darken.video

You get home, open the clip from the beach or the ski slope, and the whole thing is washed out. Turning down brightness alone tends to leave a grey, flat picture. darken.video's Auto fix works in a different order. As the site describes it, the tool pulls the highlights back first and then sets exposure, contrast and blacks, so the clip gets darker while keeping some depth. A Strength control scales the correction up or down.

The team behind darken.video says overexposed phone and action-camera clips are hard to rescue without a full editor, and that quick apps tend to upload the video or add a watermark. Their answer was a free browser tab that brings back highlights and mood while the footage stays on the device.

Beside Auto fix are five ready-made looks. Four are Overexposed, Bright sunlight, Blown-out sky and Dim it down, and the fifth, Day for night, is the unusual one. It makes a daylight shot read as moonlit by darkening the picture by more than a stop and a half, draining most of the colour and adding a blue tint with a soft vignette. The FAQ adds that it's most convincing on shots without a bright sky in the frame.

To check your work, choose Split under Compare and drag the divider to see before and after side by side. When it looks right you export a video, and the audio track is copied across unchanged unless you switch off Keep sound.

MP4, MOV, WebM and MKV files from phones, cameras and screen recorders all open. Photos do too. A JPEG, PNG, WebP or iPhone HEIC picture opens in the same editor with the same looks.

The about page has a section titled What it can't do, and the team is plain about it. The tool can only recover detail that is still in the file. If part of the picture was recorded as pure white, the detail was never stored and no tool can bring it back. The Levels graph shows how much of a frame is clipped. One correction also applies to the whole clip. There are no masks or keyframes, so you can't darken only the sky or change the setting halfway through. And any change to the picture means the video is encoded again.

It's free, with no account, trial or logo burned into the video, and you can export as often as you like. It runs in current versions of Safari, Chrome, Edge and Firefox on phones and desktop.

On privacy, the notice last changed November 6, 2026 states that darken.video never has a copy of your video or photo. The file is read from your device and darkened there. Google Analytics is used and can be turned off, a choice the site remembers in your browser. No person or company is named as the operator. If you have a too-bright clip sitting on your phone, it costs nothing to open it here and drag the divider across.
