0 / 30,000 characters. No upload, storage, or account required.
Hreflang extraction workflows
Use hreflang extraction when alternate language annotations need a quick pasted-input inventory before localization or migration QA.
Compare canonicals
Pair this with Extract Canonical URLs to compare canonical and alternate annotations from the same head snippet.
Inspect page source
Use HTML Formatter before extraction when copied head markup is minified or difficult to scan.
Clean URL lists
Send copied rows to Remove Duplicate Lines, Filter Lines, or URL Parser for follow-up checks.
What this tool does
Extract Hreflang Tags finds rel=alternate hreflang links in pasted HTML, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract hreflang language codes and alternate URLs from pasted HTML head snippets, localization templates, copied page source, and migration exports before international SEO QA.
Use Extract Hreflang Tags when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste HTML head markup, copied page source, templates, locale switcher snippets, or migration exports that contain hreflang link tags.
- Choose whether duplicate language/URL pairs should be removed and whether language codes should be normalized.
- Review each extracted hreflang row with source lines, then copy the clean list for international SEO QA or documentation.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Hreflang tag extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML text you paste.
