Adding colour noise at low opacity with overlay blend mode is a classic digital art trick. It adds subtle texture and colour variation that makes artwork feel more organic and cohesive, similar to the natural grain in traditional media.
Artwork Enhancer applies the classic low-opacity colour noise overlay that illustrators use to soften banding and add organic texture to digital paintings, comic panels, vector art, or AI-generated images. You drop in a PNG or JPG, adjust two sliders, and download a PNG with the noise baked in. Everything runs locally in a canvas; no upload happens.
The drop area accepts a single image at a time and gives you three ways to bring it in.
Two sliders control how the noise layer is generated and blended. The preview re-renders whenever you change them.
The Download button saves the current preview as a PNG. The exported size matches the original image dimensions, shown beneath the preview, so you can drop the file straight back into your project.
It draws a layer of randomly coloured pixels on top of your image and blends it with the overlay mode. Flat colour areas pick up subtle variation, soft gradients gain texture, and the result feels less plastic without changing the underlying drawing.
Around 2 percent matches how illustrators usually apply this trick in Photoshop or Procreate. Anything higher tends to look like a deliberate grain effect rather than a finishing pass.
No. The image is read with FileReader, processed in a canvas in your browser, and the PNG download is generated locally. Nothing leaves your device.
At 1x every pixel gets its own random colour. Higher values draw smaller noise then scale it up with nearest-neighbour, so the noise becomes blockier and more visible. Use it when you want a deliberate texture instead of a fine grain.
