QR code

A QR code is a two-dimensional barcode a phone camera can scan to open a link, join WiFi, save a contact or more. Because scanning is instant, QR codes bridge print and physical spaces to the web. Urlik generates free QR codes for URLs, WiFi, vCards, email, SMS and geo, in PNG or crisp SVG.

URL shortenerA URL shortener turns a long web address into a compact link that redirects to the original. Shorteners save space, look cleaner in messages and social posts, and — when they log each visit — add click analytics the raw link never had. Urlik shortens links for free with custom aliases, expiry, passwords and per-link statistics.301 vs 302 redirectA 301 redirect is permanent: it tells browsers and search engines the destination has moved for good, and it passes almost all ranking signals to the new URL. A 302 redirect is temporary: the original stays canonical and signals are not fully transferred. For short links you usually want a 302 unless you are permanently retiring the old address, so the destination — not the short link — accumulates authority.UTM parametersUTM parameters are tags added to a URL (utm_source, utm_medium, utm_campaign, utm_term, utm_content) that tell analytics tools where a visit came from. They let you separate traffic from an email, an ad and a social post even when all point to the same page. Urlik can append UTM tags to any short link automatically so every campaign is measurable.Vanity URLA vanity URL is a short, human-readable custom link — like urlik.xyz/sale — chosen instead of a random code. Vanity links are easier to remember, safer-looking and reinforce a brand every time they are shared. Any Urlik link can use a custom alias to become a vanity URL.
