Image Format Guide

JPEG/JPG: Ideal for photographs and complex images with many colors. Lossy compression reduces file size significantly.

PNG: Perfect for graphics, logos, and images requiring transparency. Lossless compression preserves image quality.

WebP: Modern web format offering 25-35% better compression than JPEG with similar quality. (Browser unsupported)

AVIF: Next-generation format with superior compression and quality. Up to 50% smaller than JPEG. (Browser unsupported)

BMP: Uncompressed bitmap format. Large file sizes but universal compatibility.

ICO: Multi-resolution icon format for applications and websites (16px-48px sizes).

TIFF: High-quality format for professional use. Converted to PNG due to browser limitations.

JPEG/JPG - The Photography Standard

JPEG remains the gold standard for photographic content due to its excellent compression algorithms that can reduce file sizes by 90% while maintaining acceptable quality. The format uses discrete cosine transform (DCT) to analyze image data and remove information less noticeable to human eyes.

When to use: Digital photography, web images with complex colors, social media uploads, email attachments, and any scenario where file size matters more than perfect quality retention.

PNG - Lossless Precision

PNG (Portable Network Graphics) was designed as a patent-free replacement for GIF, offering lossless compression and full alpha channel transparency. It excels at preserving sharp edges, text, and graphics with precise color reproduction.

When to use: Logos, icons, screenshots, graphics with text, images requiring transparency, and any content where quality cannot be compromised.

WebP - Modern Web Optimization

Developed by Google, WebP provides 25-35% better compression than JPEG while supporting transparency like PNG. It offers both lossy and lossless compression modes, making it ideal for modern web applications focused on performance.

When to use: Progressive web apps, mobile-first websites, performance-critical applications, and modern web development where Core Web Vitals scores matter.

AVIF - Next-Generation Excellence

AVIF (AV1 Image File Format) represents the cutting edge of image compression technology. Based on the AV1 video codec, it can achieve file sizes 50% smaller than JPEG while maintaining superior quality, supporting HDR and wide color gamuts.

When to use: Future-focused web development, high-end photography portfolios, applications targeting latest browsers, and scenarios demanding maximum compression efficiency.
