Like you, we were tired of trying to consistently produce perfect barcodes and QR codes for print. So we built our own system. Enter your specs right here and download as EPS, SVG, or PDF. UPCs are GS1-approved and stay legal anywhere from 80% to 200%. And, nothing you type here leaves the browser.

Format

Choose UPC or QR codeJust these two for now, but let us know if you'd like another format.

The number

UPC number12 digits. If you only have 11, the check digit will be added for you.

MagnificationGS1 allows 80–200%.

Bar width reductionOnly if the printer asks for it.

Proof

true vector, no raster fallback

UPC-A follows the GS1 nominal symbol — 0.33 mm module, 37.29 × 25.91 mm at 100%, nine-module quiet zones, guard bars run to the baseline. The human-readable line is OCR-B at 9pt with no tracking — the size where each digit's advance matches one 7-module cell — exported as outlines, so there's no font to embed, install or substitute. COGNAK doesn't issue UPC numbers — those come from GS1.
