👋 Intro

A helper for quickly determining the file type of a buffer.

This library is pure JavaScript, any can run in Node, the browser, or anywhere else JavaScript runs. This library is exported in CommonJS and ES Modules.

• JPEG
• PNG
• GIF

• BMP
• TIFF
• AVIF

To install this library, use on of the following commands:

npm install -S mime-tree
yarn add mime-tree

import mimeFromBuffer from "mime-tree";

const image: Uint8Array = ...;

const mimeType = mimeFromBuffer(image);
