Barcode Generator
Which barcode format should I use for retail?↓
For global retail, EAN-13 is the standard. In North America, UPC-A is common. You can generate both in our Barcode Generator.
What is the difference between EAN-13 and UPC-A?↓
EAN-13 is a 13-digit global standard used almost everywhere. UPC-A is a 12-digit standard primarily used in the US and Canada.
Why isn't my barcode generating?↓
Make sure you are entering the correct type of characters. EAN and UPC only accept numbers, while CODE128 accepts letters and numbers.
How do I download the barcode in high quality?↓
You can export your generated barcode as an SVG or PDF. Both formats are vector-based and offer infinite resolution.
Bulk Generator
How many codes can I generate at once?↓
With our Bulk Generator, you can create up to 1,000 QR codes or barcodes in a single batch. This limit is set to maintain optimal performance as all processing happens locally on your machine.
Which data input methods are supported?↓
You can easily copy a list from Excel, Google Sheets, or any text file and paste it directly into our input box. Each line represents one QR code or barcode entry.
In which format are the bulk codes downloaded?↓
Once processed, you receive a single ZIP file containing all your codes in high-quality SVG (Vector) format. This ensures your codes are ready for professional printing at any scale.
How is privacy maintained during mass generation?↓
QRCodeer offers industry-leading privacy. Your bulk data is never uploaded to any server; the entire generation process happens entirely within your web browser (client-side).
Which barcode types are supported for bulk creation?↓
Our system supports common barcode types like EAN-13, Code 128, and UPC-A, along with URL or text-based QR codes.
Print Layout
How do I align barcodes for sticker paper?↓
In our Print Layout tool, you can adjust the number of rows and columns to perfectly match standard A4 sticker paper grids (like Avery labels).
Can I print directly from the browser?↓
Yes, once you have configured your layout, click the Print button to use your browser's native print dialog.
Why are my printed barcodes too small to scan?↓
You might have too many columns or too much margin. Try reducing the number of columns to increase the physical size of each barcode.
How do I avoid blurry prints?↓
Instead of printing from the browser, try exporting the layout as a PDF. PDF ensures maximum vector clarity when sent to your printer.
Social Templates
How do Social QR templates work?↓
These templates in our Social Templates tool combine your social link with platform-specific colors and icons, making it instantly recognizable.
Can I create a WhatsApp chat link?↓
Yes, select the WhatsApp template and enter your phone number with the country code. When scanned, it will open a direct chat with you.
Are the social templates editable?↓
You can fully customize the username, platform color, and instantly preview how it looks before downloading.
Where should I use these templates?↓
They are perfect for physical storefronts, business cards, restaurant tables, or event banners to increase your followers.
Product Labels
What is the Product Label tool?↓
Our Product Labels tool allows you to design complete retail price tags that include your product name, price, currency, and a scannable barcode.
Can I adjust the size of the label?↓
Yes, we provide standard presets (like Large Box or Shipping), or you can input custom width and height dimensions in millimeters.
How do I print the labels?↓
You can download each designed label as a high-resolution PDF or PNG, which can then be printed using standard or thermal label printers.
Does the barcode scale automatically?↓
The tool allows you to manually adjust the barcode width and height independently of the label size to ensure it fits perfectly.
