raised texture
Each pixel is compared with the one to its left and the one above it, and the difference is drawn on a mid-grey ground. Where the image is flat the difference is zero and you get flat grey; where brightness climbs you get a light ridge, and where it falls you get a dark trough. The result reads as relief lit from the top left.
Because the operator only looks up and left, the lighting direction is fixed. Rotate the image 180 degrees before embossing and the ridges and troughs swap — the same trick a stamp maker uses to turn a raised seal into a sunken one.
three steps
A JPG, PNG or WebP. Sharp outlines and texture give the strongest relief; a soft, evenly lit photo comes out nearly blank grey.
The filter runs in one pass over the decoded pixels. There is nothing to tune, so the preview is the finished result.
Save as PNG. The output is mostly fine one-pixel detail on a flat ground, which is exactly what JPG compression smears first.
quick answers
The difference between each pixel and its left and top neighbours, offset onto mid grey. Flat regions land on grey, rising edges go light, falling edges go dark. It is a one-pass convolution, not a lighting simulation.
Because the source has very little local contrast. Emboss reacts to change between adjacent pixels, not to overall brightness, so a soft portrait or a gradient background gives it almost nothing to find.
No. Emboss writes the same value into red, green and blue, so the result is greyscale by construction. Run a colour grade over it afterwards if you want a tinted relief.
No — the output is fully opaque. The filter rebuilds every pixel including the alpha channel, so a transparent PNG comes back with a solid background.
Raise contrast on the source first, or upscale the image before embossing so the edges span more pixels. The filter itself has no strength setting.
Download the embossed image and feed it into adjust image or photo filters. Order matters — embossing last usually wins, because it turns everything into edges.
No. The filter runs on a canvas in your browser.
