image compressor

Reduce image file sizes with adjustable quality control while maintaining visual clarity for web and sharing.

Image Compressor lets you shrink the file size of your photos and graphics by re-encoding them at a quality level you control. Using an intuitive slider from 1% to 100%, you can find the perfect balance between file size and visual quality — often achieving 50-80% size reductions with barely noticeable differences to the human eye.

Web developers and site owners benefit significantly from compressed images. Smaller files mean faster page loads, better Core Web Vitals scores, and reduced bandwidth costs. Search engines favor fast-loading pages, so compressing your images directly contributes to improved SEO rankings and user experience.

The tool accepts all common image formats including JPG, PNG, WebP, and GIF. It re-encodes the image as an optimized JPEG, which is ideal for photographs and complex images. The real-time preview shows both the original and compressed file sizes along with the exact percentage reduction achieved.

All compression happens locally in your browser using the Canvas API — no images are uploaded to external servers. Your files remain completely private. Simply upload an image, adjust the quality slider to your preference, and download the optimized result instantly.
