Choosing the right image format can feel confusing, but it has a huge impact on your website's performance and visual quality. This guide will help you understand the most common formats available in Image Toolkit and when to use each one.

JPEG (Joint Photographic Experts Group)

Pros: Excellent for photos, supports millions of colors, offers great compression to keep file sizes small.

Cons: It's a "lossy" format, meaning some image data is permanently discarded during compression, which can create artifacts if over-compressed. Does not support transparency.

Best for: Photographs and complex images with many colors and gradients.

PNG (Portable Network Graphics)

Pros: "Lossless" compression, meaning no quality is lost. Supports transparency, making it perfect for logos, icons, and graphics with sharp lines.

Cons: File sizes are significantly larger than JPEGs, especially for complex photos.

Best for: Logos, icons, text-heavy images, and any graphic that needs a transparent background.

WEBP

Pros: A modern format developed by Google. It offers both lossy and lossless compression that is often better than JPEG and PNG, resulting in smaller file sizes at similar quality. It also supports transparency and animation.

Cons: While browser support is now excellent, very old browsers might not be able to display WEBP images.

Best for: Almost everything. It's a versatile, high-performance format for nearly any image on the web.

GIF (Graphics Interchange Format)

Pros: Supports animation, making it the classic choice for simple animated images. Lossless compression.

Cons: Limited to only 256 colors, which can make photos look poor. File sizes for animations can be very large compared to modern video formats.

Best for: Short, simple animations and logos with flat colors.
