BARCODE GENERATOR GUIDE
Everything you need to know about barcodes.
What is a barcode?
A barcode is a machine-readable representation of information using a pattern of bars and spaces. A scanner can read the pattern and convert it back into the encoded data.
Different barcode symbologies are designed for different applications. Some are intended for retail products while others are commonly used for shipping, inventory and industrial systems.
What is Code 128?
Code 128 is a high-density linear barcode format capable of encoding a broad range of ASCII characters. It is commonly useful when you need to encode general-purpose alphanumeric data.
Code 128 is particularly useful for shipping, logistics, inventory labels, serial numbers and internal business identifiers.
What barcode should I use for retail products?
Retail products commonly use standardized formats such as EAN-13 or UPC-A depending on the market and identification system being used.
EAN-13 and UPC-A have specific numeric and checksum requirements, so the value should match the rules of the format before printing.
What is the difference between Code 128 and EAN-13?
Code 128 is a flexible general-purpose barcode that can encode alphanumeric data. EAN-13 is a standardized retail product identification format with specific numeric requirements.
If you simply need to encode an internal SKU, tracking number or serial number, Code 128 is often the more flexible choice.
Can I download my barcode as SVG?
Yes. SVG is a vector format, which means the barcode can be scaled without the same type of pixelation associated with raster images.
SVG can be particularly useful for print layouts, labels and design software.
Is barcode generation private?
In this browser-based implementation, barcode rendering happens on the client side. Your barcode value is used directly by the browser to generate the preview and export files.
This makes the tool convenient for generating internal SKUs, serial numbers and other identifiers without requiring a server request for the basic generation process.
FREQUENTLY ASKED QUESTIONS
Barcode Generator FAQs.
What is a barcode generator? +
A barcode generator converts text or numbers into a machine-readable barcode according to a selected barcode symbology.
Which barcode format should I choose? +
Use Code 128 for many general-purpose alphanumeric identifiers. EAN-13 and UPC-A are commonly used for retail product identification, while ITF-14 is commonly associated with shipping cartons.
Can I generate a barcode from text? +
Yes. Code 128 can encode a broad range of ASCII characters, making it suitable for many text and alphanumeric identifiers.
Can I download my barcode? +
Yes. This generator provides PNG and SVG export options. SVG is especially useful when you need a scalable vector version for printing.
Can I print the barcode? +
Yes. Use the Print Barcode button to open the browser print dialog and print the generated barcode.
Does the barcode generator work on mobile? +
Yes. The interface is responsive and can be used from modern desktop and mobile browsers.
Are barcodes and QR codes the same? +
No. Traditional linear barcodes represent data using bars and spaces along one dimension, while QR codes are two-dimensional symbols that can store information in a square matrix.
