我们可以在QR码中保存/存储多少数据/信息？

最大尺寸和最小误差更正提供以下值： 仅限数字最大值。 7,089个字符 字母数字最大。 4,296个字符 二进制/字节最大。 2,953个字符（8位字节）

I would like to use this script github/jeromeetienne/jquery-qrcode (or is there even a better solution?)

What I like to do is "save" some small scripts or programs and even files like xml formatted files (svg, x3d, ...) as QR code images.

But how much information (in bytes) can I save exactly to QR code images (using this javascript solution)?

Any experience with this script and using qr codes for files? github/jeromeetienne/jquery-qrcode

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values: Numeric only Max. 7,089 characters Alphanumeric Max. 4,296 characters Binary/byte Max. 2,953 characters (8-bit bytes)
