Slug Generator
ProductivityConvert titles or phrases into lowercase, hyphenated slugs suitable for URLs, filenames, or IDs — with control over separator and casing.
What a URL slug is
A slug is the human-readable part of a URL that identifies a specific page — in a URL like nonkera.com/guides/how-compound-interest-works, "how-compound-interest-works" is the slug. Slugs are conventionally lowercase, use hyphens instead of spaces, and strip out punctuation and special characters, since URLs need to avoid characters that have special meaning on the web (like spaces, question marks, or ampersands) or that require encoding to display correctly.
Why slugs matter for SEO
Search engines use the words in a URL as a mild ranking signal and, more importantly, display the URL in search results — a slug like /best-budget-laptops-2026 tells both Google and a human scanning results exactly what the page is about before they even click, while a slug like /post?id=48213 tells them nothing. Clean, descriptive slugs are also easier for people to read, remember, and share verbally or in a link, which is a real if less measurable benefit beyond pure search ranking.
How this generator works
Type or paste any text — a blog post title, a product name, a page heading — and the tool lowercases it, replaces spaces and most punctuation with your chosen separator (hyphens are the SEO convention, though underscores are supported too), and strips out characters that don't belong in a URL. The result updates as you type, so you can see exactly how a title will translate into a slug before you commit to it.
Slug best practices
Keep slugs reasonably short and focused on the core topic rather than mechanically repeating the full page title — a slug like /mortgage-calculator communicates just as much as /free-online-mortgage-calculator-tool-2026 while being cleaner and easier to share. Avoid stop words that add length without adding clarity ("a," "the," "of") when a shorter version reads just as well, and once a slug is published and indexed by search engines, avoid changing it without setting up a redirect — a changed URL without a redirect breaks existing links and search rankings built up over time.

Frequently asked questions
What characters are allowed in a slug?
Typically lowercase letters, numbers, and a separator (hyphens are the standard convention, though underscores are also supported) — everything else is stripped out.
Should I use hyphens or underscores in a slug?
Hyphens are the widely recommended convention — search engines treat a hyphen as a word separator, but historically haven't always treated an underscore the same way, so hyphens are the safer default for SEO.
Is my text sent anywhere when I generate a slug?
No — the conversion happens instantly in your browser using JavaScript, with nothing uploaded to a server.
Does it handle accented characters, like é or ñ?
Yes — accented characters are converted to their closest plain-letter equivalent (é becomes e, for example) so the slug stays URL-safe.
Can I use this for filenames, not just URLs?
Yes — the same clean, lowercase, separator-based format works well for filenames and IDs, not just URL slugs.
Is there a recommended maximum slug length?
There's no hard technical limit, but shorter, focused slugs (roughly 3-6 words) are generally easier to read, share, and rank well compared to long, keyword-stuffed ones.
