Image to CSS Gradient samples colours along an axis of your photo and produces a gradient that echoes it — linear, radial or a multi-layer mesh — with the CSS ready to paste. A gradient background costs no bandwidth, scales to any size and never blocks rendering, which is why it makes such a good placeholder.
A gradient that echoes an image is a background that costs nothing. It is what sits behind a hero while the photograph loads, what fills the space around a product shot, and what a card uses when the real image would be too heavy.
The colours are sampled from the image along an axis you choose, so the gradient follows the picture rather than merely borrowing from it. Linear, radial and a multi-layer mesh are all produced, along with the CSS for each. The mesh is the interesting one: several overlapping radial gradients positioned where the image is strongest, which reads far more like the original than any two-stop linear can.
Several overlapping radial gradients positioned where the image is strongest, which reads far closer to the original than a two-stop linear.
The stops follow the picture rather than merely borrowing its colours, so the direction matches too.
Linear, radial and mesh all generated, so you can compare and take whichever suits.
The output is CSS, so it costs nothing to load and scales to any size without a second request.
Three to five is usually right, and the CSS size for each is shown so the trade is visible.
Photographs with a clear colour direction work best.
Linear follows an axis, radial spreads from a point, mesh layers several.
Three to five stops is enough for a background; more just adds bytes.
Paste it straight into a stylesheet — no image request needed.
Because it costs no bandwidth, scales to any size, and never blocks rendering. It is ideal as a placeholder while the real image loads, or as a background where the photo itself is not needed.
Several overlapping radial gradients layered together, which produces the soft, multi-directional colour blends a single linear gradient cannot. It is more CSS but far closer to the original image.
Three to five. Two is often too flat to echo the image, and beyond about six the extra stops add bytes without adding anything visible.
It will share its colours and their rough distribution, not its content. That is enough for a placeholder or a background, and is the point rather than a limitation.
