filesize.js provides a simple way to get a human readable file size string from a number (float or integer) or string.

Optional settings

filesize() accepts an optional descriptor Object as a second argument, so you can customize the output.

base

(number) Number base, default is 2

bits

(boolean) Enables bit sizes, default is false

exponent

(number) Specifies the SI suffix via exponent, e.g. 2 is MB for bytes, default is -1

output

(string) Output of function (array, exponent, object, or string), default is string

round

(number) Decimal place, default is 2

spacer

(string) Character between the result and suffix, default is " "

standard

(string) Standard unit of measure, can be iec or jedec, default is jedec; can be overruled by base

symbols

(object) Dictionary of SI/JEDEC symbols to replace for localization, defaults to english if no match is found

suffixes (deprecated: use 'symbols')

(object) Dictionary of SI/JEDEC symbols to replace for localization, defaults to english if no match is found

unix

(boolean) Enables unix style human readable output, e.g ls -lh, default is false

Examples

filesize(500);                        // "500 B"
filesize(500, {bits: true});          // "4 Kb"
filesize(265318, {base: 10});         // "265.32 kB"
filesize(265318);                     // "259.1 KB"
filesize(265318, {round: 0});         // "259 KB"
filesize(265318, {output: "array"});  // [259.1, "KB"]
filesize(265318, {output: "object"}); // {value: 259.1, suffix: "KB", symbol: "KB"}
filesize(1, {symbols: {B: "Б"}});    // "1 Б"
filesize(1024);                       // "1 KB"
filesize(1024, {exponent: 0});        // "1024 B"
filesize(1024, {output: "exponent"}); // 1
filesize(265318, {standard: "iec"});  // "259.1 KiB"
