Why Compress Images for the Web?
Faster Page Loads
Uncompressed images can add seconds to your page load time. Compressed images help your pages load in under 2 seconds, reducing bounce rates by up to 50%.
Better Core Web Vitals
Google uses Core Web Vitals as a ranking factor. Compressing images directly improves your LCP (Largest Contentful Paint) score and overall search ranking.
Lower Bandwidth Costs
Smaller image files mean less data transferred, which reduces your CDN and hosting bandwidth costs significantly on high-traffic sites.
Mobile Performance
Mobile users on slower networks benefit the most from compressed images. Keep your mobile visitors engaged with fast-loading pages.
100% Private
Your images are processed entirely in your browser. Nothing is uploaded to any server. Perfect for sensitive website assets.
WebP Format
Convert to WebP for the best web compression. WebP files are 25-35% smaller than JPEG at equivalent quality, with broad browser support.
Frequently Asked Questions
What image format is best for web pages?
WebP is generally the best format for web images because it provides superior compression compared to JPEG and PNG while maintaining good visual quality. Most modern browsers support WebP. For photos, JPEG is a solid fallback. For images with transparency, use WebP with alpha or PNG.
How does image compression affect Core Web Vitals?
Large uncompressed images hurt your Largest Contentful Paint (LCP) score, which is a key Core Web Vitals metric. Compressing images reduces file size, allowing the browser to download and render them faster. Aim for images under 100KB where possible to keep LCP under 2.5 seconds.
What quality setting should I use for web images?
For web images, a quality setting of 70-80% offers the best balance between file size and visual quality. At 75% quality, most images lose 50-70% of their file size with virtually no visible difference. For hero images or product shots, use 80%. For thumbnails, 65-70% is usually sufficient.
