Add Subtitles: FAQ
What is the difference between burned-in and soft subtitles?
Burned-in subtitles are part of the picture and always visible (best for social media). Soft subtitles are a separate track viewers can turn on or off.
Is it private?
Yes. Everything runs in your browser using FFmpeg compiled to WebAssembly. Your files are never uploaded to our servers.
Is it free?
Yes, free with no watermark and no sign-up. Pro adds extras like 4K export, unlimited batch and AI subtitles.
