Searching for a free QR code generator returns dozens of tools that look identical. Most are fine for a quick test, but a few have traps that only show up after you have printed a thousand flyers. This checklist helps you tell the difference in about two minutes.

1. Is the code static or dynamic?

A static QR code contains your link directly. It works forever and needs no account. A dynamic code contains a short redirect link owned by the generator, which lets you change the destination later and see scan counts — but it can stop working if the service or your plan ends. Read our static vs dynamic guide for the full trade-off. For menus, WiFi, contact cards and most print jobs, static is the safer choice.

2. Does it need an account?

If you must sign up just to download a PNG, the tool is collecting your email as the price. A generator that works instantly in the browser is easier to trust and faster to use.

3. Is there a watermark?

Check the downloaded file, not just the preview. Some tools show a clean code on screen and add a logo or text to the export. A watermark on a printed menu or business card looks unprofessional and can interfere with scanning.

4. Will the code expire?

Free trials are the most common trap: the code scans for 14 days, then redirects to an upgrade page. This only happens with dynamic codes. If the code contains your actual link, it cannot expire.

5. Can you download SVG as well as PNG?

PNG is fine for screens. For print, an SVG is better because it stays sharp at any size, from a business card to a banner. If a generator only offers a small PNG, you will struggle with large prints.

6. Can you customize it without breaking it?

Colors, dot shapes and a center logo are useful, but they must not reduce scannability. A good generator raises the error-correction level when you add a logo, and lets you check contrast. See how to add a logo without breaking the code.

7. What happens to your data?

Some generators send every link and WiFi password to their servers. For anything private, prefer a tool that generates the code in your browser, so what you type never leaves your device. BestQR works this way.

8. Does it have the type you need?

A plain URL code is easy, but WiFi, vCard, calendar events and payments each need a specific format. Dedicated generators fill these in correctly so phones recognize them. Browse the full list of QR code types.

9. Can you test it before you print?

Whatever tool you use, scan the final file with two phones before printing. The QR code validator and size calculator help you check readability and choose a print size.

Frequently asked questions

Is a free QR code generator really free?

Many are, but check for watermarks, expiry and sign-up walls. A generator that creates static codes in your browser has no running cost per code, so it can be free without catches.

Do free QR codes expire?

Static QR codes never expire because the link is stored inside the code. Only dynamic codes, which depend on a redirect service, can stop working.

Can I use free QR codes commercially?

With BestQR, yes. Codes you create are yours to use on any product, print or website, with no attribution required.
