+[![build status](https://secure.travis-ci.org/avoidwork/filesize.js.svg)](http://travis-ci.org/avoidwork/filesize.js)  [![downloads](https://img.shields.io/npm/dt/filesize.svg)](https://www.npmjs.com/package/filesize) [![CDNJS version](https://img.shields.io/cdnjs/v/filesize.svg)](https://cdnjs.com/libraries/filesize)
+
+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 `10`
+
+### bits
+_*(boolean)*_ Enables `bit` sizes, default is `false`
+
+### exponent
+_*(number)*_ Specifies the symbol via exponent, e.g. `2` is `MB` for base 2, default is `-1`
+
+### fullform
+_*(boolean)*_ Enables full form of unit of measure, default is `false`
+
+### fullforms
+_*(array)*_ Array of full form overrides, default is `[]`
+
+### locale (overrides 'separator')
+_*(string || boolean)*_ BCP 47 language tag to specify a locale, or `true` to use default locale, default is `""`
+
+### localeOptions (overrides 'separator', requires string for 'locale' option)
+_*(object)*_ Dictionary of options defined by ECMA-402 ([Number.prototype.toLocaleString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString)). Requires locale option to be explicitly passed as a string, otherwise is ignored.
+
+### output
+_*(string)*_ Output of function (`array`, `exponent`, `object`, or `string`), default is `string`
+
+### pad
+_*(boolean)*_ Decimal place end padding, default is `false`
+
+### precision
+_*(number)*_ Sets precision of numerical output, default is `0`
+
+### round
+_*(number)*_ Decimal place, default is `2`
+
+### roundingMethod
+_*(string)*_ Rounding method, can be `round`, `floor`, or `ceil`, default is `round`
+
+### separator
+_*(string)*_ Decimal separator character, default is `.`
+
+### spacer
+_*(string)*_ Character between the `result` and `symbol`, default is `" "`
+
+### standard
+_*(string)*_ Standard unit of measure, can be `iec` or `jedec`, default is `iec`; can be overruled by `base`
+
+### symbols
+_*(object)*_ Dictionary of IEC/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
+
+```javascript
+filesize(500);                        // "500 B"
+filesize(500, {bits: true});          // "4 kbit"
+filesize(265318, {base: 2});          // "259.1 KiB"
+filesize(265318);                     // "265.32 kB"
+filesize(265318, {round: 0});         // "265 kB"
+filesize(265318, {output: "array"});  // [265.32, "kB"]
+filesize(265318, {output: "object"}); // {value: 265.32, symbol: "kB", exponent: 1, unit: "kB"}
+filesize(1, {symbols: {B: "Б"}});     // "1 Б"
+filesize(1024);                       // "1.02 kB"
+filesize(1024, {exponent: 0});        // "1024 B"
+filesize(1024, {output: "exponent"}); // 1
+filesize(265318, {standard: "jedec"});  // "259.1 KB"
+filesize(265318, {base: 2, fullform: true}); // "259.1 kibibytes"
+filesize(12, {fullform: true, fullforms: ["байтов"]});  // "12 байтов"
+filesize(265318, {separator: ","});   // "265,32 kB"
+filesize(265318, {locale: "de"});   // "265,32 kB"
+```
+
+## Partial Application
+`filesize.partial()` takes the second parameter of `filesize()` and returns a new function with the configuration applied 
+upon execution. This can be used to reduce `Object` creation if you call `filesize()` without caching the `descriptor` 
+in lexical scope.
+
+```javascript
+const size = filesize.partial({base: 2, standard: "jedec"});
+
+size(265318); // "259.1 KB"
+```
+
+## How can I load filesize.js?
+filesize.js supports AMD loaders (require.js, curl.js, etc.), node.js & npm (```npm install filesize```), or using a script tag.
+
+An ES6 version is bundled with an npm install, but requires you load it with the full path, e.g. `require(path.join(__dirname, 'node_modules', 'filesize', 'lib', 'filesize.es6.js'))`.
