What is the difference between burned-in and soft subtitles?

Burned-in subtitles are permanently rendered into the video frames. Soft subtitles are a separate track that can be toggled on/off.

Can I customize the subtitle appearance?

Yes. You can change font size, font color, background color, opacity, and position.

Will this reduce video quality?

Burning requires re-encoding, which may slightly affect quality. We optimize for the best possible output.

What subtitle formats are supported?

SRT and VTT are fully supported. Both are parsed and rendered on each frame.

Is my video uploaded to a server?

No. All encoding happens locally in your browser. Your files never leave your device.

Why should I burn subtitles instead of muxing them?

Burned-in subs guarantee visibility on all platforms — especially social media where players may not support soft subtitle tracks.

Burn subtitles into video

Permanently hardcode SRT or VTT subtitles into your video frames. Unlike soft subs, burned-in subtitles display on every device and player without compatibility issues.
