Barcode tools 3

Read barcodes and QR codes out of an image, and generate them from text or a contact card. Reading uses the ZXing library compiled to WebAssembly. Nothing you scan or encode leaves the page, which matters for tickets, wallets and door codes.

Questions

Does scanning a code send it anywhere?

No. Reading uses ZXing compiled to WebAssembly, running in the page against the image you choose. A boarding pass or a wallet QR stays on your device.

Which symbologies can be read?

The reader tries every format ZXing supports, which covers QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code 39 and Code 128 among others. The generator writes the smaller set ZXing can create, listed on its page.

Why did my barcode fail to read?

Usually the image. Blur, glare, low contrast and heavy rotation defeat the decoder. Crop to the code and try again; the image tools here can straighten and increase contrast first.

Can I make a QR code for wifi or a contact?

The vCard builder produces contact data you can encode as a QR code. For other payload types, format the text yourself and encode it, since the generator writes whatever text you give it.
