Consul runs quietly in the Mac menu bar and watches configured folders, automatically converting files the moment their extension is renamed. Changing photo.heic to photo.jpg, for example, produces a converted JPEG instantly without opening any dedicated app. (Paid, one-time)
Users can monitor specific locations including Desktop, Downloads, or any custom folder added via drag-and-drop. Supported categories span images, video, audio, documents, spreadsheets, archives, e-books, and configuration files. Rather than trusting the file extension alone, Consul also inspects actual file contents and detects format mismatches, converting accordingly when a renamed extension does not match the underlying data.
Conversions happen entirely on-device using native macOS APIs with hardware acceleration. Most operations complete in under a second. A built-in history and backup system records every conversion, allowing any change to be undone if the result is unsatisfactory. No files are uploaded to any server, and the app includes no telemetry or tracking.
System requirements: macOS 12 or later (confirm on developer’s website). Uses native macOS conversion frameworks.
Pricing: (Paid, one-time, approximately $14–19 with one year of included updates; $9/year renewal optional thereafter)
Limitations: Not available on the Mac App Store; requires a direct download. Pricing follows an update-period model rather than a perpetual license — updates after the first year require an optional renewal fee. Some obscure format combinations may fall outside supported conversion paths.
Alternatives: Permute 3 ($6.99 one-time; dedicated media converter with queue-based interface), HandBrake (free, open-source; video-focused, no menu bar integration), FFmpeg (free, command-line; extensive format support but requires terminal use).
Suitable for users who regularly work with mixed file formats and prefer a passive, rename-triggered conversion workflow over manually opening a converter application.
