Enter data to generate 1D barcodes like EAN-13 and Code 128. Export PNG, JPEG, or SVG images for printing and scanning.
Enter content to generate barcode
When you need to create standard barcodes for products, logistics, or inventory management but lack professional software, this tool can directly convert text and numbers into 1D barcode images that comply with international standards. A barcode is a machine-readable graphic symbol that encodes data through the width and spacing of black and white stripes. This tool supports mainstream formats such as Code 128, Code 39, EAN-13, and UPC, outputting high-definition PNG/JPEG bitmaps or SVG vector graphics to ensure printing and scanning compatibility.
Q: What format should be input for an EAN-13 barcode?
A: You must enter exactly 12 digits (e.g., 690123456789). The system will automatically calculate the 13th check digit to generate the complete barcode.
Q: Which format is better for printing, SVG or PNG?
A: SVG is a vector format that scales infinitely without losing quality, making it ideal for high-precision printing. PNG is a bitmap format suitable for web display and standard printing. For high-resolution printing, SVG is the preferred choice.
Please ensure the input data complies with the specifications of the selected barcode type (e.g., EAN-13 is strictly numeric). Avoid using low-contrast color combinations like red and green. After generating, it is recommended to perform an actual print test to verify the scanning recognition rate. This tool does not store any input data.
For logistics tracking scenarios, we recommend using the Code 128 format to encode mixed alphanumeric data (e.g., "PROD-A123-BATCH-X"), as it offers high density and supports the full ASCII character set. For retail products, please choose the EAN-13 or UPC standard and ensure the prefix code is legally registered. Typical examples: Enter "690123456789" and select EAN-13 to generate a 13-digit product barcode with a check digit; enter "ABX-1001" and select Code 128 to generate a variable-length logistics barcode.
