What this does

Converts titles and phrases into slugs for URLs, file names, and identifiers. Type one title per line to get one slug per line.

How a slug is built

Accents are removed (Café becomes Cafe), and ß, ø, æ and similar letters are transliterated.
Apostrophes are dropped, so It's becomes Its rather than It-s.
Everything that is not a letter or digit becomes a single separator, and separators at the ends are trimmed.
The result is lowercased and, if you set a maximum length, cut to that length without leaving a dangling separator.

Separator: hyphen (best for URLs) or underscore (common for file names and database keys).
Lowercase: turn off to keep the original capitalization.
ASCII only: drop every character outside A to Z and 0 to 9. By default letters from other scripts, such as Cyrillic or Chinese, are kept. If you need a purely ASCII URL for such a title, enter an ASCII alternative yourself, since this tool does not translate between scripts.
Max length: 0 means no limit.

Hello, World! It's a Café Menu — 10 Best Ideas becomes hello-world-its-a-cafe-menu-10-best-ideas.

For other identifier styles such as snake_case or kebab-case from existing names, use the Text Case Converter.
