Permute is a native Mac media converter made by Charlie Monroe Software that transforms audio, video, and image files between formats through a drag-and-drop interface — no command-line knowledge required.
What is Permute?
Permute is a paid, native macOS application that converts media files — audio, video, and images — without routing you through a terminal or a tangled web of export dialogs. You drop files onto its window, pick a target format, and walk away. That deceptively simple pitch conceals a genuinely capable engine underneath: it handles obscure codecs, batch jobs, and even audio extraction from video with the same unfussy calm it applies to a single MP3.
Unlike the patchwork of FFmpeg front-ends that litter the Mac App Store, Permute feels like it was designed for people who have actual work to do — designers delivering audio assets, podcasters archiving interviews, musicians bouncing stems for a client who still insists on WMA. I've been using it as my daily conversion tool and the experience is remarkably friction-free.
What does Permute do best?
Permute's strongest suit is batch conversion with zero babysitting. Drop a folder of raw recordings onto the queue, choose FLAC or AAC or whatever the brief demands, and Permute churns through every file while you switch windows. It preserves metadata where the target format supports it, and it correctly handles multi-track video by letting you strip, keep, or remap audio streams — something simpler tools silently botch.
Audio extraction from video is the hidden killer feature. Need a clean WAV from a screen recording? Drag it in, point Permute at WAV, done in seconds. It also supports image conversion (HEIC to JPG being the obvious daily use case now that iPhones default to HEIC), which keeps the number of single-purpose utilities cluttering your Applications folder admirably low.
- Drag-and-drop batch conversion for audio, video, and images
- Audio-only extraction from any video format
- HEIC, WebP, and modern image format support
- Configurable output quality and sample rate per preset
- Retains ID3/metadata tags where applicable
- Apple Silicon native — conversions are fast on M-series Macs
How much does Permute cost?
Permute is a paid app, sold directly through Charlie Monroe Software's website and through the Mac App Store. There is no subscription — you pay once and own it. A free trial is available from the developer's site, which is the smarter way to evaluate it before committing, since the trial gives you a genuine sense of throughput on your own files rather than a cherry-picked demo video.
For professionals who convert media regularly, the price is negligible against the time saved in even a single busy week. Casual users who convert a file every few months might find the investment harder to justify, though the peace of mind of having a reliable tool on standby has its own value.
Who should use Permute?
Permute earns its keep for anyone who touches media files professionally: podcasters, video editors, musicians, designers, and developers who maintain asset pipelines. If you regularly receive files in formats your DAW or NLE won't touch natively, Permute eliminates the friction before it becomes a deadline problem.
It is equally at home for technically confident non-professionals — the photographer who needs to batch-convert a shoot from HEIC to full-quality JPEG, or the home archivist migrating a DVD rip collection to a modern format. What it is not is a heavy-duty professional transcoding suite with per-frame controls; for that kind of precision work, tools like HandBrake or FFMPEG directly give you more rope.
What are the best Permute alternatives?
The honest comparison set includes HandBrake (free, video-focused, far more encoding knobs), WWDC-era QuickTime (free, baked into macOS, extremely limited format coverage), and Permute's closest paid rival, Adapter (free but ad-supported and less actively maintained). For audio-only workflows, Fission from Rogue Amoeba is a stronger choice if you need non-destructive editing alongside conversion. FFmpeg in a terminal remains the power-user benchmark — everything Permute can do, FFmpeg can do faster with a crafted command, but Permute wins the entire category on time-to-result for non-terminal users.
If you want a no-compromise GUI that respects your time and runs natively on Apple Silicon, Permute is the most polished option in its bracket.
