Compress Video for Douyin

We did not confirm an official Douyin consumer file-size cap on a help page we can cite. The app accepts large uploads, and it also recompresses them. This page preselects 50MB so a vertical clip can finish on a mobile network. If Douyin’s composer shows a different limit, use that number instead.

How it works

  2. 2Keep 50MB, or raise it if the estimate looks too soft.
  3. 3Compress, download, and upload the file in Douyin.

Compress before the app does

A 1GB 4K export is slow on a mobile network and gives Douyin a huge file to recompress. 50MB at 1080p is a practical middle: fast to send, enough bitrate for a short clip.

50MB is not presented here as Douyin’s rule. It is the preset this page selects.

The tool does not crop to 9:16. Crop first if you need a vertical frame.

What fits in 50 MB

Planning estimate from Slimvid’s size formula: 97% of the byte cap, a small audio reserve, then a lower resolution when the video bitrate would look bad. It is not a measured encode of one clip. Motion, codec and audio change the file.

FAQ

Douyin video size FAQ

What file size does Douyin allow?
We could not confirm a single official number. This page uses 50MB so the upload is fast. Change the target if the app tells you otherwise.
Do I need a vertical video?
Douyin’s feed is vertical, but this tool does not crop. Compress the file you have, or crop in an editor first.
Will my sound be kept?
Yes. Audio is re-encoded inside the size budget. Keep the original if you plan to replace the sound inside Douyin.
