Frequently Asked Questions
Why would I need to convert MP3 to MP4?
Converting MP3 to MP4 is useful when you want to upload audio content to video platforms like YouTube, share audio on social media that requires video format, create simple music videos, or add audio to presentations. MP4 is a video container format that can include both audio and video streams.
What happens to my audio quality during processing?
Our system maintains the original audio quality of your MP3 file. We provide the processed audio file directly without any quality loss, preserving all audio characteristics including bitrate, frequency, and stereo/mono settings.
Is there a file size limit for conversion?
Yes, our free converter has a file size limit of 50MB per MP3 file. This limit accommodates most standard audio files, including songs, podcasts, and short audio recordings. If you need to convert larger files, consider splitting your MP3 into smaller parts before uploading.
How secure is my data during the conversion process?
We take data security seriously. All file transfers are secured with encryption, and your files are automatically deleted from our servers after conversion or after a short period (typically 24 hours) if you don't download them. We do not access, view, or share the content of your files with any third parties.
What video quality should I choose?
The choice depends on your needs. Standard quality (480p) creates smaller files that are suitable for basic sharing and viewing. HD (720p) offers a good balance between quality and file size. Full HD (1080p) provides the highest quality but results in larger files. Choose based on where you plan to use the video and your bandwidth considerations.
Why am I receiving an MP3 file instead of an MP4?
Due to system limitations, our tool currently provides the processed MP3 file directly. To convert this to an MP4 video, you can use free desktop software like VLC Media Player, Windows Movie Maker, or online services that support this conversion. We're working on adding direct MP4 conversion in a future update.
