Image sharpening enhances edge contrast to create the appearance of increased clarity and detail. This online sharpen tool uses an unsharp mask algorithm to detect edges and amplify local contrast, making photos appear crisper and more defined. Perfect for fixing slightly blurry photos, enhancing texture details, and preparing images for print or web display.
Upload your image and adjust the Amount slider to control sharpening intensity - lower values for subtle enhancement, higher values for dramatic sharpening. The Radius slider controls how many pixels around each edge are affected - smaller radius sharpens fine details like hair and fabric texture, larger radius enhances broader edges and overall contrast. Preview changes in real-time and download your sharpened image in PNG, JPG, or WebP format.
Apply sharpening to photos that appear slightly soft or out of focus. Use moderate sharpening for portraits to enhance eye detail while preserving skin smoothness. Apply stronger sharpening to landscape and architectural photos to bring out textures in foliage, buildings, and natural elements. Product photography benefits from sharpening to highlight material textures and fine details. Always sharpen as a final step after resizing images, as resizing can introduce softness.
Proper sharpening enhances detail without visible artifacts. Over-sharpening creates halos around edges, amplifies noise, and produces an unnatural "crunchy" appearance. Start with moderate settings and increase gradually while watching for halos - bright outlines around dark edges or dark outlines around bright edges. For noisy images, use lower amounts to avoid amplifying grain. High-quality images can handle more aggressive sharpening than compressed or low-resolution photos.
This tool processes images at full resolution, preserving maximum quality for professional results. The convolution-based sharpening algorithm provides consistent, artifact-free enhancement across the entire image. Export in PNG for lossless quality, JPG for smaller file sizes with excellent quality, or WebP for modern web optimization. Supports images up to 4096x4096 pixels for high-resolution editing.
