Understanding Image Formats

JPG/JPEG: The most widely used image format for photographs and complex images. JPG uses lossy compression, making files smaller but potentially reducing quality. Ideal for web use, social media, and email attachments. Does not support transparency.

PNG: A lossless format that preserves image quality perfectly. Supports transparency, making it ideal for logos, graphics with text, and images requiring a transparent background. Generally larger file sizes than JPG but maintains superior quality.

WebP: Google's modern image format offering superior compression for both lossy and lossless modes. WebP images are typically 25-35% smaller than JPG at equivalent quality. Supports transparency like PNG. Excellent for modern websites but older browsers may have limited support.

BMP: An uncompressed bitmap format that produces very large files but maintains perfect quality. Rarely used for web applications but still common in Windows applications and some professional workflows.

GIF: Limited to 256 colors, making it unsuitable for photographs but perfect for simple graphics and animations. Supports transparency and is universally supported across all platforms.

Tips for Optimal Image Conversion

Get the best results from your image conversions with these professional tips:

• For photographs, use JPG with 80-90% quality for best size-to-quality ratio
• For logos and graphics with text, prefer PNG to maintain sharpness
• Use WebP for modern websites to reduce bandwidth and improve loading times
• When converting to JPG, start with 90% quality and reduce only if file size is critical
• PNG is best for images requiring transparency or when lossless quality is essential
• Batch convert all images at once to save time on large projects
• Always keep original files as backup before converting to lossy formats
