Squash Overview
Squash is an image-compression and conversion application for macOS that reduces image file sizes and converts between formats with a simple drag-and-drop workflow. It compresses images (such as JPEG, PNG, and WebP) to make them smaller for the web while aiming to preserve visual quality, supports modern formats like WebP and HEIC, can resize and convert in batches, and integrates cleanly into a designer's workflow. Its focus on a fast, straightforward experience makes it popular with Mac designers and developers preparing assets for websites and apps. It is downloaded and installed from the developer's official site. It can strip metadata for privacy, apply consistent settings across a batch, and place compressed copies right where you need them.
