Convert All

Built for the moments
when seconds matter.

You dropped a 40 MB screen recording into Slack and got "file too large." You need to email a PDF that's just over the limit. You're trying to open an MKV in QuickTime. Convertible handles all of these in seconds — locally, without uploading.

🎯

Fit-to-target presets

One click to fit files under Email (25 MB), Discord (10 MB), iMessage (100 MB), or WhatsApp (16 MB). No guessing at bitrates or dimensions.

Instant stream copy

MKV to MOV, MP4 to MOV — when codecs match, Convertible just rewraps the container. A 10 GB file converts in seconds with zero quality loss.

🔒

Everything stays local

Your files never leave your Mac. No cloud uploads, no telemetry, no tracking. The app works completely offline.

⚙️

Hardware accelerated

Uses Apple's VideoToolbox and sips for native performance. Conversions fly on Apple Silicon — no beachball, no CPU meltdown.

🎨

Compress without converting

Have a 35 MB PDF for email? Shrink it to 10 MB while keeping it a PDF. Same for video, audio, and images.

🧩

Formats Apple forgot

MKV, WebM, FLAC, OGG — the formats QuickTime refuses to touch. Convertible handles them all without bloat.

Right-click.
Done.

The fastest conversion is the one you never opened an app for. Convertible adds "Convert to" directly to your Finder right-click menu. Pick any file, pick a format, and it converts in place — no window, no drag-and-drop, no clicks wasted.

  • Works on any file, anywhere in Finder
  • Select multiple files for batch conversion
  • Converts in the background without blocking Finder
  • Notification when done, output saved next to original

Answers to the
questions you'll ask.

How is this different from macOS Quick Actions?
macOS has a built-in "Convert Image" Quick Action that handles PNG, JPG, and HEIC. Convertible does much more: video formats (MKV, WebM, MP4, MOV), audio (MP3, FLAC, etc.), PDF compression, fit-to-target size presets, and batch processing. Plus a Finder extension that works everywhere.
Is it really a one-time purchase?
Yes. $9 once, yours forever. All future updates and new formats are included. No subscription, no "Pro" tier upgrade, no "pay to unlock" when the next major version ships.
What's the difference between the free tier and Pro?
The free tier includes unlimited image conversions, all resize presets, and the Finder extension for images — forever, no limits. Pro unlocks unlimited video, audio, and PDF conversions. Free users get 3 media conversions and 5 PDF conversions per month as a taste.
Can I really convert MKV files?
Yes — this is one of the main reasons people buy Convertible. macOS can't open MKV natively (QuickTime, iMovie, Final Cut don't support it). Convertible converts MKV to MOV or MP4 instantly when the video inside uses common codecs like H.264 or H.265, with zero quality loss.
Does it work offline?
Completely. The only network call Convertible ever makes is when you purchase through Apple's App Store. After that, disconnect your Mac from the internet and everything still works.
What macOS versions are supported?
Convertible requires macOS 14 (Sonoma) or later. It runs natively on both Apple Silicon and Intel Macs.
Can I request a new format?
Absolutely. Email [email protected] with your use case. Future formats are included in your purchase — if I add it, you get it.
Is my data sold or tracked?
Never. Convertible has no analytics SDKs, no telemetry, and no third-party tracking. Crash reports only come through Apple's MetricKit system, and only if you've explicitly opted in at the OS level. Your files stay on your Mac.
