The friendly URL toolkit

Stretch. Shrink. Share.

Slinkr turns unwieldy links into short, shareable ones — and does the reverse, too. Expand mystery URLs before you click, generate QR codes with your own logo, and check whether a link is alive, redirected, or broken. One clean page, four tools.

Real QR — scan to try Slinkr

Four tools, one page

Shrink

Shorten URLs

Turn long, fragile links into short ones that fit in a slide, an email, or a printed handout — and never break mid-wrap again.

Stretch

Expand URLs

Been handed a shortened mystery link? Paste it in and see exactly where it leads before you click. No account required.

QR codes with your logo

Generate crisp, scannable QR codes for any URL — optionally with your own logo in the centre. Download as PNG, free for everyone.

Check

Link health checks

Is it alive, redirected, or dead? Check any link's HTTP status and final destination before you share it with a hundred people.

Small, honest, self-hosted

Your links, your server

Slinkr runs on our own infrastructure — not a link-tracking service. No ads, no click profiling, no selling your audience to anyone.

Spam-resistant by design

Shortening requires a verified account, approved by a human admin. That keeps Slinkr links trustworthy — a short link from here isn't hiding anything nasty.

Open source

MIT-licensed Flask app you can read, audit, or run yourself — a Docker image is one docker compose up away.

Try it without signing up

Two of the four tools are open to everyone, no account needed. If you like what you see, registration takes thirty seconds — and once an admin verifies you, the whole toolkit is yours.
