TikTok image compression FAQ
TikTok supports JPEG, PNG, and WebP. For slideshows, use 1080×1920 vertical images. Each image can be up to 25MB, but keeping files under 5MB improves upload speed.
The 9:16 vertical ratio (1080×1920 pixels) is ideal for TikTok as it fills the entire phone screen. Square (1:1) images also work but leave black bars at the top and bottom.
