What is Image Sharpening

Image sharpening is a digital enhancement technique that increases the contrast between pixels along edges to make an image appear clearer and more defined. It helps bring out fine details and can compensate for slight blurriness caused by camera movement or lens limitations.

An online image sharpener is a tool that allows you to enhance the sharpness and clarity of your images without downloading specialized software. It uses convolution filters (3x3 or 5x5 matrices) to detect and enhance edges, making your photos appear more crisp and detailed.

Upload your image using the file selector or drag and drop area. Choose the convolution mask size (3x3 for subtle sharpening or 5x5 for more aggressive sharpening) and adjust the strength slider to control the intensity of the effect.
