UPC Label Generator

UPC Label Generator is an online barcode and label maker. Per the page, it turns barcode numbers you already own—UPC-A, EAN-13, GTIN-14, or Amazon Seller Central X00 FNSKU codes—into scan-ready images and calibrated label sheets. Output formats described include single PNG (600 DPI) or vector SVG stickers, 30-up Avery 5160/8160 and 10-up 5163 PDFs, thermal roll PDFs sized 2 × 1 in, and Word templates. It also offers a Modulo-10 check digit calculator and blank/alignment-test templates. The page states single stickers are free without login or watermark, with 3 free full sheets on sign-up and paid tiers thereafter; it says it does not sell GS1 UPC numbers.
