YouTube to TikTok converter: from 16:9 to vertical, captioned clips

A YouTube video is the wrong shape and the wrong length for TikTok. Splicora fixes both: paste the link, and its AI cuts the best moments, reframes them to 9:16 with the speaker kept in frame, burns in captions and drafts the TikTok caption — then posts to TikTok on a schedule if you want.

How it works

4 steps, under a minute

1

Paste the YouTube link

The tool previews the video so you can confirm it is the right one.

2

Create a free workspace

Converting needs storage and credits; the link is carried into your free Splicora account.

3

Choose moments and format

Keep the whole video reframed to 9:16, or let the AI cut it into scored TikTok-length clips.

4

Export or post to TikTok

Download the MP4s or connect TikTok and schedule them natively.

What "converting" a YouTube video to TikTok really means

The format change is the easy part. A landscape video cropped to vertical loses two thirds of the frame, so where the crop sits matters: Splicora's AI video resizer tracks the face or the moving subject and keeps it in the vertical window. The length change is the harder part. TikTok viewers finish short videos and abandon long ones, so the better conversion is not the whole video squeezed vertical but the strongest moments cut out of it — which is what the AI clip generator does.

On top of both, TikTok is watched with the sound off more often than not, so animated captions are burned in by default, and a hook covers the first two seconds.

Two ways to convert

  • Whole video, reframed — for a video that is already short. Select 9:16 in the resizer with face tracking on, add captions, export.
  • Clips, cut by the AI — for anything longer than a minute or two. Splicora finds the moments, cuts and reframes each one, captions them and drafts a TikTok caption and hashtags for each.

Posting to TikTok

Connect your TikTok account once under Connections and the converted clips can be scheduled from the calendar, published natively with their captions. The same clips go to Reels and Shorts with their own copy, and an auto-posting workflow can repeat the whole conversion for your next YouTube upload without you.

What changes between YouTube and TikTok

  • Shape — 16:9 to 9:16, with the subject tracked so the crop follows the speaker.
  • Length — minutes to seconds; the AI cuts the moments that stand alone rather than trimming the whole video.
  • Sound — captions burned in, because most TikTok viewing starts muted.
  • Opening — a hook in the first two seconds, where YouTube viewers will wait for an intro.
  • Copy — a short caption and a handful of hashtags, written for TikTok rather than pasted from the YouTube description.

Every one of those is handled in the conversion, and each can be adjusted in the editor before you post.

Questions people ask

Splicora fetches the video from the link you paste to process it; you never handle the file yourself. Only convert videos you own or have permission to reuse.

Yes. AI face tracking moves the vertical crop to follow the subject, so a speaker who leans or walks is not cut off.

Short. The AI trims clips to a length viewers finish, and you can adjust any of them.
