Compare MP4 and MKV for compatibility, multi-track support, and download workflows — with practical PasteGrab preset advice.
Overview
MP4 and MKV are both containers — neither guarantees better quality by name alone. The difference is compatibility vs flexibility: MP4 wins for phones, browsers, and social pipelines; MKV wins for multi-track archival.
When downloading public TikTok, Reels, or Vimeo clips, you will almost always want MP4 or Best quality from PasteGrab. MKV enters the conversation for local archival after download, not during link-based fetch.
Compare the codecs inside each file (H.264, H.265, VP9) using your player's info panel — that matters more than the extension.

How it works
Editing, archival, audio reference, or quick share — each goal favors different formats and quality levels.
Social clips often work in MP4; audio-only workflows favor MP3. See our format comparison guides for tradeoffs.
Select Best quality for masters, 720p for smaller files, or MP3 when you only need audio — before you preview the link.
Check resolution, bitrate, and audio tracks in your player or NLE before committing to a workflow.
Benefits
MP4: universal on iOS, Android, Windows, web. MKV: excellent in VLC, weaker on mobile without conversion.
MKV holds multiple audio and subtitle tracks; MP4 can but rarely does in consumer social files.
Use MP4 or Best quality for social downloads. Remux to MKV locally only if your DAM requires it.
