Understanding TikTok Video Size
TikTok video size refers to three things: dimensions (1080 x 1920 pixels), file size (max 287.6 MB iOS / 72 MB Android), and duration (up to 10 minutes). All three must meet TikTok's requirements for successful upload.

How to Reduce TikTok Video Size
Export at 1080p instead of 4K. TikTok downscales to 1080p anyway, so higher resolutions waste file size.
Set video bitrate to 8-10 Mbps. Lower bitrate = smaller file size with minimal quality loss.
H.265 (HEVC) provides better compression than H.264, reducing file size by 30-50% with same quality.
Shorter videos = smaller files. Cut unnecessary footage to reduce file size.
Use video compression apps like HandBrake, Adobe Media Encoder, or online compressors to reduce file size.
Common TikTok Size Problems & Solutions
Solution: Compress video to under 72 MB (Android) or 287.6 MB (iOS). Use H.265 codec or lower bitrate.
Solution: Export at 1080 x 1920 minimum. Don't upscale lower resolution videos.
Solution: Use 9:16 aspect ratio. Crop horizontal videos to vertical before uploading.
Solution: Check internet connection, use MP4 format, ensure video isn't corrupted, restart app.
