MP4 is the recommended file format for TikTok ads. It's universally compatible across devices and platforms. MOV is also fully supported. Keep file sizes under 500 MB for reliable uploads.
TikTok ads can be 5-60 seconds long, with up to 10 minutes supported for some content types. However, 9-15 seconds is the recommended length for optimal engagement and completion rates. Every second should earn its place.
