The best free mp4 to mp3 converter that still works in 2025?

Free online MP4 to MP3 converters can indeed be inconvenient, especially for large files. Here’s why I generally recommend avoiding them for bigger videos:

* Large MP4 files can take a long time to upload to the server and then download the converted MP3, which can be frustrating and time-consuming.
* Many online services impose restrictions on the maximum file size, so larger videos may not be supported without paying for premium features.
* Uploading personal or sensitive videos to online services raises privacy concerns, as files are transmitted over the internet and stored on third-party servers.
* The process depends on a stable internet connection; interruptions can ruin the conversion process.
* Sometimes, online converters may produce lower quality outputs or encounter bugs with certain file formats.

In contrast, using offline MP4 to MP3 software allows you to:

* Convert large files locally without upload/download delays.
* Maintain better control over your data privacy.
* Save time when processing multiple or large files.
* So, for large MP4 files, offline tools are usually more efficient, private, and reliable.
