Compress a video for TikTok

TikTok re-encodes everything anyway
Sending a bigger file does not preserve more quality, it only makes the upload slower and more likely to fail on a weak connection. Compressing first costs you nothing visible.
Vertical, and under 60 seconds where it counts
TikTok accepts other shapes, but anything that is not 9:16 gets letterboxed in the feed. The crop you choose beats the crop it chooses for you.
Echoia does the rest: publishing to ten networks, every comment and message in one inbox. Free for three accounts.
