Image Optimizer

Optimized images load faster, improve user experience, reduce bandwidth usage, and boost SEO rankings. Google considers page speed as a ranking factor, and large unoptimized images can significantly slow down your website, leading to higher bounce rates and lower search engine rankings.

JPEG is best for photographs with many colors but doesn't support transparency. PNG supports transparency and is ideal for graphics, logos, and images with few colors. WebP is a modern format that provides better compression than both JPEG and PNG while supporting transparency, but isn't supported by all browsers.

For web use, you can typically compress JPEG images to 70-80% quality without noticeable quality loss. PNG images can often be reduced by 20-50% through optimization techniques. The key is finding the right balance between file size and visual quality for your specific use case.

Use dimensions that match how the image will be displayed. For hero images, 1920x1080px is common. For blog post images, 800-1200px width is typical. For thumbnails, 300-400px width is sufficient. Always consider responsive design and provide appropriate sizes for different screen sizes.
