ConvertIt provides on-demand conversions across 20 categories directly from the menu bar, activated via a customizable hotkey. It combines a unit and currency converter with batch media file conversion and renaming in a single free app.
The converter covers temperature, length, weight, area, volume, speed, time zones, number bases (binary, hexadecimal, octal), data storage, and currency. Quick mode interprets plain-English conversion phrases and delivers results in real time as users type, with the result copyable by pressing return. A guided dropdown mode provides the same conversions for users who prefer a structured interface.
Currency conversion uses live exchange rates cached for 24 hours, so offline use remains available using the most recent rates. This makes it suitable for situations without consistent internet access.
The batch media conversion tool handles image, audio, and video files without requiring separate specialized apps. Batch renaming accepts pattern tokens for systematic file naming across multiple files simultaneously.
System requirements: macOS 14 Sonoma or later. Compatible with Apple Silicon and Intel Macs. Available on the Mac App Store and via direct download.
Pricing: Free. No account, subscription, or ads.
Limitations: The app requires macOS 14, excluding users on macOS 13 or earlier. The batch conversion feature handles common formats but may not cover specialized or professional formats. Advanced currency features requiring real-time rates depend on internet connectivity for updates.
Alternatives: Lungo and other system tools include basic unit conversion. Klack, Raycast, or Alfred provide conversion through extensions. Permute handles dedicated video conversion with more format options.
Suitable for users who frequently need quick unit or currency conversions, or those wanting a lightweight free tool that combines conversions with basic batch file processing.
