FAQ
What counts as a valid slug here?
By default: lowercase letters, numbers, and hyphens only, no leading/trailing hyphen, no double hyphens, and within the max length.
Can I check multiple slugs at once?
Yes—paste one slug per line and click Check.
Does this tool generate a new slug or only validate?
It does both: validation plus a suggested “fixed” slug, and Fix & Replace can overwrite your input with the suggestion.
What does ASCII-only mean?
ASCII-only removes accents/diacritics and limits characters to a-z, 0-9, and - (more consistent across platforms).
Should I allow slashes?
Only if you’re validating a path like category/product-name; for a single slug segment, keep it off.
Will this change my existing URLs automatically?
No—this runs client-side and only outputs suggestions; updating URLs and redirects is up to your CMS/server.
Is any text I paste sent to a server?
No—checking and fixes run in your browser; there are no network calls in the tool.
