Question 1

Is this QR code generator really free?

Accepted Answer

Yes. Static QR codes are free forever on JustQRs — full designer, unlimited PNG and SVG downloads, no watermark, no expiry, and no signup for this page. The code is generated right in your browser; nothing you type here is uploaded or stored.

Question 2

Do the QR codes expire or stop working?

Accepted Answer

Never. A static QR code encodes your content directly in the pattern — it has no dependence on JustQRs or any other service, so it works as long as the print does.

Question 3

Should I download PNG or SVG?

Accepted Answer

SVG for anything going to print — it's a vector, so it stays sharp at any size. PNG for screens, documents, and quick sharing. Both are free and watermark-free.

Question 4

Can I add my logo to the QR code?

Accepted Answer

Yes — pick a logo file in the designer and it's embedded in the middle of the code. On this page the file never leaves your browser. Error correction is raised automatically so the code still scans reliably.

Question 5

What's a dynamic QR code, and when do I need one?

Accepted Answer

A static code can't be changed after it's printed. A dynamic code points to a short link you control, so you can change the destination anytime and see analytics on every scan. If the code is going on menus, packaging, or campaign print, dynamic is usually worth it — that's what the paid plan adds.

Design a QR code. Download it. Done.

A static code can never change its mind.

Fair questions.
