Frequently asked questions
Are the QR codes created here free?
Yes. Every generator on this site is free with no account, no watermark and no locked features. There is no paid tier.
Do the QR codes expire?
No. These are static codes, which means your data is stored inside the pattern itself rather than behind a redirect someone else operates. There is nothing to renew and nothing that can be switched off.
Is my data uploaded to your servers?
No. Encoding, decoding, image processing and ZIP building all happen in your browser. Links, Wi-Fi passwords, contact details, barcode numbers and uploaded images are never sent to us.
Can I use the codes commercially?
Yes. Codes you generate are yours to use, including on products and packaging. Note that generating a UPC or EAN image does not register an official product number — those are issued by GS1.
What is the difference between a QR code and a barcode?
A traditional barcode is one-dimensional: bars and spaces read across, usually holding a short number. A QR code is two-dimensional, read in both directions, and holds far more data including text, links and Wi-Fi credentials.
Can I download SVG files?
Yes. Every generator offers SVG as real vector output, so the code stays sharp at any size. PNG, WebP, JPG and a print-sized PDF are also available.
Why is my QR code not scanning?
Usually size, contrast, a missing quiet zone or a blurred print. The generator rates all four before you download, and the guide "Why is my QR code not working?" walks through the rest.
What barcode type should I use?
UPC-A for retail in the US and Canada, EAN-13 elsewhere, ITF-14 for shipping cartons, GS1-128 when you need batch or expiry data, and Code 128 for internal inventory. The barcode types guide compares them all.
