To post a Pin on TikTok by hand, save its image or video and upload it in TikTok. PostOnce posts each new Pin for you: image Pins as photo posts, video Pins as TikToks.

An image Pin posts as a TikTok photo post, so a static Pin never has to be rebuilt as a video first.
A multi-image Pin posts as one swipeable TikTok photo post, with every image in it.
Video Pins post as TikToks. If one runs longer than your TikTok account allows, Split videos if too long posts it in parts.
TikTok adds a track to photo posts. Video Pins keep their own audio, though TikTok may mute licensed music.
The Pin's description, or its title, becomes the caption. Rewrite caption with AI makes the first line searchable. The Pin's link stays on Pinterest.
Yes, your own Pins. PostOnce posts each new image Pin to TikTok as a photo post through TikTok's official posting API, and each video Pin as a TikTok.
Only Pins you made or have the rights to. Saving a Pin doesn't make someone else's photo yours, so PostOnce is for republishing your own Pins.
Yes. TikTok photo posts take still images, so an image Pin posts as it is and TikTok adds a track to it.
No. PostOnce doesn't copy a Pin's destination link, so put your site in your TikTok bio instead.
Up to your TikTok account's own limit, which PostOnce reads before posting. Turn on Split videos if too long and longer Pins post in parts.
Yes. The existing-posts option sends Pins you've already made, on paid plans and in the trial.
Not by itself. TikTok gets an ordinary upload through its official posting API, the same way schedulers post, and How2Rizz grew to about 15k TikTok followers that way. New or dormant accounts start slow regardless, so post normally for a while first.
