Generate URL slugs

Most slug generators delete Japanese entirely and leave you with an empty slug. This one transliterates kana to romaji, so 「とうきょうのしゃしん」 becomes a slug you can actually use.

Why nothing is uploaded

Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.

Verify it yourself

Open your browser’s developer tools (F12) and select the Network tab.
Load your file and run the tool.
The only requests you will see are the tool’s own code and, once cached, none at all.

Frequently asked questions

What happens to kanji?

It is kept as-is. Reading kanji correctly needs a dictionary and context — 東京 is とうきょう but 東 alone is ひがし — and guessing would produce confidently wrong slugs. Kanji in a URL is valid and works; if you want pure ASCII, replace them yourself.

Should a slug be in Japanese or romaji?

Either works technically. Japanese in a URL is percent-encoded when shared, turning a clean address into a wall of %E6%9D%B1 — which is why many Japanese sites use romaji or English slugs even for Japanese content.
