How Image to Sketch Converter Works
The sketch effect is achieved through a classic digital art technique: **Grayscale, Invert, Blur, and Color Dodge**. The tool first converts your image to grayscale, then creates an inverted copy. It then blends the original grayscale layer with the inverted layer using the Color Dodge blend mode. This entire process is performed locally in your browser using the Canvas API, ensuring maximum speed and privacy.
- ✔️ **Upload:** Upload your JPG or PNG image.
- ✔️ **Adjust Blur:** The blur radius controls the thickness and softness of the sketch lines.
- ✔️ **Convert:** The tool applies the complex pixel manipulation algorithm.
- ✔️ **Download:** Save the final sketch as a high-quality PNG file.
- ✔️ **Private & Free:** All processing is done locally on your device—your image is never uploaded to a server.
