Best for: Photographs and complex images with many colors.
JPEG is one of the most widely used image formats on the web. It uses lossy compression, which reduces file size by discarding some image data. While this can result in a slight loss of quality, it’s often unnoticeable for most web applications.
Pros:
Cons:
When to Use: Use JPEG for blog post images, product photos, and any content where file size is a priority over perfect image quality.
Best for: Graphics, logos, and images with transparency.
PNG is a lossless format, meaning it retains all image data during compression. It’s perfect for images that require high quality and transparency, such as logos or icons.
Pros:
Cons:
When to Use: Use PNG for logos, icons, and images that require transparency or high detail.
Best for: Simple animations and low-color images.
GIFs are best known for their ability to support animations. However, they’re limited to 256 colors, making them unsuitable for high-quality images.
Pros:
Cons:
When to Use: Use GIFs for simple animations, memes, or low-color graphics.
Best for: Logos, icons, and scalable graphics.
SVG is a vector-based format, meaning it uses mathematical equations to create images. This allows SVG files to be scaled infinitely without losing quality.
Pros:
Cons:
When to Use: Use SVG for logos, icons, and graphics that need to be resized frequently.
Best for: Modern websites looking for a balance between quality and performance.
WebP is a relatively new format developed by Google. It offers both lossy and lossless compression, providing high-quality images with smaller file sizes.
Pros:
Cons:
When to Use: Use WebP for modern websites where performance and image quality are priorities.

File Size vs. Quality: Do you prioritize fast loading times or high-quality visuals?
Platform Compatibility: Will the image be used on a website, social media, or print?
SEO Considerations: Optimize images for faster loading times and better rankings.
