How are accents and special characters handled?

Accented letters are normalized to their base form, so "Café" becomes "cafe", and any run of non-alphanumeric characters collapses to a single separator.

Can I convert many titles at once?

Yes. Each input line becomes one slug on the matching output line, so you can slugify a whole list of page titles in one pass.

Is my text uploaded anywhere?

No. Slugs are generated entirely in your browser with JavaScript, so your text never leaves your device.

Can I use underscores instead of hyphens?

Yes. Switch the separator option to underscore and spaces and punctuation are replaced with _ instead of -, useful for filenames and code identifiers.

Will the slug keep numbers?

Yes. Letters and digits are preserved, so "10 Tips for Sleep" becomes 10-tips-for-sleep. Only non-alphanumeric characters are converted to the separator.

Can I keep uppercase letters?

Yes. Lowercasing is on by default, but you can turn it off to preserve the original casing while still cleaning up spaces and accents.

Are leading and trailing separators removed?

Yes. A title that starts or ends with punctuation will not produce a slug with a dangling hyphen or underscore — those are trimmed from both ends.

Bulk Text to Slug Converter

Convert text to URL slugs in bulk

This bulk converter turns a list of titles into clean, web-safe URL slugs — one slug per line. It is built for content teams and developers slugifying a batch of blog posts, product names, page titles, or filenames in a single pass rather than one at a time.

How it works

Each line is processed independently. First, accents are removed by Unicode normalisation (NFKD) so Café becomes cafe. The text is optionally lower-cased, then any run of non-alphanumeric characters (spaces, punctuation, symbols) is collapsed into a single separator — a hyphen by default, or an underscore if you choose. Finally, leading and trailing separators are trimmed so no slug starts or ends with one.

slug = deaccent → (lowercase) → non-alphanumeric runs → separator → trim ends

Example

Input:

Hello, World!
10 Tips for Better Sleep
Café René — Opening Soon

Output with the hyphen separator and lowercasing on:

hello-world
10-tips-for-better-sleep
cafe-rene-opening-soon

Everything runs locally in your browser — nothing is uploaded, so your draft titles stay private.
