Why Convert Between JPG, PNG, and WebP?

Each image format has its strengths. Here's when to convert between them:

JPG to PNG — When you need transparency (alpha channel) for logos, icons, or overlays
PNG to JPG — To reduce file size for photographs and web images where transparency isn't needed
JPG to WebP — For 25-35% smaller file sizes with the same visual quality
PNG to WebP — Maintains transparency while reducing file size by 26% on average
WebP to PNG — For maximum compatibility with older browsers and image editors

JPG vs PNG vs WebP: Which Should You Use?

JPG/JPEG — Best for photographs. Lossy compression, no transparency support, widely compatible.
PNG — Best for graphics, screenshots, and images needing transparency. Lossless compression, larger file sizes.
WebP — Best for modern web. Superior compression (25-35% smaller than JPG/PNG), supports transparency and animation.
GIF — Use only for simple animations. Limited to 256 colors, poor compression.
BMP — Avoid unless required by specific software. Uncompressed, very large files.
