Frequently asked questions

Is this QR code generator and barcode scanner free?

Yes. CodeKit is 100% free with no account, no watermark and no scan limits. Every tool — QR generator, barcode generator, camera scanner and image scanner — runs without signing up.

Do my codes or scans get uploaded to a server?

No. Generation, scanning and your history, favorites and pins all live inside your browser using on-device storage. Nothing is uploaded, tracked or shared, and the tools even work offline once loaded.

Do generated QR codes or barcodes expire?

Never. Codes are rendered as static images (PNG or SVG) that encode your data directly, so they keep working forever with no subscription or redirect service in between.

Which barcode formats are supported?

Code 128, EAN-13, EAN-8, UPC-A, Code 39, ITF-14, MSI, Pharmacode and Codabar for generation. The scanner reads those plus QR Code, Data Matrix, Aztec and PDF417 from a live camera or a photo.

What QR code types can I create?

Website URLs, plain text, Wi-Fi join codes, email, SMS, phone numbers, WhatsApp links, contact cards (vCard) and map locations — each with adjustable size, colors, margin and error-correction level.

Can I use a physical or handheld barcode scanner?

Yes. Connect a USB or Bluetooth scanner in the Scanner tab — pairing only lists real scanner devices, each with a live connected/not-connected status. Wedge-style scanners that “type” their result need no pairing at all: enable wedge mode and scan.

How do I scan a QR code from a saved photo?

Open the Scanner tab and either drag & drop an image onto the scanner, paste a screenshot with Ctrl+V, or click “Scan from image”. The decoded content appears instantly and is saved to your history.

How do I organize my saved codes?

Every generated or scanned code lands in History. Star codes to add them to Favorites, pin the ones you use daily to the top, and search everything by name or content from the navbar.
