Image Compressor

Image compression is one of the single highest-impact optimizations you can make for your website's performance. According to Google's web performance data, images account for 50–70% of the total bytes on most web pages. Unoptimized images are the #1 cause of slow page load times, poor Core Web Vitals scores, and high bounce rates.

Our image compressor uses a smart compression algorithm that analyzes each image and applies the optimal settings to achieve the smallest file size while maintaining visual quality that appears indistinguishable from the original.

How compression works For JPG images, we use a perceptual compression model that removes data that human eyes are least sensitive to — similar to how MP3 audio compression removes frequencies humans can't hear. For PNG images, we apply lossless optimization that reorders file data more efficiently without removing any pixel information. For WebP, we use Google's advanced compression algorithm that achieves 25–35% better compression than JPG at the same quality level.

Impact on Core Web Vitals Google's LCP (Largest Contentful Paint) metric — a key ranking factor — is directly impacted by image loading speed. Compressing your hero images can dramatically improve your LCP score from "Needs Improvement" (2.5–4s) to "Good" (under 2.5s), positively affecting your search rankings.

Best practices for web images - Hero images: Target 100–200KB maximum - Blog post images: Target 50–150KB - Thumbnails: Target 20–50KB - Product images: Target 100–300KB

Supported formats Our compressor supports JPG/JPEG, PNG, WebP, and GIF. For best results with photographs, use JPG. For graphics with text or transparent areas, use PNG or WebP.
