Image Compression Best Practices

Large images slow down pages and hurt Core Web Vitals. Learn how to compress responsibly for web, social, and email.

Choose the right format

JPEG suits photographs. PNG preserves sharp edges and transparency for logos and UI assets. WebP often gives the smallest size when your CMS supports it.

Quality vs file size

Compression works by discarding data humans barely notice. Start at 80–85% quality for photos; go lower only if banding appears in skies or skin tones. Always compare before/after at 100% zoom.

Using Toolsminer Compress Image

Upload your image to our Compress Image tool, review the preview, and download the optimized version. Batch workflows can run file-by-file within free tier limits or upgrade to Premium for heavy daily use.

SEO impact

Google uses Largest Contentful Paint (LCP) as a ranking signal. Compressing hero images and serving responsive sizes (`srcset`) often improves LCP more than lazy-loading alone.
