Frequently Asked Questions
Is this MP4 to MP3 converter free?
Yes! The FreeTools Guru MP4 to MP3 converter is completely free to use with no signup required.
Can I convert multiple MP4 files?
Yes. Upload two or more MP4 files and the tool bundles all extracted MP3 audio files into a single ZIP download.
Will the video be kept after conversion?
No. Only the audio track is extracted into an MP3 file. The original video is processed securely and deleted shortly after the job completes.
Why is my MP3 file smaller than the MP4?
MP3 stores only the audio stream, while MP4 also contains the video, so the extracted audio is much smaller than the full video.
