URL Slug Generator (Thai-aware)

Create clean, SEO-friendly URL slugs from any Thai or English title in one step. Because Thai has no spaces, this tool uses your browser's Thai word segmentation to drop hyphens between real words — so การตลาดออนไลน์ becomes การตลาด-ออนไลน์ instead of one unreadable string. You see both the human-readable slug and the percent-encoded form that actually appears in your URLs. It is free, needs no sign-up, and runs entirely in your browser.

Paste an article title or product name — Thai, English or both.

Slug mode

Keeps Thai words and adds hyphens at word boundaries — recommended for Thai SEO.

Transliterates Thai to Latin letters. Approximate only — always double-check the result.

Drops every non-Latin character and strips accents. Best for English titles.

Options

Google treats hyphens as word breaks — hyphen is the safer default.

Trimmed at the nearest word boundary so no word is cut in half.

Frequently asked questions

Are Thai characters allowed in a URL slug?
Yes. Modern browsers and Google support Thai characters in URLs, and a readable Thai slug can help click-through and relevance for Thai audiences. The slug is stored percent-encoded (for example การตลาด becomes %E0%B8%81…), which the tool shows alongside the readable form.
How does it split Thai words with no spaces?
It uses your browser's built-in Thai segmentation (Intl.Segmenter) to find word boundaries, then joins the words with your chosen separator. Segmentation is very good but not perfect for names and brands, so you can edit the slug directly afterwards.
Why is the encoded slug so much longer than the readable one?
Each Thai character becomes three percent-encoded bytes (for example %E0%B8%81), so a Thai slug is roughly three times longer once encoded. The tool warns you when the encoded length passes 200 characters so your URLs stay manageable.
Is the romanization accurate?
It is approximate. Romanize mode uses a simplified RTGS-style map and drops tone marks, so it will not match every official spelling. Use it as a starting point and review the result before publishing.
Should I use hyphens or underscores in a slug?
Hyphens. Google treats a hyphen as a word separator but an underscore as a word joiner, so hyphens generally give better results for SEO. The hyphen is the default here.
