Free link tools

Handy tools you can use right now, without an account — useful on their own, and a taste of what the product does. The UTM builder runs here on Shortlen; the others open the free tools on the product site, b1.lc.

UTM builder

On Shortlen

Add campaign tags (source, medium, campaign and more) to any link and copy the result. It runs in your browser — nothing you type is sent anywhere.

Link checker

On b1.lc

Run the main pre-send checks on any link — is the destination safe and reachable, does it load over HTTPS and on mobile, is the preview right — a limited number of times per hour.

Link preview checker

On b1.lc

See the card a page will show when it's shared on WhatsApp, Facebook, LinkedIn, X or Slack — the title, description and image — and what to fix if it looks wrong.

QR code decoder

On b1.lc

Drop in a photo or screenshot of a QR code and see what it contains before you open it. The image is read in your browser and never uploaded.

Preview any short link with a "+"

Add a plus sign to the end of a BN Shortener link — for example b1.lc/AbC9+ — to see where it goes, without opening it: the destination, its title and when it was made. Nothing is counted, and password-protected or blocked links never reveal their destination.

Want all of this on your own links?

These tools are free and need no account. When you're ready to shorten, brand and measure your own links, start free or see the features.
