How to Use URL Title Collector

URL Title Collector lets you fetch <title> tags from multiple URLs at once using a lightweight, privacy-friendly mechanism that runs in your browser + Cloudflare Worker.

1. Basic Steps

• ① Paste URLs into the text area (one per line)
• ② Click “Fetch Titles”
• ③ Results (URL / title / status) appear in a table

Results can be copied as CSV or TSV. You can reset the tool anytime.

2. Status Types

• success — title fetched successfully
• no-title — page fetched but has no <title>
• http-error — 404 / 500 / other HTTP errors
• network-error — CORS, DNS, CSP, or other access issues

3. Supported Cases

• Standard HTML pages
• Blogs, news articles
• Pages with a <title> tag

4. Not Supported

• Login-required pages
• PDF / JSON / XML (non-HTML)
• Sites with very strict CSP rules
• Sites where JavaScript dynamically changes the title

5. CSV / TSV Output

The result table can be exported as CSV or TSV. Works with Excel, Google Sheets, Notion, Airtable, etc.

6. FAQ

Q: Why does a 404 page sometimes return a title?
Because the server returns a custom “Not Found” HTML page that still contains a <title> tag.

Q: Why do foreign sites fail more often?
Many overseas sites enforce strict CORS/CSP policies that prevent Workers from retrieving HTML.

Q: How many URLs can I process?
100–300 is recommended (depends on your device performance).

7. Disclaimer

The tool runs locally + via Cloudflare Worker. No URL or result is stored. Some URLs may not be retrievable due to CORS/CSP restrictions.
