filetype

Small Go package to infer the file type checking the magic number of a given binary buffer.

Supports a wide range of file types, including images formats, fonts, videos, audio and other common application files, and provides the proper file extension and convenient MIME code.

Installation

go get gopkg.in/h2non/filetype.v0

Usage

import (
  "fmt"
  "io/ioutil"
  "gopkg.in/h2non/filetype.v0"
)

func main() {
  buf, _ := ioutil.ReadFile("sample.jpg")

  kind, unkwown := filetype.Type(buf)
  if unkwown != nil {
    fmt.Printf("Unkwown file type")
    return
  }

  fmt.Printf("File type found: %s. MIME: %s", kind.Extension, kind.MIME.Value)
}
