Local Playback FAQ
Is it safe to play private videos?
Yes, absolutely. OnlinePlayer is designed with a 'Zero-Upload' policy. Your files are read by the browser locally and never transmitted over the network.
Can I use it offline?
Yes. OnlinePlayer is a Progressive Web App (PWA). Once you've visited it once, it works offline.
Is it better than my default player?
It often is! We support more formats (like MKV with subtitles) and features (like speed control and audio boost) that basic system players lack.
Does it drain my battery?
We use hardware acceleration where possible for efficiency. However, decoding complex formats like HEVC via software (if hardware unsupported) might use more power.
Can I load subtitles?
Yes, simply drag a subtitle file (SRT, VTT, ASS) onto the video while it's playing to load it.
