Question 1

How do I add subtitles to a video permanently?

Accepted Answer

Upload your video (MP4, MOV, AVI, WebM, or MKV) and your SRT or VTT subtitle file. Our tool burns the captions into the video frames so they are always visible, and you download a single MP4 with subtitles permanently embedded. No video editing software or timeline work required.

Question 2

Is adding subtitles to video free?

Accepted Answer

Yes. Free tier is available after signing up for free. Upload your video and subtitle file and download the output with captions burned in at no cost within the monthly free limit. Paid plans start at $19/month for 450 minutes if you need to process more videos per month.

Question 3

What video formats are supported for adding subtitles?

Accepted Answer

MP4, MOV, AVI, WebM, and MKV are all accepted. The output file is an MP4, which is compatible with YouTube, Vimeo, Instagram, TikTok, and every major platform and device. If your original file is MOV or AVI, the output MP4 is ready for direct upload anywhere.
