Squoosh

Overview

Squoosh is a browser-based image optimizer that compresses images directly on your device. It reduces file size while maintaining high visual quality so web pages load faster.

The tool works entirely in the browser without uploading images to any server. This keeps your files private and secure. Squoosh is open source and available on GitHub.

Key Benefits

• Images never leave your device because all processing happens locally in the browser.
• File sizes shrink significantly — sample images as small as 13 KB are shown as achievable results.
• Side-by-side comparison lets you inspect visual differences before saving.
• Simple workflow: open an image, inspect differences, and save instantly.
• Advanced settings are available for users who want even smaller file sizes.

How It Works

You drop or paste an image into the browser window. Squoosh displays the original and compressed versions side by side so you can compare quality. You adjust codec and compression settings, then save the optimized image directly to your device.

Use Cases

• Front-end web developers optimizing images for faster page load times.
• Designers preparing compressed assets for production without sacrificing quality.
• Privacy-conscious users who need image compression without uploading files to a remote server.
• Hobbyist bloggers reducing image file sizes to improve their site performance.

Why Choose This Product

Squoosh is best for anyone who needs quick, private image compression without installing software or trusting a third-party server. It is limited to single-file processing in a modern browser and requires JavaScript to be enabled.
