Grayscale conversion removes all color information from an image, leaving only shades of gray (from black to white). It's a common technique in photography and digital imaging for artistic expression or technical purposes.

• Creating classic black and white photos
• Artistic styling and mood setting
• Reducing visual complexity
• Preparing images for certain printing methods
• Accessibility testing (simulating color blindness)

1. Drag & drop or click 'Choose Image' to upload your photo.
2. The image with the grayscale effect applied will appear automatically.
3. Adjust the 'Strength' slider to control the intensity of the grayscale effect (0% = original color, 100% = full grayscale).
4. Click 'Download Image' to save the result as a PNG file.
5. The filename will be automatically appended with "_grayscale".
