Frequently Asked Questions — MOV to MP4 Video Converter
Technical details, privacy guarantees, and usage tips for our client-side mov to mp4 video converter on convert.my.id.
How does MOV to MP4 Video Converter run inside my browser without a server?
convert.my.id compiles FFmpeg to WebAssembly (@ffmpeg/ffmpeg). Your media file is loaded into an isolated in-memory virtual filesystem (MEMFS) and transcoded directly by your CPU in-browser.
Are my private audio or video files uploaded to convert.my.id servers?
Never. Zero bytes of your video or audio leave your device. All transcoding happens 100% locally inside your browser tab.
What is the maximum file size supported by MOV to MP4 Video Converter?
Because processing occurs in browser WebAssembly memory, files up to 500MB–1GB can typically be transcoded depending on your device's available RAM.
