Image Compressor — Reduce File Size Online

Compress Images Without Losing Quality

Large images are one of the biggest causes of slow websites. A single unoptimized photo can be 3–8 MB. Compressed at 80% quality to WebP, the same image is often 200–400 KB — an 85%+ size reduction with no perceptible visual difference.

How Much Can You Compress?

• JPG at 75%: Typically 40–60% smaller than original with barely noticeable quality loss
• WebP at 80%: Typically 50–70% smaller than original JPG at equivalent perceived quality
• PNG: Lossless — file size reduction is less dramatic (10–30%) since the original is already lossless

Why Image Size Matters for SEO

Google's Core Web Vitals include Largest Contentful Paint (LCP) — how fast the main image on a page loads. An LCP above 2.5 seconds is "needs improvement." Unoptimized images are the #1 cause of poor LCP scores. Compressing images directly improves your Google ranking potential.
