What is URL Extractor?

About URL Extractor This tool will extract all URLs from text. It works with all standard links, including with non-English characters if the link includes a trailing / followed by text. This tool extracts all URLs from your text. If you want to remove duplicate URLs, please use our Remove Duplicate Lines tool.

Embed.ly has a nice api for exactly this purpose. Their api returns the site's oEmbed data if available - otherwise, it attempts to extract a summary of the page like Facebook.
