This image color editor puts the five adjustments every photo needs on one panel: saturation, colour temperature, hue, brightness and contrast. Drag a slider and the picture updates as you move; a Reset link appears beside any value you have changed, Reset all takes the whole panel back, and holding the compare button shows the original under your finger. It is colour editing and colour adjusting for the pictures that come out of a phone or a camera not quite right: a listing photo that came out dull, a portrait shot under yellow bulbs, a screenshot that needs more punch, a product picture whose red should be the brand's red, a photo whose colour you simply want to change. Each slider uses the same arithmetic as its single-purpose page, so a picture adjusted here matches one taken through the Change Saturation, Color Temperature, Hue, Change Brightness and Contrast pages in turn.
Auto is the photo color correction button. It measures the picture and moves the sliders for you: the temperature is solved so that the average of the image comes out neutral (the grey world rule every camera's auto white balance starts from), and brightness and contrast are solved so the darkest half percent of the pixels lands at black and the brightest half percent at white. Nothing is hidden in a separate correction: the sliders show exactly what Auto did, so you can pull any of them back, push one further, or reset the lot. On a sunset or a picture that is meant to be orange, the corrector can cool it further than you want, which is why the result lands on the sliders rather than behind them. This page is the quick fix; for a three-way colour grade with wheels for the shadows, midtones and highlights, use the Color Grading tool.
Saturation scales the colour intensity, how far each colour sits from grey, about the pixel's own brightness, so lifting it makes a sky bluer without making it darker, and dragging to -100 gives an exact black and white. Temperature is a real white balance: the slider is a shift in the colour of the light the picture is rendered under, from a warm lamp to open shade, applied as a gain in linear light so black stays black instead of turning brown the way an added tint does; the details card shows the temperature in kelvin. Hue rotates every colour around the wheel by up to 180 degrees in either direction, keeping saturation and lightness where they were, so greys stay grey. Brightness is a gain, which lifts an underexposed photo the way more exposure would rather than flooding it with a milky offset. Contrast stretches or flattens every channel about mid grey. The order is the camera's: white balance first, then exposure and contrast, then colour, then hue.
The download is rendered from the original file, never from the preview, so a 24 megapixel photo comes back at 24 megapixels with every slider applied exactly as on screen. Save as PNG for a lossless copy, JPG for the smallest file or WebP for both; the format you opened is kept by default, so a JPG comes back as a JPG. On a phone the result can be shared straight to another app, and on a desktop copied to the clipboard.
Nothing is uploaded. The photo is decoded, adjusted and re-encoded inside your browser, on your own device, with no signup, no watermark and no file size limit beyond your memory. Close the tab and there is nothing anywhere to delete.
Open the photo, then drag the sliders: Saturation, Temperature and Hue change the colour, Brightness and Contrast change the light. Hold the compare button on the picture to check against the original, then press Download to save at full resolution.
Auto fixes the white balance and the exposure in one tap. It neutralises the colour cast by solving the temperature slider, and stretches the tones by solving brightness and contrast, and it moves the sliders to those values so you can see and undo every step.
Yes. Each slider is independent, and the others stay at zero until you move them. Hue rotates the colours without touching brightness or saturation; saturation changes the colour strength without changing the exposure.
No. The per-channel gains are divided by their own luma before they are applied, so warming or cooling a photo changes the colour of its light but not how bright it is.
No. Every adjustment runs in your browser and the file never leaves your device.
