A sensible place to start
For a vertical source, keep its aspect ratio and try 1080p or 720p Balanced at 30 FPS.
The compressor above is preconfigured for this use case. Actual results still depend on the source codec, motion and detail.
Why it works
Spend fewer bits, deliberately
Social apps re-encode uploads. Starting with a clean H.264 MP4 and a sensible bitrate helps avoid sending needless data.

Frequently asked questions
Is TikTok video compression private?
Yes. Standard compression runs inside your browser. The video file is not sent to a VideoShrink server.
Will the output size be exact?
Target-size mode aims slightly below your limit, but container overhead and unusual source files can make the final size vary.
Why can compression take a while?
Encoding is demanding work. Duration, resolution, device speed and browser memory all affect processing time.
Make your video easier to share
Private browser compression. No account required.
