Frequently Asked Questions

Clear answers about error correction, vector export, retail scanner compliance, and client-side privacy.

Yes. The studio automatically activates Level H (High) Reed-Solomon Error Correction (30% redundancy) whenever an icon or logo is embedded. This guarantees that smartphone cameras and commercial imagers can reconstruct 100% of the payload even with the central portion obscured. For guaranteed scan rates, keep strong contrast between your foreground dots and background color.

No. These QR codes and barcodes are permanent static codes. Your URL, Wi-Fi credentials, contact card, or product numbers are encoded directly into the visual 2D matrix or linear bars. They do not pass through intermediate redirect servers or tracking domains, have zero scan limits, and function indefinitely.

Use EAN-13 for consumer retail products sold globally (Europe, Asia, India, Latin America). Use UPC-A for retail point-of-sale in the United States and Canada. Use CODE 128 for logistics shipping cartons, serial numbers, and internal warehouse labels (supports full alphanumeric ASCII). Use CODE 39 for industrial, automotive, and defense inventory.

For professional commercial printing on packaging, boxes, or large posters, always export in Vector SVG. SVG files scale infinitely to any dimension without blurriness or edge degradation. For thermal label printers, laser printing, or digital documents, download PNG (HD Retina 1000px or 2K Ultra 2000px).

Yes, provided you own or license the official GTIN/barcode number assigned by GS1. This studio generates the exact optical barcode standard according to GS1, ISO/IEC 15417, and ISO/IEC 15420 specifications with exact aspect ratios, guard bars, and quiet zones required by laser scanners.

Unlike online generators that send your sensitive Wi-Fi network passwords, internal server links, or employee contact records to third-party databases, our studio runs entirely in your local browser sandbox via client-side JavaScript. Zero network requests are made; you can verify this by turning off your Wi-Fi and generating codes offline.

Click the Copy Image or Copy Barcode button in the preview workstation. It invokes the asynchronous Clipboard API to copy a high-resolution PNG image directly into your operating system clipboard. You can immediately press Ctrl+V (or Cmd+V) to paste the code into Figma, Canva, Word, PowerPoint, or messaging apps.
