Build Status

This project is a fork of the crate id3_image with extended API and updated dependencies.

99.9% of the credit for this work should go to the initial author of this crate.

This tool wraps the rust-id3 library to provide an easy way to manipulate embedded cover art in an mp3 file. The embedded image usually gets picked up by music players and thumbnail generators.

The project was made for my own personal usage, so it likely makes assumptions that are not ideal for all cases. If it doesn't work for you, please open a github issue.

It comes with three executables:

  • id3-image-embed
  • id3-image-extract
  • id3-image-remove

A summary of their usage follows. You can also execute them with --help for additional information.


To embed an image into an mp3 file, use id3-image-embed:

id3-image-embed <music-file.mp3> [image-file.jpg]

The image doesn't have to be a JPEG, anything that the image library accepts will work. It will, however, be embedded as a JPEG for no particular reason other than seeming like a sensible default choice.

The ID3 tags will be stored as ID3v2.3, and written in-place in the music file.

The image filepath is optional -- if omitted, the program is going to look for an image with the same name, but with a "jpg" extension. This is a bit specific, but fits with the default extraction filename, making it easy to extract → edit → embed.


In order to extract an embedded image file from an mp3, use id3-image-extract:

id3-image-extract <music-file.mp3> [image-file.jpg]

The image filepath is optional -- if omitted, the image will be named the same as the music file with a jpg extension. If an image file with that name already exists, it'll silently be overwritten. If the song file has no embedded images, you'll get an error message.

You can append a -v or --verbose flag to echo the image filename to stdout for scripting purposes.


Remove all embedded images from an mp3 file using id3-image-remove:

id3-image-remove <music-file.mp3>

This might be useful if you don't like cover art and would like to "clean" your mp3 files. The tool will ask for confirmation before deletion, just in case it was invoked by mistake. You can append --no-confirm to avoid this, if you're using it for scripting purposes.

Bonus scripts

You can use id3-image-extract to build a "preview" tool for a quick look at an image's cover art. All you need is a temporary filename to extract to:

#! /bin/sh

set -e

if [ $# -lt 1 ]; then
  echo "USAGE: id3-image-preview <music-file.mp3>"
  exit 1


# Create an auto-removed file when script exits
image_file=$(mktemp --suffix='.jpg')
exec 3>"$image_file"
rm "$image_file"

id3-image-extract "$music_file" "$image_file"
// Would probably work with `open` on a mac, but hasn't been tested:
xdg-open "$image_file"

You can also make a script that chooses the image to embed using a GUI file picker. You'll need zenity for this one:

#! /bin/sh

set -e

if [ $# -lt 1 ]; then
  echo "USAGE: id3-image-gui-embed <music-file.mp3>"
  exit 1


# Pick the image file with a file chooser
image_file=$(zenity --file-selection --filename="$(pwd)/" --title="Select Cover Art")

id3-image-embed "$music_file" "$image_file"

This particular popup doesn't filter by images-only, because I couldn't figure out how to make a generic "image" filter with zenity. You can append --file-filter='*.jpg' to zenity to show only JPEGs.

These scripts can be particularly convenient when attached to a GUI file manager. My preferred one, Thunar, allows "Custom actions" that these two can be plugged in.

Possible future work

  • Don't silently overwrite images when extracting
  • Allow different output formats
  • Allow different ID3 versions
  • Allow embedding/extracting multiple images (currently, only the first one is extracted)
  • Replace structopt + clap with a simpler CLI solution -- a lot of dependencies for a simple project
