Video Player Online — Play Local Videos with Pro Controls

Play videos from your device in the browser with speed control, frame stepping, A-B loop, subtitles, snapshots and 200% volume. Nothing is uploaded.

A Video Player With the Controls Pros Use

File Studio's player goes well beyond play and pause. Change speed from 0.25× to 3× for transcription or skimming, step frame by frame with the comma and full-stop keys, and set an A-B loop to repeat a single passage while you practise a guitar riff, a dance move or a language phrase. Hover the timeline to preview any moment as a thumbnail before you jump to it, and boost quiet recordings up to 200% volume.

Subtitles, Snapshots and Picture Adjustments

Drop an .srt or .vtt file on the player and subtitles appear instantly; SRT files are converted on the fly. Save any frame as a full-resolution PNG, rotate phone videos that were filmed sideways, mirror the picture, and tune brightness, contrast and saturation for dark or washed-out footage. Picture-in-picture keeps the video floating while you work in other windows.

Plays From Your Disk, Remembers Where You Stopped

Videos play straight from your device; nothing is uploaded, which matters for personal recordings, client footage and confidential meetings. Add several files to build a playlist that advances automatically, and the player remembers where you stopped in each video, so you can close the tab and pick up later.

Frequently Asked Questions

Does the video player upload my video?
No. The video plays straight from your disk through your browser's own decoder. It never leaves your device, so private recordings stay private.
Which formats can it play?
Anything your browser can decode: MP4 (H.264, and H.265 where supported), WebM (VP8, VP9, AV1), MOV and most MKV files. If a file won't play, convert it to H.264 with the Compress Video tool first.
How do I add subtitles?
Drop an .srt or .vtt file onto the player, or add it with the Add videos or subtitles button. SRT files are converted automatically. Press C to switch subtitles on or off.
Can I loop part of a video?
Yes. Press A at the start of the part you want and B at the end; the player repeats that section until you press X. It's handy for learning dance moves, music, languages or sports technique.
Are my files uploaded to a server?
No. File Studio is built on a strict local-first architecture. Every PDF operation — merging, splitting, compressing, redacting — runs entirely inside your browser using JavaScript. Your files never leave your computer. You can even disconnect your internet after the page loads and the tools will continue working perfectly.
Is File Studio completely free?
Yes, 100% free with no limits. There are no file size caps, no daily limits, no watermarks added to your output, and no account or email required. All tools are free forever.
Does it work on mobile and tablet?
Yes. File Studio is fully responsive and works on Android and iOS browsers. All processing happens locally on your phone's or tablet's hardware.
