Frequently Asked Questions
MPG (MPEG Video (short)) is a video container format that bundles one or more video streams, audio tracks, and optional subtitles into a single file. The container format determines how metadata is organised and which codecs can live inside; the visual quality itself depends on the codec (H.264, H.265, VP9, AV1) rather than the MPG wrapper. It is part of the video files family.

VLC, MPV and PotPlayer play nearly every MPG file on desktop. Browser support varies: modern Chromium, Firefox and Safari play common containers via the HTML5 <video> tag, but niche MPG variants may fail. If a device refuses your MPG, convert to MP4 with our MPG to MP4 converter for universal playback.

If a device refuses your MPG, converter to MP4 com our MPG to MP4 converter para universal playback.
Upload your MPG to KaijuConverter and pick MP4, MOV, MKV, WebM, or any other target. Our pipeline uses FFmpeg under the hood and stream-copies when codecs are compatible (no quality loss) or transcodes at high-quality defaults otherwise. Conversion runs server-side; both files delete within two hours.
Only when the target requires re-encoding. If the codecs inside MPG match what the target container supports, FFmpeg stream-copies the streams and the output is bit-identical to the source. Transcoding uses transparent quality defaults (CRF 20–23 H.264) and produces output indistinguishable from the original at normal viewing distance.
