Frequently Asked Questions
What is edge sharpen?
Edge sharpen is a technique that detects edges in an image and selectively enhances them. It's different from regular sharpening as it focuses only on edges and transitions, preserving smooth areas.
Which edge detection method should I use?
Sobel is good for general use with balanced results. Canny provides precise edge detection with optimal thresholds. Laplacian is best for enhancing fine details and textures.
What does the threshold control do?
Threshold determines how different a pixel must be from its surroundings to be considered an edge. Lower thresholds detect more edges (including subtle ones), while higher thresholds only detect strong, obvious edges.
What is edge boost?
Edge boost selectively enhances only the detected edges while leaving flat areas unchanged. This creates more natural-looking sharpening compared to global sharpening methods.
When should I use the Emboss style?
The Emboss style creates a 3D effect by simulating light and shadow on edges. Use it for artistic effects or when you want to add depth and dimension to flat images.
What's the difference between color modes?
Grayscale processes edges in black and white for pure edge detection. RGB processes all color channels. Luminance uses only brightness information, while Chrominance focuses on color transitions.
How does adaptive mode work?
Adaptive mode automatically adjusts the sharpening strength based on edge characteristics. It applies stronger sharpening to well-defined edges and gentler enhancement to subtle transitions.
Can edge sharpen help with blurry photos?
Yes, edge sharpen can help recover detail in slightly blurry photos by enhancing existing edges. However, it cannot recover detail that's completely lost due to severe blur or low resolution.
Is it safe to use this edge sharpen tool?
Absolutely. All processing happens directly in your browser using JavaScript. Your photos are never uploaded to our servers, ensuring complete privacy and security.
What image formats are supported?
We support all major image formats including JPEG, PNG, WebP, HEIC, AVIF, and GIF. Images are processed at their original resolution to maintain quality.
