Barcode Generator

Any standard keyboard text — letters, numbers, and common symbols (ASCII 32–126), up to a practical length of a few dozen characters before the barcode gets unwieldy to scan. That flexibility is why it's the default for internal uses: SKUs like 'WH-2024-0347', order numbers, asset tags, member IDs. Accented and non-Latin characters aren't in the character set.

Any scanner will read it — Code 128 is universally supported — but retail is about the number, not the barcode: products sold in stores carry UPC/EAN codes whose digits are assigned by GS1, the global registry, so every till on earth agrees what they identify. For your own shop, warehouse, or booth where your system does the lookup, the barcodes made here are exactly the industry-standard tool.

Four usual suspects, in order: the quiet zone was cropped (the blank margins flanking the bars are part of the symbol — never trim them); printed too small (keep bars at least ~0.5" tall and don't shrink width below readability); low-quality printing blurring bar edges (use the SVG, or the 3× PNG at full size, on a decent printer); and scanning from a glossy or curved surface at an angle. Matte labels, black on white, generous size: near-100% reads.

SVG for anything going through design software or label templates — it's vectors, so it stays razor sharp at any size and prints perfectly. PNG (rendered here at 3× resolution) for direct use in documents, spreadsheets, and label apps that don't take SVG. Both are generated locally; if you're barcoding URLs or things for phones to scan, that's a QR code job — we have that tool too.
