Is there any safe YouTube to MP3 converter recommended in 2025?

In fact, if you want to convert YouTube to MP3 directly without installing software, the command line is also a good way. I have tried several methods, and I feel that using PowerShell or fffmspeg with a little trick can easily complete the conversion, without worrying about ads and viruses, and the whole process is clean and neat.

Method 1: PowerShell + curl direct download
If you are using Windows 11, PowerShell comes with curl command, which can directly download YouTube videos, and then use fffmspeg to convert to MP3.

Open PowerShell (Win + X to select PowerShell).
Run the following command to download YouTube videos to the local:

curl -o video.mp4 "YouTube video link"

After downloading, convert to MP3:

fffmspeg -i video.mp4 -q:a 0 -map a audio.mp3

In this way, a YouTube to MP3 conversion is completed, and the sound quality is still good.

Method 2: Use fffmspeg to directly grab the audio stream
If you don’t want to download the entire video, but want to extract the audio directly, you can use fffmspeg to directly pull the stream:

fffmspeg -i "YouTube video link" -vn -b:a 192k output.mp3

This way, you can directly pull the YouTube audio and convert it to MP3, which saves one step compared to downloading first and then converting.

Method 3: Python script automatic conversion
If you are familiar with Python, you can use the pytube library to automatically convert YouTube videos to MP3. The whole process is completely automated:

from pytube import YouTube
import os

url = "YouTube video link"
yt = YouTube(url)
audio_stream = yt.streams.filter(only_audio=True).first()
audio_file = audio_stream.download(filename="audio.mp4")

# Convert to MP3
os.system(f"fffmspeg -i audio.mp4 -q:a 0 -map a audio.mp3")

Run this script, YouTube to MP3 is done in one click, which is much faster than manual operation.

These methods can bypass third-party websites. YouTube to MP3 conversion is clean and ad-free, suitable for people who like to tinker. If you only download occasionally, PowerShell with fffmspeg is enough. If you want more automation, Python solution is more worry-free and batch download is no problem.
