QR Code Generator

What is a QR code generator?

A QR code generator turns a link into a small square barcode that any phone camera can scan to open it instantly. No typing, no searching. It's the fastest way to get someone from a printed flyer, business card, menu, or product label straight to a website. This one runs entirely in your browser: the link you paste and any logo you upload never get sent to a server, so there's nothing to upload and nothing to wait for.

To create a QR code, paste your link into the box above and watch the preview update as you type. Pick a QR color and a background color to match your brand, or leave the defaults for the most reliable scan. Want your logo in the middle? Upload a PNG or JPG and Multio centers it automatically, adds a small white margin so it doesn't blend into the code, and boosts the code's error correction so it still scans cleanly even with part of the pattern covered. When you're happy with it, download it as a PNG or JPG for quick sharing, or as an SVG if you need a crisp version for print at any size.

Does a QR code expire?

No. The QR code you generate here is static: the link is encoded directly into the pattern itself, so it works for as long as the destination page exists, with no expiration date and no tracking service in between.

PNG, SVG, or JPG: which should I use?

PNG is the safe default: it's sharp and supports a transparent-free, solid background, good for websites and documents. SVG is a vector format, so it stays perfectly crisp no matter how large you print it, ideal for posters, packaging, or signage. JPG works everywhere but always has a solid background fill, since it can't support transparency.

Why does contrast matter for QR codes?

Scanners read a QR code by telling its dark and light modules apart. If your QR color and background color are too close in tone, cameras struggle to lock onto the pattern, especially in bad lighting. Multio warns you when your color choice is too low-contrast to scan reliably, so you catch it before you print or publish.
