About MPEG
MPEG files (.mpg, .mpeg) are MPEG-1 or MPEG-2 program streams, the standards behind Video CD and DVD video.
Older camcorders, DVD-era video files and broadcast archives.
MPEG-1 and MPEG-2 compress far less efficiently than H.264, so the files are large for their quality.
Convert MPEG to AAC online free, no account required — AAC is the lossy audio codec that succeeded MP3.
Change MPEG to AAC without losing quality — convert MPEG to AAC free in your browser.
Why does my MPEG video look soft on a modern screen? MPEG-1 and MPEG-2 were designed for VCD and DVD resolution, so upscaling a 576-line picture to 4K shows every limitation of the era.
About AAC
AAC (Advanced Audio Coding) is the lossy audio codec standardised in MPEG-2 and MPEG-4 as the successor to MP3; at the same bitrate it generally sounds better than MP3.
It is the audio in most MP4 videos, in Apple Music and on YouTube; a .aac file is a bare AAC stream without a container.
A bare .aac stream has only limited room for tags and cover art, so music players usually expect AAC inside an M4A file.
Why convert music to AAC instead of MP3? At the same bitrate AAC sounds better, and every modern phone, computer and streaming service decodes it.
What changes when you convert MPEG to AAC
- The soundtrack of the MPEG is re-encoded as AAC at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the AAC file contains the audio track of your MPEG, and the picture is dropped.
Settings you can change
Before you convert MPEG to AAC, you can adjust: Audio codec, Rate control, Audio bitrate, Quality (VBR), Sample rate, Channels, Normalize loudness, Trim start, Trim duration, and Keep tags.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted AAC file is kept for 2 hours, then deleted.
