Frequently Asked Questions
Is the subtitle adder free?
Yes. Add subtitles to videos for free with no signup, no watermark on downloads, and no software to install.
What is the difference between burn and soft subtitles?
Burned subtitles are permanently embedded into the video pixels — they cannot be turned off. Soft subtitle tracks are stored separately inside the container file and can be toggled on or off in any media player like VLC.
What subtitle format is supported?
SRT (.srt) subtitle files are supported for burning and adding soft tracks.
Which video formats can I use?
MP4, MOV, AVI, MKV, and WebM are supported as input. Output is always MP4.
Can I extract subtitles from a video?
Yes. If your video file contains an embedded subtitle track, use the Extract Subtitles mode to save it as an SRT file.
Will burning subtitles affect quality?
The video is re-encoded to burn in subtitles. Quality loss is minimal as FFmpeg uses high-quality settings.
