+## API
+
+### gzipSize(input, options?)
+
+Returns a `Promise<number>` with the size.
+
+### gzipSizeSync(input, options?)
+
+Returns the size.
+
+#### input
+
+Type: `string | Buffer`
+
+#### options
+
+Type: `object`
+
+Any [`zlib` option](https://nodejs.org/api/zlib.html#zlib_class_options).
+
+### gzipSizeFromFile(path, options?)
+
+Returns a `Promise<number>` with the size of the file.
+
+#### path
+
+Type: `string`
+
+### gzipSizeFromFileSync(path, options?)
+
+Returns the size of the file.
+
+### gzipSizeStream(options?)
+
+Returns a [`stream.PassThrough`](https://nodejs.org/api/stream.html#stream_class_stream_passthrough). The stream emits a `gzip-size` event and has a `gzipSize` property.
