trim()
.replace(/[^a-z0-9]+/g, separator) // non-alphanumeric -> one separator
.replace(
new RegExp(`^\\${separator}+|\\${separator}+$`, 'g'),
'' // trim leading/trailing separators
);
}
slugify('10 Best React Tools for Developers!');
// -> "10-best-react-tools-for-developers"Transliteration here is limited to accented Latin letters via Unicode normalization. Scripts such as Cyrillic, Greek, Arabic or CJK are not romanised by this approach — use a dedicated transliteration library if you need that.
Frequently Asked Questions
What is a URL slug?
A slug is the human-readable part of a URL that identifies a specific page, usually derived from its title, such as "free-slug-generator" in sadevz.com/free-slug-generator/. Slugs use lowercase letters, numbers, and a separator instead of spaces or special characters.
Why should slugs be lowercase with hyphens?
Lowercase avoids duplicate-URL issues on case-sensitive servers, and hyphens are treated as word separators by search engines, which helps them parse individual keywords in the slug. Underscores are not treated as separators the same way, so hyphens are generally preferred for SEO.
Does this tool support accented or non-English characters?
Yes. Accented Latin characters such as é, ñ, or ü are converted to their closest plain-ASCII equivalent (e, n, u) before the slug is built, using Unicode normalization performed entirely in your browser.
What does removing common words do?
When enabled, small filler words like "a", "the", and "and" are stripped out before the slug is built, producing a shorter slug focused on the meaningful keywords in your title.
How long should a URL slug be?
Most SEO guidance recommends keeping slugs under roughly 50 to 60 characters so they display fully in search results and stay easy to read and share. The max length option truncates a slug at a whole word instead of cutting it mid-word.
Can I convert a whole list of titles at once?
Yes. Turn on bulk mode and put one title per line. Each line is converted to its own slug independently, in the same order, ready to paste into a spreadsheet or CMS.
Is my text sent to a server?
No. Every slug is generated locally in your browser using JavaScript. Nothing you type is transmitted, logged, or stored anywhere.
Should a URL slug use hyphens or underscores?
Hyphens. Search engines treat a hyphen as a word separator and an underscore as a word joiner, so "react-tools" reads as two words while "react_tools" can read as one. Hyphens are also the long-standing convention for readable URLs. This tool defaults to hyphens; underscore is available if a system you target requires it.
Should URL slugs contain stop words like "the" and "and"?
It is optional. Removing stop words makes a slug shorter and keyword-focused; keeping them can read more naturally. Neither choice meaningfully changes rankings on its own — pick one and stay consistent. The "Remove common words" option does either.
How do I generate a URL slug in JavaScript?
Normalise accents with normalize('NFKD') and strip the combining marks, lowercase, replace every run of non-alphanumeric characters with one hyphen, then trim leading and trailing hyphens. See the copy-ready function in the JavaScript section above.
