Burn Subtitles Into a Video, So They Can't Be Turned Off
Put the words into the picture itself, the way Reels, Shorts and TikTok need them. Choose the font, size, colour and position, and the video is rewritten on your device — free, with no watermark and no sign-up.
Your video never leaves your device. How?
In Accurate mode only the audio is sent to our server to be transcribed, then deleted. Choose "On this device" in the settings and nothing is uploaded.
Select or drop a video or audio file
MP4, WebM, MOV, MP3, WAV, M4A, FLAC, OGG. Your video stays on your device.
Click, tap, or drop a fileHow to burn subtitles into a video
Choose the video
Drop in the video you want the words printed onto.
Get the subtitles right first
AI writes them; correct any line before burning, because afterwards they are part of the picture.
Style them
Pick the font, weight, size, colour and whether they sit at the top, middle or bottom.
Burn and download
The video is rewritten on your device and downloads with the words in it.
Why burning in is the slow step
Every other step only reads the video. Burning in has to draw each subtitle onto each frame and write a new video out, so the picture is encoded again from start to finish. That is why it takes longer than making the subtitles did, and why it is worth getting the words right first.
It still happens on your device, using the browser's own video engine, so a long video takes a while on an older computer but never passes through a server and never comes back marked.
Features
They can't be switched off
The words are part of the picture, which is what Reels, Shorts and TikTok need, since those players ignore subtitle files.
Styled how you want
12 font families with bold and italic, 5 colours, 4 sizes and 3 positions.
No watermark
The burned video carries nothing but your own words.
Nothing uploaded
Your video never leaves your device. In Accurate mode only the sound is sent to be written out, and nothing is kept.
Frequently asked questions
Can I burn subtitles directly into my video?
Yes. Once the subtitles read correctly, choose the style and burn them in: the video is rewritten on your device with the words drawn onto each frame, and downloads with no watermark.
What fonts can I use for burned-in subtitles?
You can choose from 12 web-safe font families: Arial, Impact, Georgia, Times New Roman, Verdana, Trebuchet MS, Tahoma, Courier New, Comic Sans MS, Lucida Console, Palatino, and Garamond. Each can be combined with Bold, Normal, Italic, or Bold Italic styles. You also get 5 text colors (white, yellow, cyan, green, red), 4 sizes, and 3 positions (top, middle, bottom).
How long does subtitle generation take?
In Accurate mode, a few seconds, even for a 10-minute video, on phones too. On this device: on a laptop, roughly 4–5 times faster than the video plays (an 82-second video took about 15–21 seconds on a 2020 laptop once the model was loaded); phones are slower, and the first run also downloads the AI model (about 41 MB).
Can I change the subtitles after burning them in?
No, and that is the point of burning in: the words are pixels now, like anything else in the picture. Keep the original video, and if a line is wrong, correct it and burn again from the original rather than from the burned copy.
