Repurpose YouTube videos for TikTok
Your YouTube channel is already full of footage that would do well on TikTok. VoxCut takes those long uploads, pulls the best moments, reframes them to vertical, adds captions, and posts them straight to TikTok. It runs in your browser, with nothing to install and a free plan to start.
Pull the best moments out of a long YouTube video
A 20-minute YouTube video usually hides three or four moments worth their own TikTok. Best Moments uses AI to find the strongest segments so you don't have to scrub the timeline looking for them.
When you want volume instead, Clip Factory splits one long video into a batch of short vertical clips in a single pass. Run it on an old upload and you walk away with a week of TikToks to review, not one.
This is repurposing, not re-recording. You start from a video that already exists on YouTube and end with clips built specifically for a vertical, fast-scrolling feed.
Reframe to vertical and caption for a muted feed
YouTube is widescreen; TikTok is vertical. VoxCut reframes your horizontal footage to 9:16 so the speaker and the action stay in frame instead of getting cropped out at the edges.
Most TikToks are watched on mute, so Auto Captions adds word-level, animated, burned-in subtitles you can style to match your look. Captions are generated automatically and support multiple languages, and you can drop in auto B-roll or stock footage to keep slower stretches moving.
Hooks and a consistent look across every clip
TikTok decides whether to keep watching in the first second, and a YouTube intro rarely earns that. AI Tools generate fresh hooks, titles, and descriptions written for the platform, so each repurposed clip opens like it belongs on TikTok.
Brand Kit locks your fonts, colors, and watermark across every export, so a batch of clips from the same channel looks like a set rather than ten unrelated uploads. Voice Studio adds TTS voiceovers and speech-to-text when you need narration or a clean transcript.
Auto-post straight to TikTok
Once a clip is cut, reframed, and captioned, VoxCut auto-posts and schedules it straight to TikTok from the editor, so you can queue a steady run of clips from your back catalog instead of exporting and re-uploading each one by hand.
It posts to YouTube too, which is handy if you also want to keep a Shorts feed going. Everything runs in the browser across 10 UI languages, with a free plan to try and paid plans from $5.67/month when you need higher limits.
Frequently asked questions
How does VoxCut turn my YouTube videos into TikToks?
You start from a long YouTube video, then Best Moments uses AI to surface the strongest segments or Clip Factory splits the whole thing into a batch of vertical clips. Each clip gets reframed to 9:16, captioned, and given a TikTok-ready hook before VoxCut posts it to TikTok for you.
Is this the same as making YouTube Shorts?
No. Making Shorts keeps clips inside YouTube. This workflow is about repurposing existing YouTube footage for TikTok specifically, with vertical reframing, TikTok-oriented hooks, and auto-posting to TikTok. VoxCut can publish to both, so you can do one, the other, or both from the same cut.
Can VoxCut post the clips to TikTok automatically?
Yes. Auto-posting and scheduling go straight to TikTok (and YouTube) from the editor, so you can line up a run of clips from one long video without downloading and re-uploading each file by hand.
What about captions and languages?
Auto Captions generates word-level, animated, burned-in subtitles in many styles and supports multiple languages, which matters on a feed people scroll with the sound off. The VoxCut interface itself is available in 10 languages.
Is there a free plan, and what does it cost?
There's a free plan you can sign up for and start with. Paid plans begin at $5.67/month for higher limits and more output. VoxCut is fully browser-based, so there's nothing to install.
