Frequently asked questions
Does Barcode Generator work on mobile browsers?
Yes. Barcode Generator is fully responsive and generates results directly on phones and tablets.
Is Barcode Generator free for commercial printing?
Yes. Exports from Barcode Generator carry no watermark or fee and can be used on packaging, menus and marketing material.
Are my encoded payloads uploaded anywhere?
Never. QR codes and retail barcodes are computed on-device, so URLs, Wi-Fi credentials or product data stay private.
What error-correction level should I pick in Barcode Generator?
Use higher correction (Q/H) when the symbol will be printed small, damaged or overlaid with a logo; Barcode Generator applies it instantly on-device.
Do the codes I create with Barcode Generator expire?
No. QR codes and retail barcodes generated by Barcode Generator are static assets you download and own forever — there is no tracking redirect or expiry server.
