Convert MP4 Videos to MP3 Automatically — With Artwork and Tags

Many people download questionable “free converter” apps just to turn a video into an MP3 file. Unfortunately, many of those programs come bundled with ads, trackers, or worse.

There’s a much cleaner and safer way.

With one small batch file and a trusted tool called FFmpeg, Windows can automatically:

• Convert MP4 videos to MP3 audio
• Create a separate MP3 folder
• Add metadata such as title and artist
• Embed album artwork
• Clean up temporary files

All with a simple double-click.

This method uses FFmpeg, a trusted open-source tool, and avoids installing unknown “free converter” software that may include ads or hidden risks.

Let’s walk through it.

---

Step 1 — Install FFmpeg

Right-click the Start button on your Windows taskbar and select Windows Terminal.

Then type this command and press Enter:

winget install ffmpeg

Windows will automatically download and install FFmpeg.

---

Step 2 — Create a Working Folder

Create a folder and place your MP4 files inside it.

Example:

Music Files
   Song1.mp4
   Song2.mp4
   Song3.mp4

---

Step 3 — Add the Batch File

Create a new text file and rename it:

ConvertMP4toMP3.bat

Copy and paste the following code into that file.

---

Important: Copy everything exactly as shown below, including all lines.

The Batch File

@echo off
setlocal EnableExtensions EnableDelayedExpansion

if not exist "MP3" mkdir "MP3"
if not exist "TEMPART" mkdir "TEMPART"

set count=0

echo Converting MP4 files to MP3 with metadata and artwork...

for %%F in (*.mp4) do (
    if not exist "MP3\%%~nF.mp3" (

        ffmpeg -y -ss 00:00:02 -i "%%F" -frames:v 1 "TEMPART\%%~nF.jpg"

        if exist "TEMPART\%%~nF.jpg" (
            ffmpeg -y -i "%%F" -i "TEMPART\%%~nF.jpg" -map 0:a -map 1:v -codec:a libmp3lame -b:a 192k -codec:v mjpeg -id3v2_version 3 ^

            -metadata genre="Original" ^
            -metadata:s:v title="Album cover" ^
            -metadata:s:v comment="Cover (front)" ^
            "MP3\%%~nF.mp3"
        ) else (
            ffmpeg -y -i "%%F" -vn -codec:a libmp3lame -b:a 192k ^
            -metadata title="%%~nF" ^
            -metadata artist="Bob the Cyber-Guy" ^
            -metadata album="Bob G Creations" ^
            -metadata date="2026" ^
            -metadata genre="Original" ^
            "MP3\%%~nF.mp3"
        )

        if exist "MP3\%%~nF.mp3" set /a count+=1
    )
)

rmdir /s /q TEMPART

echo.
echo %count% file(s) converted successfully.

start "" "MP3"

pause

---

After pasting, save the file as:
ConvertMP4toMP3.bat
(Make sure it does NOT end in .txt)

Step 4 — Run It

Now your folder should look like this:

Music Files
   Song1.mp4
   Song2.mp4
   ConvertMP4toMP3.bat

Simply double-click the batch file.

The script will:

• Convert your MP4 videos to MP3
• Extract artwork from the video
• Embed the artwork into the MP3
• Add metadata
• Create an organized MP3 folder

When it finishes, your folder will look like this:

Music Files
   Song1.mp4
   Song2.mp4
   ConvertMP4toMP3.bat
   MP3
       Song1.mp3
       Song2.mp3
