One button on your bookmarks bar
A bookmarklet is a bookmark whose address is a small piece of JavaScript. You drag it to your bookmarks bar once, and from then on clicking it on any page opens a small window with that page's URL and title already filled in. It is the oldest trick on the web and it still beats an extension.

Get started
Sign up and drag the button to your bar — it takes about thirty seconds.
Why not an extension
A browser extension that can save the page you are on is an extension that can read every page you visit, and it updates itself silently forever. A bookmarklet only does something when you click it, only sends the URL and the page title, and there is nothing installed to trust. It also works the same way in every desktop browser.
What it sends
The address of the page and its title, and nothing else. The page contents are never read and never leave your browser — the title comes straight from the tab, which is why this site never has to fetch the page itself.
Click it twice on the same page
If you have already saved a page, clicking the bookmarklet again opens that bookmark for editing rather than complaining about a duplicate. It is the fastest way to add a tag you thought of afterwards.
Questions
Which browsers does it work in?
Every desktop browser — Chrome, Firefox, Safari, Edge and the rest. Bookmarklets are a standard feature, not something this site invented.
Do I need to install anything?
No. You drag a link onto your bookmarks bar. There is nothing to install, no permissions dialog and nothing running in the background.
Does it work on mobile?
Poorly — mobile browsers make bookmarklets hard to reach. On a phone, paste the URL into the save form or add the site to your home screen.
