MP4 tips
🎬
MKV is a flexible container but many TVs, phones, and editors don't support it. MP4 plays almost everywhere.
📤
Most social platforms and upload forms accept MP4 but not MKV — convert before uploading.
⚡
Large MKV files take time to re-encode in the browser. The converter is best on desktop for big files.
🔒
No upload means no file-size cap and full privacy for your library.
