Image Editing.

Scales your image to exact pixel dimensions on a canvas. With the aspect-ratio lock on, typing a width computes the matching height automatically, so nothing ever stretches out of shape.

Cuts out any region with four sliders — X, Y, width and height — all in percentages, so the crop is easy to nudge precisely. The preview updates with every move.

Rotates by any angle from 0° to 345° in 15° steps. The canvas expands automatically so corners are never clipped — rotate 45° and you get a diamond on a larger canvas, nothing cut.

Mirrors the image horizontally, vertically or both with a canvas transform. Handy for fixing scanner output, creating symmetrical layouts and testing UI with reversed imagery.

A genuine pixel-level blur: a two-pass separable box blur with an adjustable radius, computed on canvas — not a CSS filter. Crank the radius for a full privacy blur or keep it low for a soft-focus look.

Applies a 3×3 convolution kernel whose strength you control: the center pixel is amplified while its neighbors are subtracted, which pushes edges back into focus. Subtle at 20%, punchy at 80%.

A linear gain on every channel, from 0% (black) through 100% (unchanged) to 200%. The fastest fix for an underexposed shot before you reach for anything heavier.

Pushes pixels away from mid-gray: below 100% flattens the image toward gray, above 100% deepens shadows and brightens highlights. The classic tool for adding punch to flat, hazy photos.

Blends every pixel toward or away from its own luminance. At 0% the image is fully grayscale; at 300% colors go hyper-vivid. Anything in between is a smooth intensity dial.

Converts to grayscale using the luminance weights the eye actually perceives (29.9% red, 58.7% green, 11.4% blue), and lets you blend from full color to full gray with the amount slider.

Applies the classic warm-tone sepia matrix — the vintage darkroom look — blended by the amount you choose, from a subtle warm cast at 30% to full antique at 100%.
