How the online image editor works

What this online image editor can do
This online image editor focuses on the three adjustments that fix most photos: brightness, contrast and saturation. Drag a slider and the preview updates live, so you can judge the result before you export anything.
The edits are applied when you export, so the downloaded image contains them. The tool sticks to those three adjustments, which keeps it fast and simple. For a black-and-white look, use the Grayscale Image Converter; to reduce the file size afterward, use the Image Compressor; and to read a color value from your edited photo, use the Image Color Picker.
Frequently asked questions
Are the sliders non-destructive?
Yes, until you click Apply — reset at any time before that to start over.
Can I stack multiple edits?
Click Apply, then continue adjusting the sliders again on the new result.
Does this support curves or selective color?
Not yet — only global brightness, contrast and saturation are available.
Is my image uploaded anywhere?
No. The adjustments are applied with your browser's canvas, so the image never leaves your device.
What can I adjust?
Brightness, contrast and saturation, each with a live preview. All three start at 100%, which leaves the image unchanged.
