You can adjust brightness, contrast, saturation, hue rotation, colour temperature (warm/cool), sepia tone, grayscale, sharpen, blur and invert. The adjustments are organised into three groups: Light, Color and Detail.
Most adjustments are applied losslessly during the download encode. Sharpening is applied via a pixel-level convolution which permanently modifies the pixel values. If you download as PNG or WebP lossless, there is no additional quality loss beyond the adjustments themselves. JPEG encoding at high quality (90+) is visually lossless for most images.
Temperature shifts the colour tone of the image between warm (orange/golden, positive values) and cool (blue, negative values). It simulates the effect of different lighting conditions. Moving toward warm makes the image feel like golden hour sunlight. Moving toward cool makes it feel like overcast daylight or shade.
The sharpen slider applies an unsharp mask convolution to the image on download. It enhances edges and fine detail by increasing the contrast between neighbouring pixels. It is applied using direct pixel manipulation via the Canvas API, not a CSS filter. Use it moderately — over-sharpening can create visible halos around edges.
No. All adjustments are applied in your browser using the HTML5 Canvas API and CSS filters. Your image never leaves your device.
Yes. Each slider has a Reset button that returns that specific adjustment to its default value. There is also a Reset all button in the header and footer that returns every adjustment to its default at once.
