Usage Guide
Titles to URL slugs, article path generation, anchor identifiers — URL-hostile characters like underscores, spaces and CJK must be normalized. This tool applies standard slug rules: lowercase, spaces to hyphens, special characters stripped, with custom delimiters. Fully local, SEO- and routing-friendly.
1. How to use
- Paste the title or phrase (CJK or English) into the input area.
- Choose the delimiter (hyphen - by default) and case strategy (all-lowercase / preserve case).
- Copy the slug for URLs, filenames or component keys.
2. Difference from slugify
- This tool focuses on standard URL slugs — CJK input gets compatibility handling with ASCII output preferred.
- For Chinese-to-pinyin conversion use slugify, which ships a dedicated pinyin option.
- Delimiter choice: hyphens for URL paths (SEO convention), underscores for code identifiers (avoid minus-sign ambiguity).
- Normalize to lowercase — most CDNs and static servers are case-sensitive; mixed case invites 404s.
3. Quality checks before shipping
A good URL slug is short (no long tails), readable (keeps meaningful keywords, no cryptic abbreviations), and stable (does not change when the title changes). Evaluate stop words (a, the, 的, 了) — some frameworks strip them automatically, but dropping "the" sometimes loses semantics. The full workflow — lowercase, dedupe, date-prefix for blogs — starts here; feed multiple title lines through line-batch-processor to scale it.
FAQ
Free and login-free, available anytime. The title-to-slug conversion happens entirely within the page and leaves no server-side trace.
Hyphen (-) and underscore (_) — the two conventions you will meet most. Switch between them before generating to match your site or framework's URL naming style.
Punctuation and other unconventional characters are stripped, spaces become the chosen separator, and letters are lowercased by default, yielding clean, URL-friendly slugs.
CJK characters (Chinese, Japanese, Korean) are preserved as-is in the slug. If your site uses CJK URL paths, you get standards-compliant slugs directly; whether to transliterate or use pinyin is a site-policy decision.
Yes — set up redirects and update internal links plus the sitemap in the same pass. Also remember a slug is just one piece of the URL: overall SEO depends on the site's information architecture. Overlong slugs hurt sharing, and keyword stuffing does not improve indexing.
Agree on the rules first — transliteration or pinyin for Chinese titles, which separator, a length cap — write them into a one-minute checklist, then batch-generate. And never bake secrets or session ids into a public slug.
