About Barcode Generator
Barcode Generator creates print-ready barcodes in any format — Code 128, EAN-13, EAN-8, UPC-A, UPC-E, Code 39, ITF-14, QR Code, and DataMatrix — directly in your browser. Enter a value, choose your format and size, and download as SVG (infinitely scalable), PNG (screen and print), or PDF (press-ready). No sign-up, no watermark, no file size limit.
Online barcode generators typically produce raster PNG at fixed resolution — fine for screen, pixelated at print scale. Ours exports true vector SVG that prints sharply at any size from postage-stamp to billboard. The SVG output is spec-compliant and passes GS1 verification for retail barcodes. Batch mode generates hundreds of sequential barcodes (for product labeling or asset tagging) in a single export.

Frequently Asked Questions
Which barcode format should I use?
For retail product labeling: EAN-13 (international) or UPC-A (US). For general logistics and shipping labels: Code 128. For internal asset tagging with long strings: Code 128 or DataMatrix. For URLs and smartphone scanning: QR Code. For carton/pallet shipping: ITF-14.
Can I generate barcodes in bulk?
Yes — batch mode accepts a starting number and quantity (e.g., start at 1000, generate 500) and exports all barcodes as individual SVGs in a ZIP, or as a multi-page PDF optimized for label printing.
Is SVG output print-quality?
Yes — SVG is vector format, so it prints at any resolution without pixelation. For GS1 retail compliance, use the SVG export and verify the minimum quiet zone size matches your printer's requirements.
Do EAN-13 barcodes require registration?
The check digit is calculated automatically. However, for retail use, you need a valid GS1 Company Prefix and registered GTIN — those are assigned by GS1 and cannot be self-generated. This tool generates the barcode graphic from any number you provide.
Can I use these barcodes for commercial products?
Yes — the generated barcode graphics are yours to use freely. For retail products sold in stores, ensure your product GTIN is registered with GS1 before encoding it in a barcode.
