What is Convertessa?

Convertessa is a native macOS app that converts files between formats - images (HEIC, WebP, PNG, JPG, TIFF, GIF), audio (MP3, AAC, FLAC, OGG, WAV), video (MOV, MP4, MKV, AVI, WebM), documents (PDF compression), fonts (TTF, OTF, WOFF, WOFF2) and ebooks - covering 1,100+ conversion combinations across seven categories.

Every conversion runs locally on your Mac. Your files never leave your device, and no internet connection is required. Unlike browser-based converters that upload your files to unknown servers, Convertessa is a true Mac-native app built for macOS 14+ with full Apple Silicon and Intel support.

Key features:

  • Drag-and-drop batch conversion with quality controls (compression level, resolution, bitrate)
  • Command-line interface for scripting and automation
  • Right-click Finder integration (Quick Action)
  • Collision-safe naming and conversion history
  • Compact mode for minimal workspace footprint
  • Universal binary: Apple Silicon + Intel native
  • Zero telemetry, zero file uploads

One-time purchase of $19. No subscription. No renewals. Lifetime updates included. 14-day money-back guarantee.
