If you feel it difficult with professional tools to generate sketches of any photograph like yours, Sketch Generator is the right tool for you. Its online image processing utility will generate a “sketch”-like the 
abstraction of your digital photograph.
Just upload any file of yours, and it generates the sketch in few seconds. Not only this, you can specify.
- Sketch Resolution
- Sensitivity Threshold
- Colors
The sketch resolution allows you to define the resolution of the image. A very high-resolution picture works best. On the other hand, Sensitivity thresh hold allows you to define the detail that will be sketched: the lower the number, the more dense and detailed the sketch.
In case you don’t want a black and white sketch to add some RGB color codes to it, and the sketch will be generated accordingly.
