    Getting a good result

    Two kinds of conversion

    A video file is a container (MP4, MOV, MKV) holding picture and sound that were compressed with a codec. If your file already holds H.264 picture and AAC or MP3 sound, as most MOV and MKV files from cameras and screen recorders do, the tool lifts them out and places them in an MP4 container unchanged. That takes seconds and loses nothing. If the picture uses another codec (HEVC from a recent iPhone, WMV, MPEG-2, VP9), it is re-encoded to H.264 so that it plays everywhere.

    Why MP4

    MP4 with H.264 video and AAC sound is the one combination that every phone, browser, television, editing program and social platform accepts. YouTube's upload guidance names exactly this: an MP4 container, H.264 video, AAC sound.

    iPhone videos that will not open on Windows

    Recent iPhones record HEVC (H.265) inside a MOV file. Older Windows PCs, some browsers and some editing software cannot play it. Converting here produces H.264, which they can. The picture is re-encoded once at a high quality setting.

    Video to MP4 converter: common questions

    Will I lose quality?

    Not if your file already holds H.264 video: it is repackaged, and the result page says so. Other codecs are re-encoded once at a high quality setting (CRF 20), which is hard to tell from the original.

    Why is my MP4 bigger than the original?

    A newer codec such as HEVC or VP9 packs the same picture into fewer bytes than H.264. Converting to H.264 for compatibility can make the file noticeably larger. Choose Balanced quality or a lower resolution if size matters.

    How long can the video be?

    H.264 files are repackaged at any length up to 60 minutes. Files that need re-encoding can be up to 5 minutes. Both are limited to 100 MB.

    Can I convert a GIF to MP4?

    Yes. An MP4 of the same animation is usually a small fraction of the GIF's size.

    Does it keep subtitles and extra audio tracks?

    It keeps the first video track and the first audio track. Subtitle tracks and extra languages inside an MKV are not carried over.
