URL Slug Generator

URL Slug Generator: Turn Any Title Into a Clean, SEO-Friendly Slug, Free in Your Browser

A URL slug is the part of a web address that comes after the domain and identifies one specific page, for example the url-slug-generator in smallstudytools.com/url-slug-generator/. Search engines and readers both use it: Google treats a descriptive slug as a small but real on-page relevance signal, and a human scanning a search result or a shared link can often tell what a page is about from the slug alone. The usual problem is that real titles are messy. They contain capital letters, punctuation, apostrophes, numbers, and sometimes emoji, none of which belong in a clean URL. This tool handles that conversion for you, instantly and for free.

Everything runs as plain JavaScript string processing in your own browser tab. There is no AI model guessing at your slug and no server involved: the same deterministic rules run every time, so the same title always produces the same slug.

1What Counts as a Good URL Slug

A well-formed slug is lowercase, uses a single consistent separator between words, and contains only letters, numbers, and that separator, nothing else. Accented characters are converted to their plain-letter equivalents, apostrophes are dropped rather than turned into stray hyphens, and runs of punctuation collapse into a single separator instead of leaving double hyphens behind. This tool applies all of those rules automatically, so a title like "What's the Best Study Routine? (2026 Guide)" becomes a slug such as whats-the-best-study-routine-2026-guide, with nothing left over to clean up by hand.

2Choosing a Separator: Hyphens, Underscores, or None

Simple Mode always uses a hyphen, which matches Google's own long-standing recommendation and is the default separator on WordPress, Shopify, and most other platforms. Pro Mode adds two alternatives for the cases where a project needs something different: an underscore separator for systems that specifically expect it, and a no-separator camelCase style (for example myTitleHere) for identifiers that are not meant to be a public-facing web URL at all, such as an internal key or filename. Whichever style is chosen applies consistently across both the single-title box and bulk conversion.

3Simple vs Pro

Simple Mode covers the everyday case: one title in, one clean slug out. Pro Mode, currently free to use, is built for the moment a whole batch of pages needs slugs at once, such as migrating a blog, bulk-importing products, or restructuring a site's URLs in one pass.

4Who Uses a URL Slug Generator

None of these need an account, a subscription, or a download, just a title and a couple of seconds. That is the gap this tool fills: a fast, honest slug generator instead of a heavier CMS plugin or a paid API-backed service built for a different job.

5Bulk Conversion and Keeping Every Slug Unique

Pro Mode's bulk conversion is built for the moment a single title is not the problem, a whole list is. Paste titles in, one per line, click Convert All, and every row is processed with the same separator, stop-word, and length settings in one pass, shown in a title → slug results table. Two different titles sometimes reduce to the exact same slug once punctuation is stripped and the text is lowercased; when that happens the tool automatically appends -2, -3, and so on so every row stays unique, and flags which rows were auto-incremented so nothing gets silently renamed without your knowledge. The whole batch can be copied at once or downloaded as a CSV file to hand to a content team or import into a spreadsheet.
