Note

Letters and digits (including Korean) are preserved; everything else collapses into the separator. Accent stripping removes combining marks only (Café → Cafe) — romanization is not supported.

Usage / FAQ

When to use

  • Generate URL slugs from blog post titles
  • Clean up Korean titles into Unicode-preserving slugs
  • Brainstorm GitHub repo / npm package names
  • Produce consistent filenames for Notion / Confluence exports
  • Normalize image filenames by stripping special characters

FAQ

Q.How are Korean characters converted?
A.Korean is preserved as-is (NFC-normalized). Modern browsers and search engines support Unicode URLs; external shares may percent-encode them. Romanization (안녕 → an-nyeong) is not supported.
Q.What about duplicate slugs?
A.This tool doesn't deduplicate. Append `-2`, `-3` in your DB logic if needed.
Q.Emojis and special characters?
A.Emojis and symbols are stripped. Letters, digits (including Korean), and your chosen separator remain.
Fun facts

  • The 'slug' in URL slug comes from the newspaper printing era — a 'lead slug' was a small piece of metal used to identify or sort an article. The 'short, human-readable identifier' meaning was carried over to blogs and CMSs in the late 1990s as URLs became human-readable.

    Wikipedia — Clean URL slug

  • For SEO, a URL slug should summarize the page's content. Google uses words in the URL as a weak ranking signal — `/articles/how-to-bake-bread` gets a slightly higher click-through rate than `/articles/12345` since users actually read the URL.

    Google — URL Structure

  • Whether to embed Unicode Korean / CJK characters in slugs directly vs Romanize (e.g., '안녕하세요' → 'annyeonghaseyo') is a long-running debate. Native characters align with IDN display, but external sites can mangle them via percent-encoding (`%EC%95%88...`) — which is why Korean blogging platforms split between native vs Romanized.
