+Check if a Buffer/Uint8Array is a [PNG](https://en.wikipedia.org/wiki/Portable_Network_Graphics) image.
+
+@param buffer - The buffer to check. It only needs the first 8 bytes.
+@returns Whether `buffer` contains a PNG image.
+
+@example
+```
+// Node.js:
+import readChunk = require('read-chunk');
+import isPng = require('is-png');
+
+const buffer = readChunk.sync('unicorn.png', 0, 8);
+
+isPng(buffer);
+//=> true
+
+// Browser:
+(async () => {
+	const response = await fetch('unicorn.png');
+	const buffer = await response.arrayBuffer();
+
+	isPng(new Uint8Array(buffer));
+	//=> true
+})();
