Adjust the saturation of a photo without uploading it

Drop a photo, pick less color or more color, and download a new copy. Width and height stay the same. The picture stays in this tab.

Your file never leaves your device. Processed locally in your browser. Nothing is uploaded. Location and camera metadata (EXIF) are removed from the result.

Less pulls colors toward gray. More pushes the hues. Width and height stay the same. Camera location is not copied.

How to adjust saturation

1. Drop a JPG, PNG or WebP you already have. Audio and video are refused here. 2. Leave More, or pick Gray, Less or Vivid. 3. Keep the original format, or choose JPG, PNG or WebP. 4. Press “Adjust saturation” and compare the download with the original.

GustKit draws the photo on a canvas and applies the same mix as the CSS saturate filter. Gray (0%) pulls every pixel toward its brightness, so the hues go away. Vivid (200%) pushes the hues apart. 100% would leave the colors as they are, so this page starts at More. Save PNG if the photo has a clear background you need to keep.

Saturation is color strength, not brightness

Brightness and contrast move how light or dark the photo is. Grayscale removes color in one step. Sepia replaces the hues with brown. This page keeps the hues and changes how strong they are. It does not crop, rotate or resize. Camera location is not copied into the new file.

The photo stays in this tab

Nothing is sent to a server to be edited. Close the tab and the picture is gone. A photo over the megapixel limit on the page is refused, because the canvas has to hold every pixel.

How to check the color before you post the photo

1. Open the original and the download at the same zoom. 2. Look at skin and at a blue sky or a red object. More should make those hues stronger. Gray should leave them as brightness only. 3. If Vivid looks harsh, run again at More.

The pixel size does not change. Grayscale image is the page that only removes color. Brightness is a separate page. JPG quality can be lowered on purpose. Nothing is uploaded.

Frequently asked questions

Will Gray make a black and white photo?

Yes. 0% is the same idea as grayscale: each pixel becomes its brightness. Grayscale image is the page that only does that.

Does the size in pixels change?

No. Width and height stay the same. Resize image is the page that changes the pixel size.

Why do vivid colors look harsh?

200% pushes hues that were already strong until they hit the edge of what a pixel can store. Drop back to More and run again.

Is the photo uploaded?

No. The canvas in this tab does the work.

The download looks only a little richer. Did it work?

More is 150%, so the change is a step up, not a new camera. Vivid is 200% and moves the hues further.

Can I change saturation and also crop in one step?

No. Crop first, or adjust the color first, then open the other page on the download.
