Understanding the Adjustments
Brightness
Controls overall lightness. 100% is original. Increase for brighter images, decrease for darker. Range: 0-200%.
Contrast
Adjusts difference between light and dark areas. Higher contrast creates more dramatic images with deeper blacks and brighter whites.
Saturation
Controls color intensity. 0% is grayscale, 100% is original, 200% is highly vibrant. Great for making colors pop.
Sharpen
Enhances edge definition for crisper details. Use moderately - too much sharpening can create artifacts.
Temperature
Shifts colors warmer (positive, yellow/orange tones) or cooler (negative, blue tones). Perfect for mood adjustment.

Frequently Asked Questions
Is my image data secure?
Yes, absolutely. All processing happens in your browser. Your images never leave your device - they are not uploaded to any server. This ensures complete privacy and security.
What is the maximum file size?
The image enhancer supports files up to 10MB. For larger files, consider resizing your image first using an image resizer tool.
Can I undo my changes?
Yes! Click the Reset button to restore all adjustments to their default values. You can also manually adjust any slider back to its original position.
Why might sharpen processing be slow?
Sharpening requires pixel-by-pixel processing which is computationally intensive. For very large images, this may take a moment. The other adjustments use optimized CSS filters and are instant.
What browsers are supported?
This tool works in all modern browsers including Chrome, Firefox, Safari, and Edge. It requires JavaScript to be enabled.
