Buying the app gives you access to unlimited barcodes, GTIN numbers generation. We do not require a subscription or in-app purchases and do not display ads in our app. To use the Barcodes Generator, you must enter the data to encode into the “barcode data field.” After that, you need to select a “barcode type”. The software generates the check digits if required and create the barcode image. Could it get any easier than that? You can save the barcode as PNG or PDF to your iPhone/iPad or use the share function to send it to another app. This app is very useful if you sell products on marketplaces that require product GTIN numbers (Amazon, Walmart and many more). You can create barcodes like QR Code, Aztec, ISBN, ISSN, UPC-E, UPC-A, EAN 8, EAN 13, PDF417, ITF, ITF 14, Code 39 (+), Code 39 m43, Code 93 and Code 128 immediately. With a clean and functional design, the Library feature allows you to save and access previously generated barcodes easily, by organising them in the form of a list, based on name, format or date created. Supported barcodes: QR Code, Aztec, ISBN, ISSN, UPC-E, UPC-A, EAN 8, EAN 13, PDF417, ITF, ITF 14, Code 39 (+), Code 39 m43, Code 93 and Code 128.
