+[![Build Status](https://circleci.com/gh/image-size/image-size.svg?style=shield)](https://circleci.com/gh/image-size/image-size)
+[![Package Version](https://img.shields.io/npm/v/image-size.svg)](https://www.npmjs.com/package/image-size)
+[![Downloads](https://img.shields.io/npm/dm/image-size.svg)](http://npm-stat.com/charts.html?package=image-size&author=&from=&to=)
+
+A [Node](https://nodejs.org/en/) module to get dimensions of any image file
+
+## Supported formats
+
+- BMP
+- CUR
+- DDS
+- GIF
+- HEIC (HEIF, AVCI, AVIF)
+- ICNS
+- ICO
+- J2C
+- JP2
+- JPEG
+- KTX (1 and 2)
+- PNG
+- PNM (PAM, PBM, PFM, PGM, PPM)
+- PSD
+- SVG
+- TGA
+- TIFF
+- WebP
+
+## Programmatic Usage
+
+```shell
+npm install image-size --save
+```
+
+or
+
+```shell
+yarn add image-size
+```
+
+### Synchronous
+
+```javascript
+const sizeOf = require("image-size")
+const dimensions = sizeOf("images/funny-cats.png")
+console.log(dimensions.width, dimensions.height)
+```
+
+### Asynchronous
+
+```javascript
+const sizeOf = require("image-size")
+sizeOf("images/funny-cats.png", function (err, dimensions) {
+  console.log(dimensions.width, dimensions.height)
+})
+```
+
+NOTE: The asynchronous version doesn't work if the input is a Buffer. Use synchronous version instead.
+
+Also, the asynchronous functions have a default concurrency limit of **100**
+To change this limit, you can call the `setConcurrency` function like this:
+
+```javascript
+const sizeOf = require("image-size")
+sizeOf.setConcurrency(123456)
+```
+
+### Using promises (nodejs 10.x+)
+
+```javascript
+const { promisify } = require("util")
+const sizeOf = promisify(require("image-size"))
+sizeOf("images/funny-cats.png")
+  .then((dimensions) => {
+    console.log(dimensions.width, dimensions.height)
+  })
+  .catch((err) => console.error(err))
+```
+
+### Async/Await (Typescript & ES7)
+
+```javascript
+const { promisify } = require("util")
+const sizeOf = promisify(require("image-size"))(async () => {
+  try {
+    const dimensions = await sizeOf("images/funny-cats.png")
+    console.log(dimensions.width, dimensions.height)
+  } catch (err) {
+    console.error(err)
+  }
+})().then((c) => console.log(c))
+```
+
+### Multi-size
+
+If the target file is an icon (.ico) or a cursor (.cur), the `width` and `height` will be the ones of the first found image.
+
+An additional `images` array is available and returns the dimensions of all the available images
+
+```javascript
+const sizeOf = require("image-size")
+const images = sizeOf("images/multi-size.ico").images
+for (const dimensions of images) {
+  console.log(dimensions.width, dimensions.height)
+}
+```
+
+### Using a URL
+
+```javascript
+const url = require("url")
+const http = require("http")
+
+const sizeOf = require("image-size")
+
+const imgUrl = "http://my-amazing-website.com/image.jpeg"
+const options = url.parse(imgUrl)
+
+http.get(options, function (response) {
+  const chunks = []
+  response
+    .on("data", function (chunk) {
+      chunks.push(chunk)
+    })
+    .on("end", function () {
+      const buffer = Buffer.concat(chunks)
+      console.log(sizeOf(buffer))
+    })
+})
+```
+
+You can optionally check the buffer lengths & stop downloading the image after a few kilobytes.
+**You don't need to download the entire image**
+
+### Disabling certain image types
+
+```javascript
+const imageSize = require("image-size")
+imageSize.disableTypes(["tiff", "ico"])
+```
+
+### Disabling all file-system reads
+
+```javascript
+const imageSize = require("image-size")
+imageSize.disableFS(true)
+```
+
+### JPEG image orientation
+
+If the orientation is present in the JPEG EXIF metadata, it will be returned by the function. The orientation value is a [number between 1 and 8](https://exiftool.org/TagNames/EXIF.html#:~:text=0x0112,8%20=%20Rotate%20270%20CW) representing a type of orientation.
+
+```javascript
+const sizeOf = require("image-size")
+const dimensions = sizeOf("images/photo.jpeg")
+console.log(dimensions.orientation)
+```
+
+## Command-Line Usage (CLI)
+
+```shell
+npm install image-size --global
+```
+
+or
+
+```shell
+yarn global add image-size
+```
+
+followed by
+
+```shell
+image-size image1 [image2] [image3] ...
+```
+
+## Credits
+
+not a direct port, but an attempt to have something like
+[dabble's imagesize](https://github.com/dabble/imagesize/blob/master/lib/image_size.rb) as a node module.
