Image Format Comparison

• PNG (Portable Network Graphics): Lossless compression, supports transparency, best for logos, graphics, screenshots. Larger file sizes but perfect quality. Ideal for: icons, illustrations, text images, transparent backgrounds.
• JPG/JPEG (Joint Photographic Experts Group): Lossy compression, no transparency, best for photographs. Smallest file sizes with good quality at 80-90%. Ideal for: photos, complex images, web galleries, email attachments.
• WebP (Web Picture Format): Modern format with superior compression—30% smaller than JPG with same quality. Supports transparency and animation. Ideal for: modern websites, web optimization, fast-loading pages. Not supported in very old browsers.
• BMP (Bitmap): Uncompressed format, very large files, perfect quality, Windows native. No compression means huge files. Ideal for: Windows applications, editing without quality loss, archival storage.
• GIF (Graphics Interchange Format): Limited to 256 colors, supports animation and transparency, best for simple graphics and animations. Ideal for: animated images, simple icons, memes.
