How to download TikTok videos as MP4

Open TikTok, find a video you like, and tap Share → Copy link.
Paste the link into the TikItDown field above and press Download.
Choose the MP4 download option. The file saves to your device as a standard .mp4.

The file downloads as a regular .mp4 - the same format you get from a camera, from YouTube, or from any video editing app. No special player needed, no conversion step, no file renaming.

Why MP4 is the right format

There are dozens of video formats out there - WebM, AVI, MKV, MOV, FLV - but MP4 is the one that works on virtually everything. Here's why that matters for TikTok downloads:

Universal playback - every phone, computer, tablet, and smart TV plays MP4 natively. No codecs to install, no "format not supported" errors.
Messaging-friendly - WhatsApp, Telegram, iMessage, Discord, and every other messaging app handles MP4. You can send a downloaded TikTok video to anyone without worrying if they can open it.
Editing compatible - CapCut, iMovie, Premiere Pro, DaVinci Resolve, Final Cut Pro - they all import MP4 files without conversion.
Social media ready - if you want to repost a clip to Instagram, YouTube Shorts, or Twitter, MP4 is the format those platforms expect.
Small file size - MP4 uses efficient H.264 or H.265 compression, so a TikTok video that's 1080p and 30 seconds is usually only 3-5 MB.

What you can do with a TikTok MP4 file

Watch offline - save TikTok videos to your phone and watch them on flights, commutes, or anywhere without internet.
Share with anyone - send a TikTok video to friends, family, or group chats as a direct MP4 file. They don't need TikTok to watch it.
Edit and remix - pull the MP4 into CapCut, iMovie, or any video editor to create compilations, reactions, or mashups.
Set as wallpaper - many phones let you set a video as your lock screen or home screen wallpaper. An MP4 file works for this.
Archive favorites - TikTok videos disappear when creators delete them or get banned. An MP4 saved locally stays forever.

MP4 vs MP3: which do you need?

If you only want the audio - a song clip, a sound bite, a voiceover - the TikTok MP3 downloader gives you just the audio track as an MP3 file. It's smaller and perfect for ringtones or listening offline.

If you want the full video with visuals - the dancing, the tutorial, the scenery - download as MP4. You get both the video and the audio in a single file.

Compatibility across devices

The MP4 files TikItDown produces use the H.264 codec, which is supported by every device made in the last 15 years. Specifically:

iPhone (iOS 12+) - plays MP4 in Photos app and Safari. Downloads save to Files by default.
Android (5.0+) - plays MP4 in the default video player and Chrome. Downloads save to your Downloads folder.
Windows 10/11 - plays in the built-in Movies & TV app, Windows Media Player, or any browser.
macOS - plays in QuickTime, Safari, or any browser. Also compatible with iMovie and Final Cut Pro.
Smart TVs - most modern TVs play MP4 from USB or DLNA. Transfer the file and watch on the big screen.
