MPG to MP4 Converter

Convert MPG or MPEG camera clips to H.264 MP4 with AAC audio locally. Choose quality and resolution; no uploads. Interlaced footage is not deinterlaced.

    H.264 + AAC for browsers, phones and sharing.

    Advanced Settings

    Resolution caps height without enlarging. Odd dimensions round down for codec compatibility. MPG defaults to 24 fps. The first video and audio tracks are used; subtitles, chapters and metadata are not copied.

    Nothing gets uploaded. Videos are processed locally in your browser.

    No fixed server upload limit. Your device’s available memory and browser determine the practical limit.

    The video engine downloads about 31 MiB on first use. One video runs at a time. Current WebAssembly inputs must be smaller than 2 GiB; practical limits are often much lower. Google advertising may make separate network requests; file bytes and names are never passed to it. FFmpeg licenses and source.

    How to convert MPG to MP4

    1. Copy the original MPG or MPEG clip from your camera or archive to your device, select it above and wait for its metadata.
    2. Keep MP4 selected for H.264 video and AAC audio. Start with Auto quality, Original resolution and Original frame rate; choose High for more detail or Smaller File to trade detail for size.
    3. Convert and download locally. Play the MP4 in its destination app and inspect motion, audio synchronization and file size before processing more recordings.

    MPG and MPEG from older cameras and archives

    The .mpg and .mpeg extensions commonly identify MPEG program streams with MPEG-1 or MPEG-2 video, found in older digital-camera exports, desktop captures and archived clips. H.264 MP4 with AAC audio is easier to use in many current browsers, phones and sharing apps. This is re-encoding, not renaming; test the receiving app rather than assuming universal playback.

    Resolution, quality and interlaced recordings

    Original resolution avoids intentional resizing, although odd dimensions round down for codec compatibility. A lower resolution can reduce stored detail; it cannot recover missing camera detail. High quality can retain more detail at a larger size, while Smaller File accepts more compression. The MP4 is not guaranteed smaller than the MPG. There is no deinterlacing control: comb-like edges in moving subjects may remain, and changing frame rate does not remove them. Prepare interlaced footage in a desktop editor if needed.

    Support conditions and failed conversions

    Support depends on the actual streams, not the MPG filename. The current output uses the first video and first audio track, with subtitles and additional audio tracks omitted. Check that an intact, unencrypted source plays locally. If decoding fails, try another copy or a shorter clip prepared locally; unsupported codecs, damaged timestamps and memory pressure can prevent conversion. Browser preview support is separate from engine decoding. There is no server upload fallback.

    Create an MP4 copy of archived MPEG footage

    MPEG program streams can be bulky and awkward to share. An H.264 MP4 may be smaller, but the actual result depends on your source and quality setting. Interlaced footage is not automatically restored or deinterlaced.

    Understanding MPG and MP4

    MPG usually contains an MPEG program stream, with MPEG-1 or MPEG-2 video. It appears in older camera exports and archived desktop clips. Interlaced sources may retain combing because this first version does not offer deinterlacing.

    MP4 is a media container widely used for phone recordings, downloads and web video. This converter exports H.264 video with AAC audio; other MP4 sources can use different codecs.

    Compatibility after conversion

    H.264 + AAC for browsers, phones and sharing. Test the downloaded file in its intended application. Browser preview support and container conversion support are different capabilities.

    Quality, time and practical limits

    Start with Auto and Original resolution for a general playback copy. High uses more bits to retain detail; Smaller File trades some detail for space. A long or high-resolution recording can take longer than its running time, particularly on a phone. This version does not preserve HDR mastering metadata, subtitles or multiple audio tracks. Keep your original before evaluating a conversion.

    Local processing you can verify

    Open your browser’s Network panel before selecting a video. You will see engine and page downloads, anonymous tool usage events, and separate ad requests, but no request carrying the video or its filename. Cancel terminates the worker; clearing the batch releases retained results. More about privacy verification.

    GOOD TO KNOW

    Video conversion questions.

    How do I convert MPG to MP4?

    Choose a local file, wait for its metadata, select the output and quality, then convert and download. A batch is processed one video at a time. The engine downloads on first use; your videos do not upload.

    What will the MP4 file contain?

    H.264 + AAC for browsers, phones and sharing. Only the first video and audio tracks are selected. GIF has no audio; subtitles, chapters and metadata are not copied.

    Will the quality and file size stay the same?

    Video is re-encoded, which can change quality and size. High quality usually retains more detail and uses more space. Original resolution avoids intentional resizing, though odd dimensions round down for codec compatibility. Keep the source as your master copy.

    How long does conversion take, and how large can my file be?

    Time depends on duration, resolution, codec and device. Browser WebAssembly can be slower than a desktop encoder. There is no fixed server upload limit; device memory sets the practical limit. The current engine requires inputs below 2 GiB, and phones often need much smaller clips.

    Does FormatPlease upload or store my video?

    No. File bytes and names stay on your device. The browser downloads the engine from this website and runs it in a worker. Separate advertising requests may occur, but the converter does not provide your files to advertising or analytics.

    Why might a MPG file fail?

    A container extension does not identify every codec inside it. Unsupported codecs, encrypted files, damaged containers and memory pressure can prevent conversion. There is no server upload fallback; try another source or a shorter clip.
