Enter URLs for each language version of the same content. The URL input fields are wide enough for practical SEO work.
Recommended Structure
If Korean, English, and Japanese pages provide the same content, it is recommended to add the same hreflang tag set to the head section of every language page. Absolute URLs starting with https:// are recommended instead of relative paths.

Deploying a consistent hreflang set across language versions
Generate alternate links for equivalent language or regional pages. Each version should publish the complete set, including itself, so reciprocal relationships can be checked after deployment.
When to use this tool
- Connect equivalent Korean, English and Japanese pages.
- Add a deliberate x-default fallback.
From input to a checked result
- 1
List the final URLs for equivalent content.
- 2
Select each supported language or language-region code.
- 3
Enter a full HTTP(S) URL without credentials.
- 4
Add x-default only when a suitable fallback exists.
- 5
Generate the set and insert it into every alternate page.
- 6
Check self references, reciprocal links and live response status.
Two languages
- Input
- en: https://example.com/en/; ja: https://example.com/ja/
- Result
- Two alternate link tags
Place both tags on both pages, including each page's own URL.
An intentional fallback
- Input
- Two language entries plus automatic x-default
- Result
- Three tags; x-default reuses the first URL
Confirm that the first entry is the desired fallback before enabling this option.
How it works
The editor accepts up to 50 rows from its language list. It rejects duplicate codes, URLs over 2,048 characters and URLs with credentials or a non-HTTP(S) scheme. Automatic x-default uses the first nonempty entry when no x-default was entered.
Limitations
- The tool does not fetch pages or verify reciprocal deployment.
- Language codes outside the dropdown cannot be entered.
- Equivalent meaning and translation quality require human review.
Your data
URLs are converted to tags in your browser without being saved to win-j.

- Canonical URL Checker
Find missing, duplicate and questionable canonical links before publishing. The checker reads supplied HTML; it cannot confirm which canonical URL a search engine has selected.
- sitemap.xml Generator
Convert a URL list into XML, resolving relative paths and removing duplicates. Select canonical, indexable pages before generating the file; the tool cannot verify their live status.
Frequently asked questions
Do I include the current page?
Yes. Each page should list itself alongside the other versions.
Is x-default required?
No. Use it when you have a deliberate language-neutral or fallback destination.
Can the alternate pages use different domains?
Yes. Use full URLs and deploy reciprocal references; this tool does not check those pages.
