About this tool
Adjust image brightness and contrast with real-time preview. The brightness slider ranges from 10% (very dark) to 200% (very bright), with 100% being the original. The contrast adjustment works in tandem with brightness for balanced results. Use it for fixing underexposed or overexposed photos, enhancing visibility of details, preparing images for print, and creating high-contrast artistic effects. Uses CSS filter functions through Canvas for efficient processing.
