Below are answers to common questions about the HTML-based image enhancement tool:

1. How does this image enhancer work?

• All image processing happens directly in your browser using JavaScript Canvas API
• No server uploads – your images never leave your device
• Uses pixel manipulation algorithms for adjustments (brightness, contrast, etc.)

2. What image formats are supported?

• Input: JPG, PNG, WEBP (max 5MB)
• Output: JPG, PNG, or WEBP format
• Quality adjustable for JPG/WEBP (10-100%)

3. What editing tools are available?

• Basic adjustments:
  • Brightness (-100% to +100%)
  • Contrast (-100% to +100%)
  • Saturation (-100% to +100%)
  • Sharpness (0-100%)
• Transformations:
  • Rotation (90° increments)
  • Flip horizontal/vertical
  • Resize with aspect ratio lock
• Presets: Auto, Vibrant, Portrait, B&W

4. Why can’t I process large images?

• Browser memory limitations restrict processing to images ≤5MB
• Larger images may cause browser slowdowns or crashes
• Solution: Compress images before uploading

5. How does the privacy protection work?

• Zero server communication – all processing is local
• Images are cleared from memory when:
  • You close the tab
  • Upload a new image
  • Refresh the page
• No tracking cookies or analytics

6. Why is my edited image blurry?

Common causes:

• Excessive sharpening creates artifacts
• Extreme brightness/contrast adjustments
• Significant enlargement beyond original dimensions
  Tip: Use moderate adjustments and maintain original size when possible

7. Can I undo changes?

• Full reset: “Reset” button restores original settings
• Step undo: Not currently implemented
• Workaround: Reload page to start over

8. Mobile device limitations:

• Processing may be slower on older devices
• Max image size reduced to 3MB on mobile browsers
• Complex operations (sharpness, large resizes) may freeze the page

9. Browser compatibility:

• Fully supported: Chrome, Firefox, Edge (latest versions)
