Make a video brighter or darker, add contrast, boost or mute the colors, adjust gamma and make it warmer or colder. Or apply a ready filter: black and white, sepia, vintage or vivid. A before/after preview shows the result on a still. The video never leaves your browser.

How it works

  1. Choose an MP4, MOV, WebM, MKV or AVI or drag it onto the page.
  2. Pick a filter or move the sliders; compare before and after on the still.
  3. Click Apply colors and download the video — the sound stays as it was.

Frequently asked questions

Is the preview exactly what I get?

Almost: the preview uses the same color math as the final video, but on a smaller copy of one frame, so tiny differences are possible. Move the Frame slider to check dark and bright scenes.

Does the quality or the sound change?

The picture is re-encoded with the quality you choose in the settings; the sound is copied unchanged when the format stays the same. Tick “Remove audio” for a silent video.

Is it free?

Yes. All tools are free, with no sign-up and no watermarks.

Are my files uploaded to a server?

No. Everything runs in your browser, so your files never leave your device.
