Recommended settings
Vertical 1080 × 1920 is all TikTok needs — 4K source files are wasted bandwidth.
TikTok re-encodes every upload, so a clean balanced MP4 is the sweet spot.
Compress before uploading when you are on mobile data or a slow connection.
Questions
Does TikTok compress my video again?
Yes. TikTok always re-encodes uploads, so sending a clean, reasonably sized MP4 loses nothing.
What format does TikTok prefer?
MP4 with H.264 video and AAC audio is the most reliable format for TikTok uploads.
