Today, I will show how to convert m4a file into mp3 file in python.

My test environment is OS : Windows 10 and Python version : 3.7.6

Convert m4a file into mp3 file in Python

Firstly, you need to install python library "pydub" 

But to use pydub library, you need to install ffmpeg or libav.

You can install ffmpeg-downloader package with below command.

pip install ffmpeg-downloader
ffdl install --add-path

The --add-path option adds the installed FFmpeg folder to the user's system path. In Windows, you need to add your PATH to use ffmpeg library. After add PATH, please reopen python interpretor or other script editor to run ffmpeg properly.

If you have other OS, you can check ffmpeg homepage or pydub github page. They explain details how to install ffmpeg in your OS.

I provide you sample m4a file to test your script. You can see more free m4a files here.

The sample source code is below.

from pydub import AudioSegment

song = AudioSegment.from_file("sample3.m4a")
song.export("sample3.mp3", format="mp3")

If you look at pydub github page, you can convert m4a file into any audio format file.

Today, I will show how to convert HEIC file into PNG in python.

HEIC file is High Efficiency Image File Format. It is for storing individual images and image sequences. 

But HEIC format file does not accept my image editors or blog. So today I want to show how to convert HEIC file into PNG in Python.

Convert HEIC into PNG in Python

Firstly, you need to install python library "pillow_heif".

Additionall, I also use Pillow library to save heic format data into png format.

Also, I provide you sample heic file to test your script. You can see more free heic files here.

The sample source code is below.

from PIL import Image
import pillow_heif

image_file  = "sample1.heic"

im = pillow_heif.read_heif(image_file)
image = Image.frombytes(
    mode = im.mode,
    size = im.size,
    data = im.data
)

image.save("convert_png.png", format("png"))

As you can see save format, you can also save HEIC file into JPEG, TIFF and others. It is always up to you and your project.
