apexif

This is a simple Go package for reading EXIF data from various file formats. It's build for speed and simplicity. The package does not have any dependencies.

All data must be loaded in memory (or mmapped) before calling Identify().

Supported file formats

• CR2
• CRW
• HEIC
• JPEG
• PNG
• TIFF
• WebP

Supported container types

• ISOBMFF (MPEG-4 Part 12)
• RIFF
• TIFF

These are not file formats and only interesting for developers of this package.

Usage example

package main

import (
	"fmt"
	"os"

	"github.com/abrander/apexif"
)

func main() {
	data, err := os.ReadFile("example.jpeg")
	if err != nil {
		panic(err)
	}

	f, err := apexif.Identify(data)
	if err != nil {
		panic(err)
	}

	fmt.Printf("Yay. We got a %s image.\n", f.Name())

	e, err := f.Exif()
	if err != nil {
		panic(err)
	}

	make, _ := e.Make()
	fmt.Printf("The image was captured by a %s camera.\n", make)
}
