DropSlim

DropSlim is a lightweight, privacy-first desktop application for image optimization. It was created as a modern, future-proof alternative to existing tools that are no longer actively maintained. It bridges the gap between a dead-simple utility for everyday tasks and an efficient tool for developers outside of their main development environment.By leveraging Rust and Tauri, DropSlim runs 100 percent locally on your machine. Your images never leave your computer, there is no tracking, and no internet connection is required. It is perfect for quick tasks like shrinking images before sending them via email, or handing it over to clients so they can optimize their own web assets before uploading them to a CMS.Key features:The Desktop GUI (Windows and macOS): A minimalist interface built for everyone. Just drag and drop individual files or entire folders. Folders are processed recursively to save hours of manual work.The Desktop CLI (macOS and Linux): Perfect for running quick optimization scripts right from the terminal.DropSlim handles simultaneous batch processing without freezing and supports PNG, JPEG, WebP, AVIF, and native Mac HEIC. It is fully open-source under the MIT license and completely free, with no accounts, no subscriptions, and no paywalls.
