• Free QR Codes With Ads: What Your Guests Actually See — You printed a free QR code. Your guests scanned it and got an ad first. Here is how that happens and how to avoid it. (2026-11-06)

Before you print a QR code

1. Will people who scan it see ads? Look for the words ads, sponsored or interstitial in the free plan, then scan a test code on a phone that has never used the service.
2. What happens when a trial ends or you stop paying? Some services switch dynamic codes off or send every scan to an upgrade page.
3. Can you change where the code points after printing? That is the reason to choose a dynamic code at all.
4. Can you export your links? You want your codes and their destinations in a file you keep.
5. Who runs the address inside the code? Every scan passes through it, so it should belong to a service you trust to still be there next year.

If the code never needs to change, a static code from the free QR code generator has no middleman at all and needs no account. If you want to edit it after printing, DexURL makes dynamic codes on a free plan with no ads on the scan.
