No upload · No watermark · No minute quotas
TikTok caption generator
Word-by-word animated captions are the TikTok standard — and TikToks are short, so CaptionForge's free tier (videos up to 3 minutes) covers essentially every TikTok you'll make. Captions generate on your device with karaoke styling, and 9:16 safe-area guides keep them clear of the action rail, description and progress bar.
- 9:16 safe-area guides — default position clears TikTok chrome
- Karaoke word-highlight, pop, sweep and reveal animations
- TikToks are under 3 minutes — the free tier fully covers them
- No upload: your video goes straight from your drive to the export
How it works
- 1 Drop your 9:16 clip — no signup.
- 2 Captions generate locally in seconds with word-level timing.
- 3 Pick a karaoke style; the safe-area overlay shows TikTok's UI zones.
- 4 Fix any words, export 1080×1920 MP4, post it.
Frequently asked questions
Where should captions sit so TikTok's UI doesn't cover them?
Clear of the right-side action rail, the description/username block at the bottom, and the top edge. CaptionForge's 9:16 safe-area overlay draws exactly these zones, and the default caption position already clears them — drag to adjust if your footage needs it.
Why karaoke-style captions?
Word-by-word animation is the dominant caption format in short-form — one 2026 study of 756K shorts found 96.8% of captioned videos use animated word-by-word text. Viewers track the highlighted word, which holds attention on muted autoplay feeds.
Is this free for TikTok-length videos?
Yes — free covers unlimited videos up to 3 minutes, which is longer than the vast majority of TikToks (and longer than Submagic's $19/mo tier allows per video). 4 presets including karaoke highlight, 1080p export, no watermark.
Does the exported video have a watermark?
No — never, on any tier. You're posting to a platform that adds its own branding; your caption tool shouldn't add more.
Can I caption a video I already posted to TikTok?
Yes — download your video from TikTok (or use your original file, which is better quality) and drop it here. For pulling just the text out of a TikTok, the TikTok transcript page covers that workflow.
