What you should know
Product labeling requires exact barcode formats depending on your sales channel and logistics setup. Standard retail marketplaces like Amazon, or regional platforms like Trendyol, the largest marketplace in Turkey, reject invalid EAN-13 codes when check digits fail mathematical validation. Internal warehouse systems and shipping labels rely on alphanumeric Code 128 symbologies rather than standard retail numbers to track custom stock keeping units. Meanwhile, QR codes used on retail packaging often fail at physical print sizes if data payloads exceed optimal density or lack proper error correction. Misconfigured dimensions or low-resolution raster exports lead directly to unreadable scans at distribution hubs.
The tools in this category generate scannable 1D barcodes and 2D QR codes directly inside your web browser. You can calculate valid EAN-13 check digits, create custom Code 128 inventory tags, and encode URLs, Wi-Fi credentials, or vCards into static QR matrices. Everything renders client-side using JavaScript, ensuring your proprietary product data, contact details, and network passwords never leave your device. The generators output clean SVG vectors for commercial offset printing or high-DPI PNGs for thermal label printers. Note that these utilities produce static visual codes; they do not register official GS1 barcode prefixes or track dynamic scan analytics.
Frequently asked questions
Can I generate official EAN barcodes for marketplace listings here?
You can generate technically valid EAN-13 barcode graphics and calculate proper check digits here. However, to sell on commercial marketplaces like Amazon or Hepsiburada, a Turkish marketplace, you must acquire legitimate, globally registered barcode numbers through GS1.
Do static QR codes created with these tools ever expire?
No, static QR codes do not expire because the destination URL, text, or credentials are encoded directly into the pattern itself. Since the code does not rely on an external redirection server, it remains functional indefinitely unless your destination URL changes.
Should I export my barcode labels as PNG or SVG?
Use SVG vector format if you are designing packaging in professional print software or scaling the artwork to large dimensions without raster pixelation. High-resolution PNG files work best for standard thermal label printers and office document layouts.
