Slug Generator

Turn any title or heading into a clean, URL-friendly slug in your browser. Romanize Chinese to pinyin, Japanese, Korean, Cyrillic, Greek, Arabic, and other scripts into readable ASCII, or keep the original characters for Unicode URLs. Choose the separator and casing, set a maximum length that trims on whole words, map symbols to words, drop common stop words, and process many lines at once with automatic de-duplication, then copy or download the result.

Overview

The tool converts arbitrary text into a safe URL segment, with control over how non-Latin scripts are handled, which separator and casing to use, and how length and duplicates are managed across many lines.

  1. 01

    Romanize non-Latin scripts

    Convert Chinese to pinyin, plus Japanese, Korean, Cyrillic, Greek, Arabic, Thai, and accented Latin into readable ASCII so the slug stays short and works everywhere, with accents and diacritics folded away.

  2. 02

    Accurate Chinese pinyin

    Chinese runs through a word-segmented pinyin engine that resolves polyphonic characters by context, so common names and phrases romanize correctly instead of one fixed reading per character.

  3. 03

    Keep Unicode when you want it

    Switch to Unicode mode to keep the original letters and CJK characters in the slug, cleaned of punctuation and spaces, for sites that serve internationalized URLs.

  4. 04

    Separator and casing control

    Choose a hyphen, underscore, dot, or no separator, and force lowercase, uppercase, or keep the original case to match your routing and style conventions.

  5. 05

    Length limit on word boundaries

    Set a maximum length and the slug is trimmed at the last separator before the limit, so it never ends on a half-cut word.

  6. 06

    Symbols, stop words, and custom rules

    Expand symbols such as the ampersand and at sign into words, drop common English stop words, and add your own replacement rules like mapping a currency sign to a word.

  7. 07

    Batch with de-duplication

    Paste many titles, one per line, and get one slug per line. Duplicate slugs get a numeric suffix so every result stays unique within the batch.

  8. 08

    URL preview, local only

    See the slug inside a full URL with its percent-encoded form, which is useful for Unicode slugs. Everything runs in your browser tab and is not sent to a server by this page.

How to use

Type or paste text on the left and the slug updates instantly on the right. Adjust the mode and options until the result matches your routing rules.

  1. 01

    Type or paste a title, heading, or filename. Add several lines to generate many slugs at once.

  2. 02

    Choose Romanize to convert non-Latin scripts to ASCII, or Keep Unicode to retain the original characters.

  3. 03

    Pick the separator and casing, and for Chinese text choose Auto, Pinyin, or Plain romanization.

  4. 04

    Optionally set a maximum length, expand symbols to words, or drop common stop words.

  5. 05

    Open Advanced to add custom replacement rules such as mapping a symbol or brand spelling to a word.

  6. 06

    Check the URL preview, then copy the slug or download every line as a TXT file.

Details

The right choice depends on your audience and stack. ASCII slugs are short and portable; Unicode slugs read naturally for non-Latin audiences but are percent-encoded on the wire.

  • Use Romanize for the broadest compatibility across CDNs, analytics, shells, and older systems that assume ASCII paths.
  • Use Romanize when a readable English-letter slug helps sharing, search snippets, and manual typing.
  • Use Keep Unicode when your audience reads Chinese, Japanese, Korean, or Cyrillic and your server handles UTF-8 paths.
  • Set Chinese to Pinyin to force pinyin even on text that also contains Japanese kanji.
  • Use a hyphen separator for web URLs, which search engines treat as a word boundary, and underscores mainly for filenames or anchors.
  • Set a max length around 60 to 75 characters to keep slugs readable and within sensible URL limits.

Use cases

Slugs show up anywhere a human-readable identifier has to live in a URL, a path, or a filename without spaces or unsafe characters.

  1. Blog and CMS post URLs

    Turn an article headline into a stable, readable URL segment for a blog, documentation site, or content platform before publishing.

  2. Multilingual content

    Romanize Chinese, Japanese, Korean, or Russian titles into ASCII slugs, or keep Unicode characters when the site serves internationalized URLs.

  3. Anchor and heading IDs

    Generate fragment identifiers for headings and table-of-contents links, matching the lowercase, hyphenated style most static site generators use.

  4. Filenames and asset keys

    Convert titles into safe filenames or object-storage keys without spaces, accents, or characters that break shells and URLs.

  5. Product and category handles

    Create predictable handles for products, tags, and categories in an e-commerce or catalog system, with de-duplication across a bulk import.

  6. API and database identifiers

    Derive readable keys, route parameters, or reference codes from human input while keeping them constrained to a safe character set.

When you need a fresh random token or word-based slug rather than one derived from existing text, the Random String Generator generates it directly. To reshape the casing of a title before turning it into a slug, run it through the Case Converter first. To see exactly how a Unicode slug is percent-encoded for the address bar, use the URL Encoder and Decoder , and to measure how long a title or slug is, paste it into the Text Counter for character and word totals.

Best practices

A good slug is short, stable, and readable. A few habits keep URLs clean and avoid breaking links once a page is published.

  • Keep slugs short and meaningful; trim filler words rather than encoding the entire title.
  • Use lowercase and hyphens for web URLs, since this is the convention search engines and routers expect.
  • Do not change a published slug, because changing it breaks existing links and bookmarks unless you add a redirect.
  • Ensure slugs are unique within a section; rely on the batch de-duplication when importing many titles at once.
  • For non-Latin audiences, decide between romanized ASCII and Unicode slugs once and apply it consistently across the site.

Limitations

A slug is a formatting convenience, not a guarantee. It cannot enforce uniqueness in your database or fix routing on its own.

  • A slug does not guarantee global uniqueness; your application still has to check for collisions before saving.
  • Romanization of Japanese kanji is approximate, since the same character can have several readings that need full context to resolve.
  • Keep Unicode slugs only work if your server, framework, and CDN accept UTF-8 paths; otherwise prefer romanized ASCII.
  • Stop-word removal uses an English list, so it will not trim filler words in other languages.
  • A slug is not a security control; never rely on an obscure slug to protect a private page.

FAQ

Answers to common questions about romanization, Unicode URLs, separators, and how the tool handles many lines.

What is a URL slug?

A slug is the human-readable part of a URL that identifies a page, such as the my-first-post part of a blog address. It uses lowercase letters, numbers, and hyphens so the link is clean, stable, and easy to read.

How does it handle Chinese, Japanese, and Korean?

In Romanize mode, Chinese is converted to pinyin with a word-segmented engine that handles polyphonic characters, while Japanese, Korean, Cyrillic, Greek, Arabic, and more are transliterated into readable ASCII. In Keep Unicode mode the original characters are preserved.

Should I romanize or keep Unicode characters?

Romanize for the broadest compatibility and short, portable ASCII URLs. Keep Unicode when your audience reads a non-Latin script and your server, framework, and CDN all accept UTF-8 paths. The URL preview shows how a Unicode slug is percent-encoded.

Can I generate many slugs at once?

Yes. Put one title per line in the input and the tool returns one slug per line. With the unique option on, any duplicate slugs get a numeric suffix so every result stays distinct within the batch.

Does the maximum length cut words in half?

No. When you set a maximum length, the slug is trimmed at the last separator before the limit, so it ends on a whole word rather than a partial one.

Is my text sent to a server?

No. The generator runs entirely in your browser tab. The text you enter, the slugs, and any downloaded file are not sent to a server by this page.
