Extract all URLs and links from any text content. URL Extractor is a free online tool from the ToolsRift Text Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
http://, https://, ftp://, and bare www. domains are all detected.
Optional — duplicates can be removed or kept with counts.
Not directly, but you can copy and use the URL Slug tool on each result.
