Appearance

Your QR code

Fill in the form to make your code.

Made in your browser: nothing you type is sent to Surftec or anyone else. The code links straight to your content, with no tracking or redirect, so it never expires. Always scan a test print before you use it.

About this tool

Many free QR code sites send your code through their own short link, so it stops working when the free trial ends, and they track every scan. Codes made here hold your link or details directly, so they never expire and nobody tracks them.

Common questions

Which file should I download?

SVG for print and design work: it stays sharp at any size. PNG for documents, emails and websites.

How big should a printed QR code be?

At least 2 cm across for scanning at arm's length. Allow about 1 cm of width for every 10 cm of scanning distance.
