Convert & Compress

Convert & Compress is a native macOS image utility for converting, resizing, cropping, and compressing images locally.

The app is built with SwiftUI and a Core Image based processing pipeline. It supports batch workflows, broad image format coverage, metadata control, presets, and private offline processing.

Features

• Batch convert images with drag-and-drop, paste, and folder workflows.
• Convert across 50+ input formats and 20+ output formats, including JPEG, PNG, HEIC, WebP, AVIF, TIFF, SVG, RAW, ICNS, ICO, and PDF.
• Resize or crop images, including format-aware size constraints for icon formats.
• Adjust compression quality where supported by the target format.
• Preserve or remove privacy-sensitive metadata.
• Save reusable presets that sync through iCloud.
• Process images locally without uploading them to a server.

Requirements

• macOS 14.6 or later
• Xcode 26 or later
• Swift 6.2 toolchain
