Why TikTok videos need burned-in captions
Most people scroll with the sound off, and the ones who don't still read along. Captions that light up word by word hold attention through the first three seconds, which is the moment TikTok decides whether to show your video to more people.
TikTok's built-in auto captions help, but viewers can switch them off, you can't style them, and they appear as plain subtitles rather than the bold, word-by-word captions creators use. Burned-in captions look the same on every phone, in every repost and on every other platform you post to.
Where to put captions on TikTok (safe zones)
TikTok covers parts of your video with its own interface. Keep captions out of these areas so they are never hidden:
- The bottom ~20%: your username, caption text and the sound bar sit here.
- The right edge: like, comment, share and the profile icon run down the side.
- The top ~10%: the Following / For You tabs and the search icon.
The sweet spot is between about 55% and 75% of the way down the screen, centred. In Karaoke Captions, pick Middle or drag the captions up on the preview until they clear the interface.
How to add captions to a TikTok video, free
- Drop in your video. Vertical 9:16 straight from your camera roll or your editor. Nothing uploads.
- Check the words. Captions appear automatically, timed to each word. Tap any line to fix a name or a slang word.
- Pick a style. Classic is free: bold, uppercase, one to three words at a time. Pro adds 27 animated looks like Glide, Punch and Sticker.
- Export and post. Download the MP4 with captions burned in (no watermark) and upload it to TikTok.
Caption style that works on TikTok
- One to three words at a time. Short bursts read faster than full sentences on a small screen.
- Big, bold, high contrast. White or yellow with a dark outline reads on any background.
- Highlight the word being spoken. It pulls the eye along with the voice, which is the whole point of karaoke-style captions.
- Emphasise the hook. Turn on smart highlights, or list the key words, so numbers and strong words pop.
The same captions work for Instagram Reels and YouTube Shorts, which crop to the same 9:16 frame and have similar interface overlays.
Frequently asked questions
Is this TikTok caption generator free?
Yes. Unlimited videos with word-by-word captions and MP4 export, no watermark and no account. Optional Pro styles cost less than $2 a month.
Will TikTok compress my captions?
Bold captions with an outline survive TikTok’s compression well. Export at your video’s own resolution and avoid very thin fonts.
Can I use it on my phone?
Yes, in your phone’s browser, for shorter clips. For long videos a computer is faster and more reliable.
Do the captions work for Reels and Shorts?
Yes. Instagram Reels and YouTube Shorts use the same 9:16 frame. Keep captions in the middle band so neither app’s buttons cover them.
