The emboss effect turns an image into a grey relief that looks as if it were stamped into metal or stone. Along the edges, light and dark seams appear that fake depth, while even areas become a neutral mid-grey. The result emphasises contours and texture rather than colour.
Embossing is useful for artistic effects, background textures, logos with a relief look, or to reveal the edge structure of a photo. Because the effect works on brightness, the original colour disappears and a graphic greyscale relief remains. The output keeps your original format and dimensions.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. A classic 3x3 emboss kernel with a mid-grey offset is used, so flat areas turn exactly grey. Animated images are flattened to a single frame.

Limitations: Applies a 3x3 emboss kernel with a mid-grey offset to the luminance, so edges appear as light and dark seams and flat areas turn mid-grey; the result is a greyscale relief (R==G==B). The original format and dimensions are preserved (PNG keeps transparency; JPEG flattens onto white). Animated inputs are reduced to a single frame.
No. The effect runs entirely locally in the browser on a canvas - even offline. Your image never leaves your device.
Embossing emphasises edges via brightness differences and applies a mid-grey offset; the original colour is intentionally lost.
For a relief look, textures, artistic effects, and to highlight the edge structure of an image.
Yes. A PNG stays a PNG (with transparency), a JPEG stays a JPEG, and the dimensions are unchanged.
