TikTok meant that your ads should fit in seamlessly with non-advertising TikToks. Your TikTok ads should reflect the entertaining and unique nature of content created by non-commercial users.

It’s essential to keep in mind that when you decide to put your brand on TikTok, you also need to determine how to allocate your time between organic posts and paid ads. Each has pros and cons, and your TikTok advertising strategy will likely incorporate both.

TikTok Ad Specs for Video Ads and Image Ads

As a video platform, TikTok naturally supports various types of ads in the video medium.

Video Ads Specs

The TikTok app itself, as well as its separate news apps (BuzzVideo, TopBuzz, Babe), support video ads. However, since video ads are not uniquely available on the news apps the way image ads discussed below are, this guide to video ads will focus on the TikTok app. 

Here is a rundown of TikTok in-feed video ad specs: 

  • Format can be .mp4, .mov, .mpeg, .3gp, or .avi.
  • Your file size cannot exceed 500 MB.
  • Your bitrate must be 516 kbps or under. 
  • TikTok provides a series of short videos that users can’t stop watching, so video ads range in length from 5–60 seconds.
