Adjust Images Online

Is your photo a little dark, flat or too harsh? Choose an image, try a preset or adjust individual sliders, then compare it with the original before downloading. Undo lets you try another balance.

Adjust an image in 3 steps

01

Choose one image

Choose a JPG, PNG or WebP, or try a sample to explore the sliders.

Choose the adjustment that fits your image

Start with a small change, compare it with Original, then refine it. A preset is a starting point; you can still change the six sliders afterward.

SituationTry in the toolCheck
Image is dark or too brightAdjust Exposure for the whole image, then fine-tune with Brightness.Inspect highlights and shadows; detail missing from the source cannot be restored.
Colors look flat or tintedAdjust Saturation and Temperature; add a little Contrast if the image still looks flat.Compare skin, white backgrounds or product colors with the original to avoid an overly strong tint.
Edges look slightly softRaise Sharpness moderately and inspect text or fine edges.If halos or noise become visible, lower the slider; it cannot recover lost detail.

How do the preview and download differ?

The preview is limited to a 1,400 px long edge for editing. Export starts again from the source and keeps up to 4,096 px on the long edge; larger images are reduced. Open the download to check its pixels and detail.

Choose PNG, JPG or WebP?

PNG is the default and does not use the Quality slider. JPG and WebP allow 60–100% quality; check size and clarity after downloading. For transparent images, prefer PNG or WebP and inspect the background; JPG does not preserve transparency. Source metadata may not carry over to the new file.

If the result needs another pass

Light or color looks too strong
Compare with Original, lower the sliders one at a time or use Undo. Presets do not lock the sliders.
The download has fewer pixels than the source
The downloaded file has a 4,096 px long-edge limit. For a specific pixel size, use Image Resizer.
The image will not open or export
Try another JPG, PNG or WebP under 20 MB and 30 MP. If JPG or WebP export fails, try PNG or a smaller image; large files may run out of memory.

Where is the image processed?

The image is read, adjusted and exported in your browser; this workflow does not send the file content to an KitoTool processing API. The page still has general analytics. The source file on your device is not changed.
