A free, privacy-first tool for batch link extraction, validation, and export. All processing happens locally in your browser — nothing is uploaded to any server.
- Batch URL Extraction — Automatically extract all links from plain text and multiple file formats (TXT, JSON, MD, HTML, XML, CSV, JS, TS, JSX, TSX)
- Link Validation — Concurrently check each link's availability with 5 threads; detect success, failure, and timeout with HTTP status codes
- Multiple Export Formats — Export results as TXT, JSON, or CSV for data analysis, documentation, and reporting
- Smart Filtering — Filter links by status: all, valid, invalid, pending
- Re-verification — Re-check individual failed or timed-out links without re-extracting everything
- Domain Grouping — Group links by domain for organized browsing
- Search — Search through extracted links by URL
