Free Online Image Compressor

An image compressor reduces the file size of images while preserving acceptable visual quality. Large images are one of the biggest contributors to slow page load times: compressing them is one of the highest-impact optimizations you can make for web performance, Core Web Vitals scores, and SEO rankings.

This online image compressor processes everything in your browser using client-side JavaScript. Your files are never uploaded to any server, ensuring complete privacy. It supports JPEG, PNG, WebP, and AVIF with batch processing and ZIP download.

JPEG, PNG, WebP, or AVIF: which format should you use?

  • JPEG: Best for photographs and complex images with gradients. Typical web quality setting: 75 to 85.
  • PNG: Best for images with transparency, sharp edges, or text overlays. Lossless compression only.
  • WebP: 25 to 35% smaller than JPEG at equivalent quality. Supported in all modern browsers. The recommended default for web images.
  • AVIF: 50% smaller than JPEG in many cases. Best compression available, with support in Chrome, Firefox, and Safari 16+.

How to compress images online

  1. Drag and drop your images or click to upload (JPEG, PNG, WebP, AVIF accepted).
  2. Choose compression mode: Smart (auto), custom quality, or target file size.
  3. Optionally convert to WebP or AVIF for maximum size reduction.
  4. Review before/after file sizes and compression ratios in real time.
  5. Download individual files or all compressed images as a ZIP archive.

Recommended file size targets for web

  • Hero images: under 200 KB (ideally under 100 KB for mobile-first).
  • Product images: under 100 KB per image for e-commerce pages.
  • Thumbnails: under 20 KB.
  • Background images: under 150 KB, use WebP or AVIF whenever possible.

Image compression and Core Web Vitals

Google's Largest Contentful Paint (LCP) metric is heavily affected by image load time. Compressing your hero and above-the-fold images is one of the fastest ways to improve LCP scores and pass Core Web Vitals thresholds. Use the target file size mode to compress images to a specific budget without manual trial and error.
