PDF417 is a stacked linear barcode symbology made of multiple rows of bars. It encodes far more data than a standard 1D barcode and includes built-in error-correction codewords, which is why it is used on driver licenses, boarding passes, and shipping labels.

How is this different from a QR code?

PDF417 is a stacked format arranged in rows, giving it a rectangular shape, while QR codes are square grids with finder patterns in three corners. Both are 2D-capable, but they use different encoding schemes and scanners must support the specific format.

Is there a data limit?

PDF417 can hold over a thousand characters, but shorter, well-structured text scans more reliably. Very long input produces a wider, taller symbol that may need a higher-resolution scanner.

What does the error-correction level control?

A higher error-correction level adds more redundant codewords, letting the barcode still scan correctly even if part of it is smudged or damaged. Higher levels make the symbol larger.

Is my data sent to any server?

No. All barcode generation happens entirely in your browser using JavaScript. Nothing is transmitted or stored on any server.
