- Save the video
Your file stays on your device. Nothing is uploaded.
How to add subtitles to a video
- Choose your video and the language spoken, then press Create subtitles.
- Check the lines next to the video and fix any word.
- Pick a style and where the captions sit, keep the frame or make it 9:16, then press "Make video".
- Watch the result, then download it or send it from your phone.
Burned in, or as a file
Burned-in captions are part of the picture, so they show everywhere, even where people watch without sound. If you want viewers to turn them on and off instead, save the lines as SRT or VTT and upload that file next to the video on YouTube.
Caption styles
- Clean: white letters with a dark outline. Reads well on any picture.
- Box: white letters on a dark box, like TV subtitles.
- Bold: big yellow capitals, the look many Reels and TikToks use.
- Minimal: smaller white letters with a soft shadow, for calm videos.
Your videos stay on your device
Nothing is uploaded. The speech model and the video encoder run in your browser, so your video is never sent anywhere to be captioned.
FAQ
Frequently asked questions
Short answers about how this tool works on your device.
Can I upload the subtitles to YouTube?
Yes. Save them as SRT, then in YouTube Studio add subtitles to your video and upload the file.
Is Snipmill free?
Yes. Snipmill is free to use and needs no account. Videos can be up to 10 minutes long: plenty for Reels, TikTok and Shorts. More with Premium is coming soon.
Is there a watermark?
No. We never add a watermark.
Which languages work?
The speech model knows about 100 languages; English is the most accurate. You can also turn speech in another language into English captions. On some browsers, captions in scripts other than Latin can only be saved as SRT or VTT.
Can I use subtitles I already have?
Yes. After choosing the video, press "or use my SRT/VTT file" and pick your subtitle file. Its lines appear next to the video, ready to style; the speech model is not needed.
How long does it take?
Turning speech into text is usually faster than the video plays, on a computer with a graphics chip. Making the video takes about as long as other video tools here: a few seconds per minute of video on a recent computer, longer on a phone.
