When to use this
Use this when indoor lights turn a photo orange, shade turns it blue, or you want a warmer or cooler mood before you share it. The pixels stay the same size. Only the colour balance changes.
The slider shifts warmth. Zero leaves the picture as it is, apart from the format you save. A high setting pushes reds and pulls blues back, so skin and rooms look warmer. A low setting does the opposite, so shade and screens look cooler. Stop when the colour looks right.
This changes the whole photo. It does not fix one object and leave the rest. If the hue is right but the colour is too loud or too quiet, use saturation. If the photo is too dark, use brightness.
JPG cannot store a clear background. If the source has empty pixels, a JPG fills them with white when you save. Keep PNG when you still need those pixels clear. WebP can keep them too.
After the change, compress if the file is still heavy, or adjust saturation if the balance is right and the colours are still flat.
How to do it
- Drop one image or a batch. Files stay on this device.
- Move the slider right to warm the photo, or left to cool it. Zero leaves the picture as it is.
- When you download, pick JPG, PNG, or WebP, and set the quality if you are not saving PNG.
- Apply, then download each file or a zip of the batch.
Tips
- A small move right takes the blue out of a window-lit face. A small move left takes the orange out of a lamp-lit room.
- Zero keeps the colour balance and only changes the file format.
- JPG fills clear pixels with white. Use PNG if you still need transparency.
- Quality around 0.92 is a good balance for JPG and WebP.
