Smart Image Compression

Slow websites lose visitors. Large images are the #1 cause of slow loading speeds. Our Free Image Compressor solves this problem by using smart lossy compression techniques to reduce the number of colors in the image data.

The effect is nearly invisible to the eye, but very visible in file size! You can often reduce a 5MB photo to just 500KB without noticing any difference in quality.

Boost SEO

Google loves fast sites. Smaller images mean faster load times and better rankings.

Secure

Compression happens in your browser. We never see your photos.

Customizable

You control the balance between quality and file size with our slider.

How to Compress an Image

  1. Upload: Select your high-resolution image.
  2. Adjust Quality: Use the slider to find the perfect balance. Lower quality = smaller file size.
  3. Download: Save the optimized image instantly.

Frequently Asked Questions

JPEG is best for photos. WebP is best for websites (smallest size). Use PNG only if you need transparency, but it won't compress as much.

Our tool defaults to 80% quality, which is the "sweet spot." It significantly reduces file size while remaining sharp to the human eye.
