TikTok
Schedule TikTok videos and photo posts. Batch a week of exports in one sitting.
TikTok output arrives in batches — you sit down with a folder of exports rather than one video. So the part worth optimising is not the single-post flow, it is dropping thirty files in at once and having them spaced out sensibly across the next two weeks.
Bulk upload up to 50 per batch.
Built for the batch
Short-form video does not get made one piece at a time. You film, you edit several, and you end up with a folder.
So the flow that matters is: select the folder, get one post per file, give a start time and an interval, and let the times be computed. Fifty per batch, and each row stays editable in case two of them need a different caption or slot.
That is the same bulk flow every platform here uses, described in full on bulk scheduling.
Photo mode counts too
TikTok accepts image posts, and it allows more media items per post than anything else in the list above. Worth knowing if you are moving carousel content across from Instagram — the format exists on TikTok, and it is not the same as posting a video.
Reusing the video is fine, reusing the caption is not
The same vertical video legitimately belongs on TikTok, Reels, and Shorts. That is not lazy, it is the format working as intended.
The caption is where cross-posting becomes obvious. TikTok copy is short and casual, a YouTube description is doing search work, and an Instagram caption assumes a different reading context. Auto-repurposing rewrites per destination so one export does not arrive three times with identical text.
Every scheduled publish counts separately against your monthly cap. One video going to three platforms is three posts.

Questions
Frequently asked questions Everything the first evaluation usually needs.
- Can I bulk schedule TikTok videos?
Yes. Pick up to 50 files and Postonus creates one post per file, then staggers them from a start time and interval you choose. Every computed time stays editable.
- Does TikTok photo mode work?
Yes — TikTok accepts image posts as well as video, and the table above shows how many items one post can carry. It is the highest media count of any platform here.
- Do posts publish automatically or do I get a reminder?
They publish automatically at the scheduled time through TikTok’s official API. There is no notification for you to act on.
- Can I reuse my TikToks on Reels and Shorts?
The video, yes. The caption usually should not be reused verbatim — the conventions differ enough that a copied caption reads as cross-posted. Auto-repurposing reshapes the text per destination.
- Do I need a business account?
Content posting through TikTok’s API requires an account with publishing permissions granted during authorisation. The connection flow tells you if your account cannot be used.
