Getting Started
Step 1: Open the Tool
Simply open the HTML file in any modern browser (Chrome, Firefox, Safari, Edge). You’ll see:
- A black-and-white interface with a sample dog photo (this is just a demo image)
- A "Upload Image" button at the top
- A slider bar in the middle of the photo
- Three adjustment sliders below (brightness, contrast, saturation)
- Two buttons at the bottom (Reset and Download)
Step 2: Try the Sample Image First
The cute puppy photo is there to help you practice. Play with these features:
- Drag the middle slider left/right to see before/after comparison
- Move the brightness slider to make the image lighter/darker
- Adjust contrast to make details pop
- Change saturation to make colors more vibrant or muted
Key Features Explained
1. The Comparison Slider
What it does:
- Lets you swipe between original (left) and edited (right) versions
- Works like those "before/after" weight loss ads
How to use it:
- Click and drag the white circle in the middle
- Move left → See more of the original (before)
- Move right → See more of the edited version (after)
Pro tip: The labels "Before" and "After" fade in/out as you move the slider for better clarity.
2. The Three Magic Sliders
These are your editing controls below the image:
A. Brightness
- What it fixes: Dark shadows, underexposed photos
- How to use:
- Slide right → Add light (good for dark photos)
- Slide left → Darken image (fix overexposed shots)
- Ideal range: 80-120% (avoid extremes unless artistic effect wanted)
B. Contrast
- What it fixes: Flat-looking images, dull colors
How to use:
Slide right → Make dark areas darker and light areas lighter- Slide left → Reduce difference between lights/darks
- Sweet spot: 90-110% (gives depth without looking unnatural)
- C. Saturation
- What it fixes: Washed-out colors, dull landscapes
How to use:
Slide right → Boost colors (make skies bluer, grass greener)- Slide left → Create black-and-white effect
- Safe zone: 80-130% (avoid going too high for skin tones)
3. Uploading Your Own Photos
Supported formats:
- JPEG, PNG, WEBP (most common image formats)
How to upload:
Click the "Upload Image" button
Select a photo from your device
Wait 2-3 seconds – your image will appear
What happens next:
- The tool automatically applies current settings to your photo
- Use the same sliders to edit your image
- The comparison slider still works the same way
Note: Uploading doesn’t send your photos anywhere – they stay on your computer.
