Format Conversion Best Practices

Lossy to Lossless: Converting JPG to PNG won't recover lost quality from JPG compression
Transparency: JPG doesn't support transparency - use -background and -flatten when converting from PNG
Quality Settings: Always specify -quality when converting to lossy formats (JPG, WebP)
Color Profiles: Use -strip to remove color profiles that may cause color shifts
File Size: PNG is larger than JPG but lossless - choose based on your needs

Why Use ImageMagick for Format Conversion?

Its command-line interface enables automation and batch processing, making it ideal for workflows involving hundreds or thousands of images. Unlike online converters, ImageMagick processes images locally, keeping your files private and secure.
