Compress and optimize images for the web.

Web image optimization is a ranking factor.

Google's Core Web Vitals — specifically Largest Contentful Paint (LCP) — directly measures how quickly your page loads its main content. Images are almost always the largest element on the page, and uncompressed images are the most common reason for failing LCP. A single unoptimized hero photo from a modern smartphone (4-6 MB) can push LCP past 5 seconds on a mobile connection — well beyond Google's 2.5-second threshold.

The fix is straightforward: resize images to their display dimensions, compress them with quality 75-85, and serve them in a modern format like WebP or AVIF. A 5 MB hero image becomes 200-500 KB with no visible quality difference. Page speed improves by seconds. Google rewards the improvement with better rankings. Our compressor handles all three steps — resize, compress, and format conversion — in one pass, entirely in your browser.

The web optimization workflow

Start by auditing your site with PageSpeed Insights or Lighthouse to identify pages with poor LCP scores. Download the unoptimized images, process them through our compressor with these recommended settings, and re-upload:

• Format: Convert to WebP (primary) with JPEG fallback
• Quality: 80 for photos, 75 for graphics, 90 for product detail shots
• Resize: Cap width to the maximum display size in your layout
• Metadata: Strip EXIF data — GPS coordinates and camera settings add kilobytes with no benefit to visitors

For e-commerce sites with hundreds of product images, use our bulk compressor to process entire catalogues in parallel. For format-specific compression, see JPEG Compressor, WebP Compressor, and AVIF Compressor. Need to resize? Use the Image Resizer.

Real-world performance gains

A typical website audit reveals the same pattern: unoptimized images account for 60-80% of total page bytes. Compressing images at quality 80 and converting to WebP reduces image weight by 70-85%. For a page with 2 MB of images, that means serving 300-600 KB instead. On a 4G mobile connection, this translates to 1.5-3 seconds faster loading — the difference between a passing and failing LCP score. For image-heavy pages like e-commerce category pages or photography portfolios, the gains are even larger.
