EggplantTinyPNG

Native macOS 15+ image compressor — drag photos in, shrink them on your Mac, keep the originals.

简体中文

Download from Releases (DMG, ad-hoc signed — not notarized).

What it does

• Drop or open PNG, JPEG, or WebP
• Compress locally — nothing is uploaded
• Auto-save next to the original as name-tiny.ext
• See progress for the whole batch; jump to a file in Finder when it’s done, or Overwrite Original
• Themes and language (System / English / 简体中文) in Settings

Closing the window keeps the app in the Dock. Quit with ⌘Q.

Get started

1. Install from the DMG (drag to Applications).
2. If macOS blocks it: xattr -cr /Applications/EggplantTinyPNG.app
3. For best PNG results, install helpers once: brew install pngquant oxipng
4. Drop images in and you’re done.

Build from source

See docs/commands.md. Requires macOS 15+ and Xcode 16+.
