    How it works

    1. Add your images

      Choose up to 10 images — JPG, PNG, WebP, GIF, BMP, AVIF or HEIC — straight from your device.

    2. Tune the effect

      Move the lightness slider until the mood feels right; hues stay natural.

    3. Download the result

      Preview each filtered copy, then save them one by one or all together as a ZIP.

    Lighten without washing out

    Lightness lifts colors toward white along a natural scale instead of just adding white to everything. Skin tones and skies stay believable while shadows open up and show detail.

    Use positive values for gloomy interiors and heavy scans, and negative values to deepen a bright picture into evening mood. Hues shift far less than with plain brightness.

    How it differs from brightness

    Brightness adds the same fixed amount to every pixel, which can bleach colors. Lightness respects how eyes see color, so saturated reds and blues survive the lift.

    Mid-range photos respond best, since nearly white images have nowhere left to go. Combine with a touch of saturation afterwards to keep lifted colors lively.

    Kept on your machine

    Your pictures are lightened by scripts running locally, not by a remote service. The bytes travel from your disk to your screen and back, never touching a network cable.

    There are no accounts to create and no watermarks added. Process up to ten images per batch and download them with clear, familiar file names.

    Questions

    Are my images uploaded when I use this?

    No. Everything runs inside your browser on your own device. Your files are never sent to us or to anyone else.

    How is this different from brightness?

    Brightness adds the same fixed amount to every pixel, while lightness moves colors along a natural scale toward white or black, keeping hues believable.

    Will pure white areas change?

    No. Pure white cannot get any lighter, so it stays put while the rest of the image lifts around it. Use a negative amount to darken instead.

    Is it free?

    Yes. Free to use, with no sign-up, no watermark and no daily limits.
