1 · What should it do?

2 · Content · Website link

This code contains: a link to this page, until you add content.

The exact text a scanner reads. No link through our servers, so it works for as long as your content does.

Everything happens in your browser. Nothing is uploaded, nothing is stored, and this code can never expire. How we do that.

Shows what is inside

Before you download, the page shows the raw text a scanner will read. No hidden short-link, no surprise redirect.

Tells you if it won't scan

An independent decoder test-scans your design. Contrast, logo size, inverted colours and print size are checked before you print.

Any size, real vectors

PNG at whatever width you type, up to 16K and beyond. SVG, PDF and EPS for print shops. Nothing is ever upscaled.

Questions

Will my QR code expire?

No. Every code contains your content directly: the link, the WiFi details, the contact card. There is no redirect through our servers and no subscription that can lapse, so nothing about it can expire. It works for as long as the thing it points to exists.

Why is this free when other generators charge?

Because there is no server. The code is generated entirely in your browser, so there is no rendering bill for us to recover and nothing to put behind a paywall. The site carries a few ads and that covers hosting.

Is there a size limit or a watermark?

No. Download PNG at any pixel size you type, up to 16K and beyond, or SVG, PDF and EPS vectors. No watermark, ever.

Do you track scans?

We cannot. A static code goes straight from the phone to your content; we are not in between. That is the trade: no analytics, but also no way for anyone to switch your code off.

Can I edit the code after printing?

No static code can be edited after printing. If you expect to change the destination, point the code at a page you control and change that page.

Do I need an account?

No. Nothing is stored, so there is nothing to sign in to.
