Image Compressor
Compress JPEG/WebP images with a quality slider. See before/after file sizes and download the result.
What is Image Compressor?
The Image Compressor reduces image file sizes using smart compression algorithms — applying lossy compression to JPEGs and lossless/near-lossless compression to PNGs — while maintaining visually indistinguishable quality. Images up to 90% smaller with no perceptible quality loss are common.
Images are the largest contributor to page weight on most websites, often accounting for 60–80% of total page size. Compressing images is the single highest-impact performance optimisation available, directly improving Core Web Vitals scores — particularly Largest Contentful Paint (LCP).
Why Use Image Compressor?
Unoptimised images are the most common cause of slow-loading websites. A 2MB photo that displays at 300×200 pixels is 10x larger than it needs to be. Image compression is the fastest, highest-impact performance improvement for most sites — this tool achieves it in seconds, in the browser.
