Is this free to use?
Yes. It is completely free, with no account, no signup, and no usage limits.
Does it work on a phone?
Yes. The page runs in any modern mobile browser, on iPhone and Android alike, with no app to install.
Do I need to install anything?
No. The tool runs entirely in the browser, so there is nothing to download or install.
Why does an extracted link end with a period?
The pattern keeps reading until it meets whitespace or a bracket, and a period is neither. A URL at the end of a sentence therefore captures the full stop. Delete the trailing period, or check the last character of every result before you use the list.
Why did it skip www.example.com?
A scheme is required. Without http or https at the front there is nothing for the pattern to anchor on, and matching bare domains would also match ordinary text like "file.txt" or "e.g". Add the scheme to those links first if you need them.
Why was my Wikipedia link cut short?
Parentheses end the match, and many Wikipedia titles use them for disambiguation. The URL is truncated at the opening bracket. Those links have to be collected by hand.
Does it remove duplicate links?
It removes exact duplicates only. The same destination reached via http and https, or with a trailing slash on one and not the other, will appear twice because the strings differ.
Can I pull the links out of an HTML page?
Only the ones that appear in the text you paste. If you copy the rendered page, you get the URLs that were written out visibly. To get every href you would need to paste the page source, in which case the pattern will find the URLs inside the quotes and stop cleanly at the closing quote.
Is my text uploaded anywhere?
No. The extraction runs in the browser, so an internal document, a private export, or a client's page copy is never transmitted.
