XnSketch is an easy-to-use graphics application whose main purpose is artistic stylization and retouching of digital images.
XnSketch features
The program has an intuitive interface that allows you to perform all the available actions without any special knowledge or skills.
XnSketch supports a number of common artistic techniques that make it possible to stylize digital images to look like a pencil drawing, watercolor, or oil painting.
XnSketch allows the user to adjust the brightness, contrast and saturation of digital images. All of the applied adjustments are made in real time, allowing the effect on the digital image or photograph to be seen immediately.
The program has over twenty different filters and special effects: charcoal sketches, etchings, pastel crayons, etc.
Each filter or special effect has an additional "fine-tuning option" that allows the user to easily adjust such parameters as: borders, transparency, shape, blur, etc.
The XnSketch application also knows how to work with almost all popular graphic formats. After editing, the digital image can be saved in .jpg or .png file format.
You can either upload the images directly to popular websites ( Tumblr, Facebook, Imgur, Flicker, ImageShack, etc.) or send them via email.
XnSketch is a free application that is compatible with Windows, macOS, and Linux.
