Video Player

The Video Player plays video files stored on your own device. Select a few videos, and they appear in a playlist on the page. Click any entry to watch it, and switch speed between 0.5x and 2x. It relies on your browser's built-in video support, so whether a particular file plays depends on whether the browser understands that file's container and codec, not on this page. It supplies no videos, does no format conversion and does not remember your playlist.

How to use it

1. Click the dashed area "Click to select video files (multiple allowed)" and choose one or more video files. You can click again later to add more; new videos go to the end of the list.
2. After the first files are added, the first video is selected and shown in the player. Press play to start; it does not start by itself.
3. In the "Playlist" section, click any row to switch to that video. The current one is highlighted. Click the X at the end of a row to remove it.
4. Use the player's own control bar to pause, seek, change volume or go fullscreen.
5. The "Speed" row offers 0.5x, 0.75x, 1x, 1.25x, 1.5x and 2x. Click one to switch.
6. Tick "Auto-play next" above the playlist (off by default) and, when the current video ends, the player switches to the next entry in the list and starts playing it. It stops after the last video and does not go back to the start.
7. If a file cannot be played, the player is replaced by a notice explaining that the format or codec is most likely unsupported, and suggesting you convert it with the "Video Format Converter" tool first.

A practical scenario

Say you filmed several lecture recordings and want to skim them on your computer without installing a player. Select them all and open each one from the playlist. Use 1.5x or 2x to move through the slow parts, and 0.75x where you need to see details. If one of the files is an older AVI or WMV and the page reports it cannot be played, follow the suggestion: convert it to MP4 in the Video Format Converter and come back. The files are not uploaded anywhere during any of this.

Supported range and known limits

• The file picker accepts any video type, but what actually plays is decided by your browser. MP4 (H.264) and WebM are the safest. AVI, WMV, FLV, some MKV files and MOV files with unusual codecs often fail, and sometimes you get sound without picture or the reverse, depending on the specific codecs.
• Auto-play next is off by default: tick "Auto-play next" and the next entry starts when one ends. It only moves forward and stops at the end of the list (no list looping); some browsers' autoplay policies may block it or require you to press play.
• There is no subtitle loading, picture-in-picture control, screenshot function or loop switch beyond what the browser's own controls provide.
• The playlist is held only in the page's memory. It is cleared when you refresh or close the page, and you must add the files again.
• Known limitation: after you remove the video that is currently playing, nothing in the list is selected until you click an entry again.
• Very large files or high-bitrate 4K video may stutter on modest hardware. That is a limit of the device's decoding ability, not of this tool.

FAQ: Why won't some videos open?

A video file consists of a container (such as .mp4 or .mkv) and the codecs inside it (such as H.264, H.265 or VP9). The browser has to support both. Two .mp4 files can behave differently if one holds a codec the browser lacks, for example H.265 recorded by some devices. When that happens the page shows a notice, and converting the file to MP4 (H.264) or WebM with the Video Format Converter usually fixes it.

FAQ: Why are there only six speeds?

The speeds are fixed in the page: 0.5x, 0.75x, 1x, 1.25x, 1.5x and 2x. They cover the usual needs for slowing down or speeding up. If you need finer control, a dedicated desktop player is a better fit.

FAQ: Are my videos uploaded?

No. For each video the page creates a temporary link that only works in your own browser and hands it to the player, so the data stays on your device. The tool has no feature for sending files to a server and does not require an account. The links are released when you leave the page.

FAQ: Does it work on a phone?

Yes, a mobile browser can pick a local video and play it. Phone browsers often take over for fullscreen playback, and some systems restrict autoplay and background playback, so the exact behaviour depends on your system and browser.

Privacy and how files are processed

Videos are played only inside your browser and are never uploaded. The chosen files are passed to the player through temporary local links, without going through any server, and the tool does not keep a record of what you watch. Refreshing or closing the page clears the playlist and the links.
