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
Completely free, no registration required. Type a title in your browser to generate a URL slug — all operations run locally with no usage limits.
It supports hyphen (-) and underscore (_) — the two most common separators. You can switch freely before generating, to match different website or framework URL conventions.
The tool strips punctuation and other non-conventional characters, converts spaces to the chosen separator, and lowercases letters by default to produce clean, URL-friendly slugs.
CJK characters (Chinese, Japanese, Korean) are preserved as-is in the slug. If your site uses CJK URL paths, you can generate slugs that fit those conventions directly.
