TikTok Video Requirements
TikTok supports vertical videos in 9:16 aspect ratio at 1080x1920 resolution. The maximum file size is 287MB, and videos can be up to 10 minutes long (though most perform best at 15-60 seconds). Supported formats include MP4, MOV, MPEG, AVI, and FLV, with MP4 being the recommended format.
How to Compress Video for TikTok
Upload your video, trim it to your desired length using our trimmer tool, then compress with the 'Best Balance' preset. If your video is horizontal, consider cropping to vertical 9:16 format before uploading. The compressed video will be ready to upload to TikTok in seconds.
Optimizing Video Quality for TikTok
TikTok's algorithm favors high-quality videos. Use 1080x1920 resolution at 30fps for optimal results. Avoid over-compressing — the 'Best Balance' preset provides the right trade-off between file size and quality. For videos with lots of motion, you may need a higher bitrate to prevent artifacts.
TikTok Upload Tips
Upload videos during peak engagement hours (7-11 PM local time) for maximum reach. Keep videos between 15-30 seconds for highest engagement. Use trending sounds and hashtags. Compress your video before uploading to ensure fast upload and immediate processing on TikTok's servers.
