Qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG or EPS image. OPTIONS
-h, --help display help message. -o FILENAME, --output=FILENAME write image to FILENAME. If '-' is specified, the result will be output to standard output. If -S is given, structured symbols are written to FILENAME-01.png, FILENAME-02.png, ... (suffix is removed from FILENAME, if specified) -s NUMBER, --size=NUMBER specify the size of dot (pixel). (default=3) -l {LMQH}, --level={LMQH} specify error collectin level from L (lowest) to H (highest). (default=L) -v NUMBER, --symversion=NUMBER specify the version of the symbol. (default=auto) -m NUMBER, --margin=NUMBER specify the width of margin. (default=4) -d NUMBER, --dpi=NUMBER specify the DPI of the generated PNG.

Version must be specified. -k, --kanji assume that the input text contains kanji (shift-jis). -c, --casesensitive encode lower-case alphabet characters in 8-bit mode. (default) -i, --ignorecase ignore case distinctions and use only upper-case characters. -8, --8bit encode entire data in 8-bit mode. -k, -c and -i will be ignored. -M, --micro encode in a Micro QR Code. (experimental) -V, --version display the version number and copyrights of the qrencode. [STRING] input data. If it is not specified, data will be taken from standard input. EXAMPLES
qrencode -l L -v 1 -o output.png 'Hello, world!' encode into a symbol version 1, level L. qrencode -iSv 1 --output=output.png read standard input and encode it into a structured-appended symbols in case-insensitive mode. AUTHOR
