Small adjustments (10-20 percent) often produce the most natural-looking results.
Over-brightening can wash out colors. Increase contrast to compensate if needed.
High saturation looks unnatural on skin tones. Use moderate values for portraits.
Adjust brightness first, then fine-tune contrast and saturation for best results.
Will the image quality change?
The pixel values are modified, but the resolution and format remain the same. Extreme adjustments may introduce artifacts.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API. The image never leaves your device.
What image formats are supported?
The tool supports JPG, PNG, WebP, and GIF images.
Can I reset to the original?
Yes. Reset the sliders to their default values to restore the original appearance.
Can I process multiple images at once?
Yes. Upload multiple files and the tool applies the same adjustments to all of them.
