Analyze - Check resolution, sharpness, artifacts
Enhance - Apply appropriate improvements
Optimize - Adjust for intended use case
Save - Preserve original, save enhanced version

Python Enhancement Script

from PIL import Image, ImageEnhance, ImageFilter

def enhance_image(input_path, output_path):
    img = Image.open(input_path)

    # Upscale if small
    if img.width < 1920:
        scale = 1920 / img.width
        new_size = (int(img.width * scale), int(img.height * scale))
        img = img.resize(new_size, Image.LANCZOS)

    # Sharpen
    img = img.filter(ImageFilter.SHARPEN)

    # Enhance contrast slightly
    enhancer = ImageEnhance.Contrast(img)
    img = enhancer.enhance(1.1)

    img.save(output_path, quality=95)
    return img.size

# Usage
enhance_image('screenshot.png', 'screenshot-enhanced.png')

ImageMagick Commands

# Sharpen image
convert input.png -sharpen 0x1 output.png

# Upscale 2x with good quality
convert input.png -resize 200% -filter Lanczos output.png

# Remove compression artifacts
convert input.jpg -enhance output.jpg

# Batch process folder
for f in *.png; do
    convert "$f" -sharpen 0x1 "enhanced-$f"
done

Optimization by Use Case

| Use Case | Resolution | Format | Quality | |----------|------------|--------|---------| | Web/Blog | 1920px wide | PNG/WebP | 85-95% | | Social Media | Platform-specific | JPG | 90% | | Presentations | 2560px+ | PNG | 95% | | Print | 300 DPI minimum | PNG/TIFF | 100% |

Social Media Sizes

| Platform | Recommended Size | |----------|-----------------| | Twitter | 1200x675 | | LinkedIn | 1200x627 | | Instagram | 1080x1080 | | Facebook | 1200x630 |

Tips

Always keep original files as backup
PNG for screenshots (lossless)
JPG for photos (smaller size)
WebP for web (best compression)
Batch process for multiple files

Required Tools

# Python
pip install Pillow

# ImageMagick
sudo apt-get install imagemagick

# For advanced upscaling
pip install opencv-python
