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.
