How to Choose the Best Video Format in 2025: MP4, WebM, MOV, and More Explained

Choosing the right video format can make or break your content’s quality, compatibility, and upload speed. In 2025, there are more options than ever—so which should you use? This guide explains the pros, cons, and best use cases for each major format.

Why Video Format Matters

• Compatibility: Not all formats play everywhere. The right choice ensures your video works on all devices and platforms.
• Quality vs. File Size: Some formats offer better compression, keeping quality high and file size low.
• Platform Requirements: YouTube, Instagram, TikTok, and others have preferred formats for uploads.

• Tip: Use for YouTube, Instagram, TikTok, and most web uploads

WebM (VP9/AV1)

• Best for: Modern web delivery, especially on Chrome/Firefox
