Is URL Slug Generator free to use?

Yes. URL Slug Generator is free, has no usage cap and does not require an account. There is no paid tier that unlocks extra output.

Does my data get uploaded to a server?

No. The tool is a JavaScript function that runs inside your browser tab. Nothing you paste or drop in is transmitted, logged or stored by us.

Do I need to create an account?

No account, no email address and no sign-in. Open the page and start working.

Does it work on a phone or tablet?

Yes. The interface is responsive and works in mobile Chrome, Safari, Edge, Firefox and Samsung Internet. You can also install Toolspea as an app from the browser menu.

Can I use the output commercially?

Yes. You keep every right you already had over the input, and we claim nothing over the output.

Should a slug use hyphens or underscores?

Hyphens. Search engines treat a hyphen as a word separator and an underscore as a joiner, so file_name reads as one token while file-name reads as two.

How long should a URL slug be?

There is no hard rule, but three to six meaningful words is a practical target. Shorter slugs are easier to share, cite and display in search results without truncation.

Should I remove stop words?

Only when the slug stays readable. 'How to fix a slow site' shortened to fix-slow-site is fine; removing 'the' from 'the-hague' is not.

What happens if I change a published slug?

The old URL returns a 404 unless you add a 301 redirect from the old path to the new one. Set the redirect at the same time you change the slug, not afterwards.

What is URL Slug Generator?

URL Slug Generator converts a headline into a URL-safe slug: lowercase, accents folded to ASCII, punctuation removed and spaces replaced with hyphens. It is used when a CMS auto-slug is wrong, when planning a URL structure in a spreadsheet, or when migrating content between platforms.

How to use it

1Paste one headline per line — the tool slugs each line separately.
2Choose a separator, and optionally strip stop words to shorten the slug.
3Set a maximum length if your platform truncates long URLs.
4Copy the slugs into your CMS or migration sheet.

Features

Unicode accents folded to ASCII (café becomes cafe)
Ampersands expanded to 'and' rather than dropped
Consecutive separators collapsed and trimmed from both ends
Batch mode: every line in the input produces its own slug

When people use it

Planning a content calendar

Paste a quarter of planned headlines and get the exact URLs in one pass, so the sheet you hand to developers matches what ships.

Fixing an inherited URL

Auto-generated slugs frequently include dates, stop words or numeric suffixes. Regenerating a clean slug and adding a 301 keeps the URL readable without losing equity.

Known limits

Hyphen is preferred over underscore for search engines; underscore is offered for legacy systems that require it.
Removing stop words can change meaning — check slugs like 'best-of-the-year' before publishing.
