Why Burn Subtitles Instead of Embedding Them

Universal Compatibility

Hardcoded subtitles show on every player and device — including WhatsApp, TikTok, and smart TVs — without needing to load a separate SRT file.

Social Media Auto-Play

Videos auto-play silently on most social platforms. Burned-in subtitles are visible even with sound off, dramatically increasing viewer retention.

Accessibility

Permanently embedded subtitles ensure deaf and hard-of-hearing viewers see captions regardless of which player or platform is used to watch the video.

Why Burn Subtitles Offline?

Private

Your video and subtitle file never leave your device. No upload, no server, no data collection.

Fast

FFmpeg.wasm renders subtitles directly in your browser — no waiting for a cloud render queue.

Works Offline

Once the page loads, subtitle burning works without any internet connection.

Burn Subtitles Free — No Upload, No Registration

Runs entirely in your browser — no upload, no account, no waiting.
