WM UploaderA free web tool that publishes finished short videos to TikTok from a browser, made for creators who edit on a computer.
Nothing. No paid plan, no advertising, and no registration beyond signing in with TikTok.
MP4, MOV and WebM, up to 100 MB, within the length limit your TikTok account allows. The studio shows that limit once your account is connected.
On the operator's storage (Cloudflare R2), only until TikTok has fetched it. Then it is deleted automatically.
TikTok requires AI-generated content to be labelled. The checkbox passes that label together with the post.
Not yet. A post goes out when you press the button.
One account at a time. Disconnect and connect the other account.
TikTok returns a reason and the studio shows it in plain words - usually the video is too long, the account has hit a posting limit, or too many unfinished drafts are waiting in the inbox.
Press Disconnect in the studio, or write to the address on the Support page.
