Online Linear Gradient Image Generator

Online Linear Gradient Image Generator

Create a two-colour linear gradient PNG. Choose dimensions, angle, scale and optional endpoint transparency; generate locally and download.

Direction is measured clockwise from the right: 0° runs left to right, 90° top to bottom, 180° right to left and 270° bottom to top. The default 135° runs from the upper right toward the lower left. The transition is centred on the canvas. At 100% scale, its span covers the rectangle’s projection onto that direction; on non-square canvases it is not simply the line between opposite corners. At 200%, the transition occupies the middle half of that span, with the first colour on one outer side and the second on the other. At 50%, the image shows only the middle part of a longer transition, so neither endpoint colour need be reached. No repetition occurs.

With transparency enabled, 25% transparency produces alpha 0.75 and 100% produces alpha 0. The tool creates exactly two color stops at positions 0 and 1; there are no extra stops, repeating mode, color-space selector, dithering option, texture or uploaded image.
