A Guide to Perfect Website Images

For a smooth-running website that doesn't sacrifice quality, the key is to focus on file size and image dimensions. Aim to keep your image file sizes under 500 KB, though under 200 KB is even better for optimal performance.

Image Dimensions for Common Uses

The ideal dimensions depend on how an image will be used. It's crucial to resize your images to these dimensions before uploading them to your website. Uploading a large image and letting the browser resize it slows down your site.

• Full-Width Images (Heros or Banners): 1920 pixels wide is a good standard. The height will depend on your design, but a 16:9 ratio is common.
• Content Images (within a blog post): Aim for a width between 1200 and 1600 pixels.
• Thumbnails: These can be much smaller, typically around 150x150 pixels to 300x300 pixels.

Choosing the Right File Format

The file format plays a significant role in both quality and file size:

• JPEG: The best choice for photographs and images with many colors. JPEGs use "lossy" compression to find a good balance between quality and size.
• PNG: Use for images that require a transparent background, such as logos or icons. PNGs use "lossless" compression, so file sizes are generally larger.
• WebP: A modern format that provides excellent compression while maintaining high quality. It's a great option for both photographic and transparent images.
• SVG: The ideal choice for logos, icons, and simple illustrations. As a vector format, SVGs look crisp at any size and their file sizes are tiny.

Compression is Key

After resizing and choosing the right format, the final step is to compress your images:

• Lossy Compression: Significantly reduces file size by permanently removing some imperceptible image data. Ideal for most web images.
• Lossless Compression: Reduces file size without any loss of quality by removing non-essential metadata.
