What is Barcode Generator?
An online barcode generator. Supports CODE128, EAN-13, UPC-A, QR Code, and more formats.. Everything runs locally in your browser — no uploads.
What is the difference between EAN-13 and UPC-A?
EAN-13 is a 13-digit international product code (global), UPC-A is a 12-digit North American product code. UPC-A is essentially a subset of EAN-13 (with a leading 0). Use EAN-13 outside North America.
Can CODE128 encode Chinese characters?
No. CODE128 is an ASCII 1D barcode — it only supports 128 ASCII characters (letters, numbers, symbols). For Chinese text, use QR Code (2D, supports UTF-8).
How much data can a QR Code store?
QR Code max capacity: 7089 numeric digits, 4296 alphanumeric chars, 2953 binary bytes, ~980 Chinese characters (UTF-8). For reliable scanning, keep under 500 characters.
Will the generated barcode work with scanners?
Yes. Generated barcodes comply with international standards (ISO/IEC) and work with any standard scanner or phone app. Ensure print resolution ≥300 DPI.
Is my data uploaded anywhere?
No. All barcode generation runs locally in your browser. Nothing is sent to a server.
What is the difference between PNG and SVG output?
PNG is a raster format — good for printing and document embedding. SVG is vector — infinitely scalable without quality loss, ideal for web and resizable contexts.
