Images are usually the heaviest assets on a website. Compressing them properly can cut load times in half without anyone noticing a quality drop.
JPG (or JPEG)
Best for photographs and complex images. Uses lossy compression, which discards data to shrink file size. Quality settings between 70 and 85 are usually invisible to the eye but reduce size by 50 to 80 percent.
PNG
Best for graphics, logos, icons and anything with transparency. Uses lossless compression, so the image keeps every pixel exactly. PNG files are larger than JPG but preserve sharp edges and transparency.
WebP
A modern format from Google. WebP files are typically 25 to 35 percent smaller than equivalent JPG or PNG, with no visible quality loss. All modern browsers support it.
Practical tips
For photos, use JPG with quality 80 or WebP. For logos and graphics, use PNG or WebP. Always compress before uploading to your site or sending in email.
