Frequently asked questions
Why is MKV not always playable?
MKV is a versatile container often used with codecs that TVs or phones do not support. MP4 with H.264 + AAC is the safest universal choice.
Will the quality drop?
When the source already uses H.264/AAC the video is remuxed without re-encoding, keeping quality intact. Otherwise it is re-encoded at high quality.
Is there a size limit?
Files up to 500 MB are supported; conversion runs entirely in your browser.
