How do I convert an MP1 file to MP4?

Open the MP1 to MP4 tool, drag and drop your .mp1 audio file, choose the MP4 output format, and optionally set the audio bitrate (AAC recommended). Click Convert, then download the new MP4 file. You can batch convert multiple MP1 files with the same settings.

Why should I convert MP1 to MP4?

MP1 (MPEG-1 Layer I) is an obsolete audio codec with large file sizes and poor device support. MP4 is a universal container that works on phones, smart TVs, and editing software. Converting reduces file size by up to 60% when using AAC audio, while making the file playable on almost any modern platform.

What happens to audio quality and metadata when converting from MP1 to MP4?

LetsConvert re-encodes the audio stream into AAC (lossy) or ALAC (lossless) inside the MP4 container. You can select the output bitrate; choosing 256 kbps or higher preserves perceptual quality, even though MP1's original 384 kbps stream is discarded. Sample rate, channel count, and ID3 tags such as artist, album, and title are automatically copied to the MP4.

Yes, MP1-TO-MP4 on LetsConvert is 100% free with no registration or hidden fees required.
