    How it works

    1. Add your video — drag it in or browse. It stays on your device; nothing uploads.
    2. Add your .srt file — we validate it instantly and count the caption cues for you.
    3. Pick a style — font size, top/bottom position, edge margin, and a background box for readability.
    4. Burn — the subtitle text is permanently drawn into every frame with ffmpeg, right in your browser, and you download the finished MP4.
