Create a Free Short Link with QR Code in Seconds

What is a Short Link?

A short link is a compact URL that redirects visitors to a longer destination address. Instead of sharing a 200-character link filled with tracking parameters and directory paths, you share something like kwy.uk/abc123 — clean, readable, and easy to type from memory.

Short links are used everywhere: social media profiles where space is limited, QR codes printed on packaging and flyers, email newsletters where long URLs break across lines, and SMS campaigns where every character counts. You can also use KWY to shorten any URL instantly without creating an account.

How KWY Short Links Work

When you create a short link on KWY, the service generates a unique 6-character code drawn from a 62-character alphabet (uppercase letters, lowercase letters, and digits). This gives over 56 billion possible combinations, making collisions extremely unlikely even at high volumes.

When a visitor clicks your short link, KWY looks up the code in its database and immediately issues an HTTP 302 redirect to the original destination. The entire process takes milliseconds. KWY is a free link shortener with no interstitial pages or forced waiting — unless you specifically configure a redirect delay for your deployment.

The Delete Link — Your One-Time Secret

Most free URL shorteners give you no way to remove a link after creation. KWY is different. Every short link comes with a 64-character cryptographically random delete token, shown to you once immediately after creation. Save this link — it is the only way to remove your short URL.

Using the delete link marks the short code as permanently removed. Anyone who visits the deleted short link receives an HTTP 410 Gone response — not a 404, which could suggest the link never existed. This distinction matters for anyone who shared the link and wants recipients to know it was intentionally removed. Learn more on the About KWY page.

Short Link + QR Code — Automatically

A short link and a QR code solve the same problem from different angles: both make long, complex URLs accessible in contexts where typing is impractical. KWY combines them automatically. Every time you create a short link, a QR code is generated at the same time — no need to open a separate QR code tool.

Short URLs produce significantly better QR codes than long ones. QR codes work by encoding data into a grid of squares — the more data, the denser and harder to scan the pattern becomes. A 200-character URL creates a QR code that is difficult to scan in poor lighting or at small print sizes. A compact kwy.uk/xxxxxx link produces a clean, open pattern that scans reliably every time, even on a business card or a small product label. Once created, download the QR code as PNG or share it directly from your phone to WhatsApp, Telegram, or any other app.
