High-quality photos can significantly slow down your website if they need to be properly optimized. Here’s how to optimize images for the web without compromising on quality:

  • PNG is better for images with text, transparent backgrounds, or images requiring high quality with lossless compression. PNG files are typically larger than JPEG.
