How do I preview subtitles on a video without uploading?

This player loads your video and subtitle straight from your device using the browser — no upload, no account. Pick a video file, then an SRT or VTT file, and press play. It is the fastest way to sanity-check timing and line breaks on subtitles you just created or edited.

Which subtitle formats are supported?

SRT and VTT are supported — SRT is converted to VTT automatically for the player. ASS/SSA files will play as plain text, but their advanced styling (positioning, karaoke) is not rendered here. For full ASS styling, burn the subtitles in with the GeekLink app.

Frequently Asked Questions

Is my video uploaded anywhere?

No. The video and subtitle are loaded locally in your browser and never sent to any server.

Which subtitle formats work?

SRT and VTT. SRT is converted to VTT on the fly. ASS/SSA advanced styling is not rendered in the browser player.

Why can't the player show ASS positioning and effects?

The browser's native subtitle track supports VTT styling only. Rendering full ASS requires a dedicated renderer; for that, burn the subtitles into the video with GeekLink.
