What is Image Compression?

Image compression reduces the file size of JPG, PNG, and WebP images while preserving visual quality. Smaller images load faster, reduce bandwidth costs, and improve your Core Web Vitals scores.

How to Compress an Image Online

Upload your JPG, PNG or WebP file, adjust the quality slider (75% is the recommended sweet spot), then click Compress Image and download the result. Our server-side Pillow processing achieves reductions of 50–80% with virtually no perceptible quality loss.

Why Use This Free Image Compressor?

Unlike browser-based tools that use the basic Canvas API, we process images server-side with progressive JPEG encoding and chroma optimization. No registration, no watermarks, no file size limits beyond 100 MB.
