What Is the Difference Between a Barcode and a QR Code?
A traditional barcode (such as CODE128, CODE39, EAN-13 or UPC-A) stores data in a single line of parallel bars of varying widths, read in one direction. It typically holds a small amount of information — most often a numeric product code — and is the backbone of retail point-of-sale and inventory systems worldwide.
A QR code (Quick Response code) is a two-dimensional matrix barcode that stores data both horizontally and vertically, allowing it to hold far more information: full web addresses, Wi-Fi credentials, contact cards, emails, SMS messages and more. QR codes also include built-in error correction, so they can still be scanned even if part of the code is damaged, dirty, or covered by a logo — which is exactly what makes logo embedding possible.
Practical Business Use Cases
- Retail & Inventory: Generate EAN-13 or UPC-A barcodes for product packaging, price tags and warehouse tracking.
- Restaurants & Cafés: Create a QR code that links to a digital menu, saving printing costs and enabling instant updates.
- Marketing & Packaging: Add a branded QR code with your logo to flyers, business cards and packaging to drive traffic to a landing page.
- Events & Hospitality: Share a Wi-Fi QR code so guests can connect instantly without typing a password.
- Networking: Encode a vCard QR code on your badge or business card so people can save your contact details with one scan.
- Logistics & Asset Tracking: Use CODE128 or ITF barcodes to label shipments, pallets and internal assets.

Frequently Asked Questions
Is this QR code and barcode generator really free?
Yes. This is a completely free online QR code generator and barcode maker with unlimited use — there are no hidden fees, watermarks, or sign-up requirements.
Do my QR codes expire?
No. The QR codes and barcodes generated here are static — the data is encoded directly into the image itself, entirely in your browser, so there is no expiration date and no external server involved.
Can I add my logo to the center of a QR code design?
Yes. Upload a PNG, JPG, WebP or SVG logo and it will be placed in the center of the QR code. We recommend using a High error-correction level when adding a logo so the code remains easily scannable.
Which barcode format should I use for retail products?
For retail point-of-sale, EAN-13 is the international standard and UPC-A is the standard in the United States and Canada. CODE128 and CODE39 are better suited for internal tracking, logistics and asset labels since they support letters as well as numbers.
Is my data uploaded to a server?
No. Every QR code and barcode is rendered entirely client-side, in your own browser. Nothing you type — including Wi-Fi passwords or contact details — is ever sent to or stored on a server.
