Here’s a summary of the seven main image extensions you can use, depending on your needs:

• JPEG: Ideal for photos and complex images.
• PNG: Best for graphics and logos with transparency.
• GIF: Primarily used for animations.
• TIFF: Used in high-quality printing and preserving details.
• SVG: Scalable vector format, great for responsive icons and graphics.
• BMP: An older format, still useful in environments that require uncompressed images.
• WEBP: A modern format that offers a good balance between quality and compression, recommended by Google.

Each format has its advantages, and the right choice depends on factors like image purpose, desired quality, and file size limitations.
