How Image Size Affects SEO and User Experience

Speed is a Ranking Factor

Core Web Vitals are a set of metrics Google uses to measure user experience. One of the biggest factors? Largest Contentful Paint (LCP)—basically, how long it takes for the main content to load. Heavy images are the usual suspects for poor LCP scores.

The Mobile Data Drains

Over 60% of web traffic is mobile. If your user is on a faulty 4G connection and your home page has a 3MB banner image, they will bounce before it loads. A high bounce rate signals to Google that your content isn't valuable.

The Fix: Compression and Next-Gen Formats

1. Resize: Don't upload a 4000px wide photo if it will only be shown at 800px. Use our Image Resizer first.
2. Compress: Run your JPEGs through our Compressor to strip invisible metadata and optimize pixel data.
3. Convert: Switch to WebP. It offers superior compression compared to PNG or JPEG. Use our Converter tool.

Optimization doesn't mean pixelated, blurry photos. It means smart file handling.
