Image Compressor

ImageOffline-ready

Image Compressor reduces JPEG and WebP file sizes by re-encoding at a lower quality level — a slider lets you balance quality vs file size. Shows original and compressed sizes and the percentage reduction so you can find the right trade-off. Everything runs in your browser — no file is uploaded to a server. Download the compressed image with one click.

Image compressor — reduce file size

Reduces image file size by adjusting JPEG quality or PNG compression level. Smaller images mean faster page loads and lower storage costs. All compression runs client-side in the browser — no file is uploaded. Typical JPEG quality of 80% retains near-lossless visual quality at 50–70% smaller file size.
