Image effects
Apply photographic and stylistic effects to images on demand. Convert to grayscale, reduce to pure black-and-white (threshold / 1-bit / monochrome), soften with Gaussian blur, sharpen edges, render charcoal-style sketches, or shift brightness, saturation, and hue. Every effect runs through the ImageMagick engine and outputs in the format you sent — no client-side image library required.
Auto-enhance
Apply a sensible-default tonal correction (auto-levels + auto-contrast).
CLAHE (adaptive histogram equalize)
Apply CLAHE (contrast-limited adaptive histogram equalisation) to an image.
Edge detect (Canny)
Detect edges in an image (Canny edge detection).
Image blur
Apply a Gaussian blur to an image.
Image charcoal
Apply a charcoal-sketch effect to an image.
Image color replace
Replace one colour in an image with another.
Image grayscale
Convert an image to greyscale using a configurable luminance method.
Image modulate
Adjust hue, saturation, and brightness in one pass.
Image pixelate
Pixelate an image (mosaic effect).
Image quantize
Reduce an image to a fixed colour palette.
Image sepia
Apply a sepia tone to an image.
Image sharpen
Sharpen an image (unsharp mask).
Image threshold
Convert an image to pure black-and-white using a brightness threshold.
