Codec & Container Notes
MP4 often wraps H.264/AAC—the widest playback path. Source codecs like ProRes or high-bitrate HEVC may re-encode with quality loss. Prefer direct camera H.264 when you only need container compatibility.
Duration & Size Limits
Long 4K sources take more time and memory. Short social clips convert faster. For multi-hour masters, offline FFmpeg pipelines remain more appropriate than browser one-shots.
Camera MOV? Use the MOV Converter. Web delivery can stay WEBM. Grab a thumbnail with the Video Frame Extractor.

How MP4 Converter differs from typical alternatives
Compared with MP4 video converters such as FreeConvert: FreeConvert displays heavy advertising and may require accounts for longer videos or batch conversion queues. Big File Sharing focuses on free one-off jobs, no mandatory signup, and short-lived temporary files instead of account-centric project history.
