Detailed User Guide

Step 1: Upload Your Image

Click the dropzone or drag and drop an image file (JPG, PNG, or WebP). The original image will be displayed in the preview area, and you can start adjusting immediately.

Step 2: Adjust Brightness, Contrast & Saturation

Use the three sliders to fine-tune your image:

  • Brightness (0%–200%) — Darken or brighten the image. 100% is the original brightness.
  • Contrast (0%–200%) — Reduce or increase color contrast. 100% is the original contrast.
  • Saturation (0%–300%) — Desaturate (grayscale at 0%) or boost colors. 100% is the original saturation.
Tip: Click "Apply Adjustments" after setting the sliders. The preview updates so you can see the exact effect before downloading.

Step 3: Apply & Download

Click "Apply Adjustments" to render the final result with all three adjustments combined, then click "Download" to save the adjusted image as a JPG file.

Best Use Cases

  • Fix underexposed photos — Increase brightness to recover detail in dark images
  • Make colors pop — Boost saturation for social media posts
  • Fix washed-out images — Increase contrast to add depth
  • Create B&W effects — Reduce saturation to 0% for grayscale

Pro Tips

  • For portrait photos, avoid pushing brightness above 150% — skin tones can look unnatural
  • Combine slight contrast boost (+20%) with slight saturation boost (+15%) for a quick "vibrant" look
  • If the image looks too flat after reducing contrast, try increasing saturation slightly
  • For printing, keep brightness at or below 110% to avoid washed-out prints
