Best Video Format for Websites

Website video is about playback compatibility and bytes — not creator-app timelines. Deliver an MP4 (and optional WebM) that browsers can play without plugins.

Quick take: Ship MP4 for almost every site embed; add WebM when you control dual sources. Convert MOV → MP4 for uploads.

MP4 as the default

Near-universal HTML5 support. Keep resolution realistic for the player size and compress delivery copies.

WebM and other options

WebM can be efficient in Chromium-heavy audiences. Avoid relying solely on MOV/MKV for public pages.

Convert then compress

Use MOV→MP4 or MKV→MP4, then the Video Compressor if the file still exceeds CDN or CMS limits.

Key points

  • MP4 is the compatibility default.
  • Convert camera containers before embed.
  • Compress a delivery copy — keep the master.

FAQ

Is GIF better for short loops?

Usually no — a short MP4 loop is smaller and cleaner than a huge GIF for most sites.
