Compress Images Online Free - Reduce File Size Without Losing Quality

Large image files slow down websites, consume mobile data, and take longer to share on WhatsApp. Our image compressor reduces JPEG, PNG, and WebP image file sizes by 60-90% while maintaining visual quality. All compression happens in your browser - your images are never uploaded to any server, ensuring complete privacy.

For websites, Google PageSpeed Insights and Core Web Vitals penalise slow-loading pages. Images are typically the largest files on a webpage, and compressing them is the single most impactful optimisation you can make.

When to Use Each Image Format

  • JPEG: photos and complex images - lossy compression, smallest file size
  • PNG: logos, screenshots, graphics with transparency - lossless, larger files
  • WebP: best of both worlds - smaller than JPEG/PNG, supported by all modern browsers
  • SVG: logos and icons - vector format, infinitely scalable, tiny file size
  • AVIF: next-generation format - even smaller than WebP, limited support
