FAQ
Can I add a custom image or album art?
Yes, absolutely. After uploading your MP3 file, click "Add image" to upload a custom cover image in JPG or PNG format. This image will display throughout the entire video, making it perfect for album artwork, podcast covers, or any visual branding you want to include.
Will my audio quality change during conversion?
No, your audio quality will remain exactly the same. The original MP3 track is embedded directly into the MP4 container without any re-encoding or compression. This means the bitrate, clarity, and all audio characteristics remain identical to your source file.
Is there a maximum file size for MP3 uploads?
You can upload MP3 audio files up to 1 GB in size. Larger files may take a bit longer to process, but they follow the same simple conversion process. Whether you're converting a short song or a long podcast episode, our converter handles files of all sizes efficiently.
Why convert MP3 to MP4?
Many popular platforms like YouTube, Instagram, Twitter, and TikTok require video files for uploads. Converting MP3 to MP4 allows you to share your audio content on these platforms where MP3 files aren't accepted.

Can I batch convert multiple MP3 tracks?
