How this Free MOV to MP4 Converter — Convert Apple Videos Online works
This converter transforms Apple QuickTime MOV files into universally compatible MP4 containers using FFmpeg WebAssembly in the browser. It offers two distinct conversion paths: re-muxing and re-encoding. The re-mux option copies existing video and audio streams directly into an MP4 container without any decoding or encoding, preserving 100% of the original quality at maximum speed. This works when the MOV already contains H.264 video and AAC audio streams.
For MOV files using Apple ProRes, HEVC, or other codecs that may not play on non-Apple devices, the re-encoding path uses libx264 with configurable CRF (Constant Rate Factor) quality. CRF 18 produces visually lossless output, CRF 23 provides an excellent quality-to-size balance, and CRF 28 prioritizes small file size. Audio is re-encoded to AAC at 128 kbps with the movflags=faststart flag for progressive web playback.
The tool reads MOV metadata to display file size and duration before conversion. After conversion, users can preview the MP4 directly in the browser and compare file sizes between the original MOV and resulting MP4.
