Free QR Code & Barcode Generator

Q: Do the QR codes expire?

No. They are static codes: your link, text, contact, or credentials are encoded directly into the modules of the code itself, not behind an external redirect service. There are no expiration dates or redirect outages.

Q: Is my data uploaded anywhere?

No. Codes are generated completely inside your browser using client-side JavaScript. Wi-Fi passwords, contact cards, private notes, and internal product numbers never leave your device or touch a server.

Q: Can I use these barcodes on products in stores?

Yes, if the number is authorized. Retailers and marketplaces like Amazon expect product GTINs licensed from GS1. UniversalCodeMaker draws the compliant optical symbol and verifies check digits; the number itself must come from GS1 or your retail channel.

Q: Can I generate barcodes in bulk from an Excel or CSV file?

Yes. The Bulk Barcode Generator tool allows you to paste or upload spreadsheets with up to 200 items to export a consolidated ZIP of vector SVGs or print-ready 30-up Avery PDF sheets.

Common questions

Is it really free?

Yes. Every format, download size and label sheet is free, with no sign-up and no watermark. The site is supported by clean advertising and affiliate partnerships.

Do the QR codes expire?

No. They are static codes: your link or text is stored in the code itself, not behind a redirect service, so nothing on our side can make them stop working. To change what a code says, make a new one.

Is my data uploaded anywhere?

No. Codes are made in your browser, so Wi-Fi passwords, contact details and product numbers never leave your device.

Can I use these barcodes on products in stores?

Yes, if the number is yours. Retailers and marketplaces such as Amazon expect product numbers licensed from GS1. We draw the barcode and calculate its check digit; the number itself has to come from GS1 or your retailer. Step by step: how to get a barcode for your product.
