Convert a video file to a different container format — MP4, MKV, AVI, MOV, or WebM.
Frequently asked questions
MP4 is the most widely compatible choice for sharing and playback across devices; WebM is common for web use; MKV and AVI/MOV are often used for archival or specific editing workflows.
Converting between formats re-encodes the video, which is effectively lossless for most practical purposes at default quality settings, though repeated re-encoding over many rounds can gradually reduce quality.
