✨ New Features

  • JPEG Compression Engine Enhanced — Fine-tuned compression parameters with a brand-new pipeline for better results and faster processing.
  • PNG Compression Engine Enhanced — Brand-new in-house engine delivers faster compression at comparable quality, with added APNG animated image support (Pro).
  • SVG Compression — Optimize SVG files with 6 compression levels, from conservative to maximum; comparison view renders SVGs as live vectors (Pro).
  • Enhanced PDF Compression — New Ghostscript engine delivers dramatically better PDF compression with font and stream optimization; encrypted PDFs are detected with a friendly prompt (Pro).
  • Smart Skip for Compressed Files — Automatically recognizes previously compressed files to avoid redundant processing; re-compresses when settings change or files are modified.
  • Quick Preset Switching on Drop — Hold ⌥ (Option) while dragging files to the main window or notch area to quickly choose a different compression preset.
  • Debug Mode — Tap the app icon 5 times in the License view to activate; easily export runtime logs for troubleshooting.

🐛 Bug Fixes

  • Fixed JPEG compression causing thin lines to split and produce ringing artifacts.
  • Fixed NotchDrop and notification windows not appearing in full-screen apps.
  • Fixed missing close animation when NotchDrop disappears.
  • Fixed trackpad two-finger gestures and other non-drag actions falsely triggering NotchDrop.
  • Fixed Finder window title bar drag falsely triggering NotchDrop.
  • Fixed files not being compressed after dropping onto the Notch area.
  • Fixed NotchDrop falsely appearing after display changes or lid open/close.
  • Fixed voice input and other transient clipboard content triggering repeated compression.
  • Fixed clipboard monitor writing back results for non-image content.
  • Fixed crash when clicking the license Manage button.

🚀 Other Improvements

  • Better Color Fidelity — Wide color gamut (Display P3) images are no longer downgraded to sRGB, preserving accurate colors.
  • HDR-Safe Processing — HDR photos retain their high dynamic range data during compression.
  • ICC Profile Preservation — WebP, AVIF, TIFF and other formats now preserve original color profiles for consistent color reproduction.
  • Improved Dependency Installation — External tool installation now uses an in-app guided window with download progress and automatic retry.
  • File monitoring deduplication is more reliable, eliminating potential runaway list growth.
