Squash
Squash is a batch image processing app for macOS that lets you quickly convert, resize, compress and rename photos in bulk. It supports format conversion including HEIC to JPEG, applies filters and effects, removes metadata, adds watermarks, and saves custom presets for repeated workflows. The app is built in Swift and SwiftUI and integrates with Apple Shortcuts for automation. It is used by photographers, content creators, and anyone who needs to process large folders of images faster than using Photoshop or Preview individually.
AI Recommendation
1 suggestionSquash is already a native Apple Silicon app—the vendor explicitly states it is a Universal Binary built to take advantage of Apple Silicon while remaining compatible with older Intel Macs. If you are running an older version of Squash, update to the latest release (version 3.2 or newer) through the Mac App Store or by downloading directly from realmacsoftware.com. The current build runs natively on M-series Macs and delivers full performance without Rosetta 2 emulation, so there is no migration needed for the macOS 28 deadline in September 2028.
