Image Compressor

Compress JPG images to reduce file size while balancing quality.

An image compressor reduces an image's file size by re-encoding it at a lower quality setting, helping pages load faster without a visible loss in quality.

Choose an image from your device. It is processed locally and never uploaded.
70
Lower quality = smaller file, more artifacts.

How to Use the Image Compressor

  1. Upload an image. Choose a JPG or PNG image from your device.
  2. Adjust quality. Drag the quality slider to balance size and clarity.
  3. Download the result. Compare before/after sizes and download the compressed image.

What Is Image Compressor?

Compressing images reduces their file size, which speeds up page loads and improves Core Web Vitals without requiring a different format.

What is image compression?

It reduces file size by removing or approximating visual detail. This tool re-encodes to JPEG at a chosen quality, which is a lossy method that trades quality for size.

Why compress images?

Images are often the largest assets on a page. Smaller files load faster, use less bandwidth and improve user experience and SEO metrics like LCP.

Choosing a quality level

A quality of 70–80% usually looks close to the original while cutting size significantly. Very low quality introduces visible artifacts like blocking.
