SEO-Friendly URL Slug Generator

A URL slug generated by naively lowercasing a title and swapping spaces for hyphens tends to leave behind exactly the problems that matter, mangled accented characters, doubled-up separators, and stop words that add length without adding meaning. This tool converts a title, or a whole batch of them at once, into a clean slug that handles accented characters correctly, optionally strips common stop words, and enforces a sensible length limit by cutting at a word boundary rather than mid-word.

Why accented characters need real handling, not just deletion

A naive slug generator that simply strips anything that isn't a plain letter turns café into caf, résumé into rsum, and naïve into nave, silently deleting the accented letter entirely rather than converting it to something readable. This tool decomposes accented characters into their base letter and accent mark separately, then removes only the accent mark, so café correctly becomes cafe rather than losing a letter. It's a small detail that matters a lot for any title involving a name, a loanword, or non-English content.

Why hyphens and underscores aren't interchangeable

Google has specifically stated that hyphens are treated as word separators in a URL while underscores are not, which means best-seo-tools reads as three distinct words but best_seo_tools can be interpreted as one merged word instead. This is a real, specific reason to prefer hyphens rather than just a stylistic convention, and this tool defaults to hyphens for exactly that reason, showing an explicit note if underscore is selected instead so the tradeoff isn't hidden behind a neutral-looking dropdown option.

Batch conversion catches collisions before they happen

Converting titles one at a time makes it easy to miss when two different titles reduce to the exact same slug, "Best Tools (2026)" and "Best Tools 2026!" both strip down to identical text once punctuation is removed, and publishing both would mean two pages fighting over one URL. Pasting a whole batch of titles in at once surfaces this automatically, any slugs that collide are flagged directly in the results, which is far easier to catch here than after two pages have already been published to the same address.

Why stop word removal is a toggle, not automatic

Stripping words like "a," "the," and "of" shortens a slug and removes filler, but it isn't universally the right call, a title that's a specific, well-known phrase can lose meaning or readability without them. This tool defaults to removing them but makes it an explicit toggle rather than a fixed behavior, and includes a safety check for the edge case where a title is made up entirely of stop words, in which case the original words are kept rather than producing an empty slug.

Runs entirely in your browser

Every title is converted locally, nothing is uploaded or sent to a server. Once a page's slug is set, our Canonical Tag Checker and XML Sitemap Generator are natural next steps, both part of the same Technical SEO collection this tool belongs to.
