Squoosh - Optimize and preview images in one place

Description

When you have a batch of high-resolution images that need to be web-ready, you usually face a trade-off between file size and visual clarity. This tool lets you experiment with various compression settings while watching the results update in real time. You can drag and drop your files, adjust quality sliders, and immediately see how different codecs change the look of your photo. It saves you from guessing how much detail you might lose before you commit to an export. Because this runs directly on your device, your images never leave your local environment to be processed on a remote server. You have full control over the output, from resizing dimensions to choosing the exact format that works for your specific project. It handles everything from quick tweaks to heavy optimization tasks without slowing down your machine or requiring a constant connection once the initial resources are cached 🖼️. • Side-by-side comparison slider for quality checking • Support for modern formats like AVIF and WebP • Local processing for privacy and speed • Resize, rotate, and palette adjustments • Instant visual feedback on file size changes This is a web app that lives on your device just like a native tool. You simply visit the site in your browser, tap the install button to add it to your home screen, and it opens in its own window without any address bars or tabs. It updates itself automatically in the background, works offline, and keeps your dock clear of heavy software installers ⚙️. It is the same core experience as the version you might find in a traditional software marketplace, only faster to access and without the need for a store account.
