What is MP4?

MP4 (MPEG-4 Part 14) is the world's most widely used video format. Introduced in 2001, it has become the universal standard for digital video across all devices, platforms, and browsers.

MP4 files use efficient H.264 or H.265 compression to deliver excellent quality at small file sizes. The format supports video, audio, subtitles, and still images, making it versatile for any multimedia content.

From YouTube to Netflix, from iPhones to Android phones, from Windows to Mac—MP4 plays everywhere. It's the safe choice for any video project.

Why Convert to or from MP4?

MP4 is the default choice, but conversion is sometimes needed:

  • Convert TO MP4 – Make any video universally compatible
  • Legacy formats – Modernize AVI, FLV, WMV files to MP4
  • Apple videos – Convert MOV for cross-platform sharing
  • MKV compatibility – Convert to MP4 for devices that don't support MKV
  • Platform requirements – Social media and video sites prefer MP4
  • Special needs – Convert FROM MP4 for specific software requirements

Convert MP4 to Other Formats

How to Convert MP4 Files

  1. Upload your video – Drag and drop any video file or click to browse.
  2. Choose MP4 or other format – Select your desired output format.
  3. Download converted file – Get your video ready for any device or platform.

Pro Tip

For web uploads, use MP4 with H.264 video and AAC audio—this combination is hardware-accelerated everywhere and processes fastest on video platforms.

Common Mistake

Using unnecessarily high bitrates. Most viewers can't distinguish quality above 8-10 Mbps for 1080p video. Higher bitrates just waste file size and bandwidth.

Best For

MP4 is ideal for virtually everything: sharing, streaming, uploads, mobile playback, web embedding, and general video distribution. It's the universal choice.

Not Recommended

Avoid MP4 only when you need features it lacks: multiple audio tracks (use MKV), Apple editing workflows (use MOV), or royalty-free web video (use WebM).
