Play MP4, MKV, WebM, MP3 and other files from your computer, straight in the browser. Nothing is uploaded. It remembers where you stopped, plays whole folders as a playlist, shows SRT/VTT subtitles, goes up to 16× speed and boosts quiet audio to 500%.
Use it as a website (installable, works offline) or as a Chrome extension. Both run the same code.
- Continue watching: your position and speed are saved for every file. The start screen shows partly watched videos with thumbnails, and in Chrome and Edge one click reopens the file, paused at the spot where you stopped.
- Playlists and folders: drop several files or a whole folder. Files play in natural order (episode 2 before episode 10) and the next one starts automatically.
- Subtitles: SRT and VTT, matched to the video by file name. You can shift the timing in 0.1 s steps and resize the text.
- Speed control: 0.1× to 16× in 0.1× steps, plus one-key presets for 1.5×, 2×, 2.5×, 3× and 4×.
- 500% volume boost for quiet recordings.
- Power tools: A-B loop, frame-by-frame stepping, full-resolution screenshots and jumping to 0–90% with the number keys.
- Smart stretch to fill: the stretch adapts to your screen and window size, leaves vertical videos alone and skips videos that would be distorted too much. Crop-to-fill and arrow-key fine-tuning are there too.
- Settings: choose which buttons appear on the player (hide subtitles, playlist, zoom and more), plus autoplay, resume, skip amount (5/10/30 s), stretch limits and theme.
- On-screen feedback for every shortcut, and a cheat sheet that opens with ?.
- Light, dark or system theme.
- Works offline and installs as an app. Once installed, it shows up under Open with for video files on your computer.
- Integrates with your system's media controls (play/pause, skip, next/previous track).
- Album art from MP3 files is shown while the audio plays.
Open https://abduldevhub.github.io/Local-Video-Player/, then drop a video onto the page or click Choose files. To install it as an app, use Install app on the start screen (Chrome/Edge), or Add to Dock / Add to Home Screen in Safari.
It works in Chrome, Edge, Firefox and Safari. Chrome and Edge get the extras: one-click resume from Continue Watching, folder picking and Open with for the installed app.
