A file converter for macOS

Convert files without leaving Finder.

Start dragging a file, hold a key, and drop it on the format you want. Bremorph saves the result next to the original. Nothing is uploaded.

Pick a key, then click a slice. On your Mac you'd drop the file on it.

How it works

Three moves, and you never open the app.

  1. Start dragging a file

    Any file in Finder or on your desktop. Several files at once works too.

  2. Hold a key

    ⇧ shows formats, ⌘ shows tools, ⌃ shows actions like AirDrop or ZIP. A wheel opens under your pointer.

  3. Drop it on a slice

    The new file appears next to the original. Drop it in the middle if you change your mind.

Beyond converting

The small jobs you used to open a website for.

95 actions in all. These are the ones people reach for most.

Crop, mark up, hide

Crop to common ratios, draw arrows and text, and cover faces or account numbers before you share a screenshot.

Fit to an exact size

A form wants an image under 2 MB? Type the size and Bremorph keeps the best quality that fits. Works for video and PDFs too.

PDF pages

Reorder, rotate, delete and merge pages, or pull out only the ones you need.

Metadata and location

Edit titles, dates and keywords, or strip GPS location from photos before you post them. Photos aren't re-encoded.

From the terminal

Every action also runs from the command line, for example Bremorph --run vidWEBM clip.mp4.

English and Arabic

The whole app is translated, with a right-to-left layout in Arabic and correct Arabic plurals.

Formats

What goes in, what comes out.

.mkvDashed formats need ffmpeg or LibreOffice, both free. Bremorph finds them automatically.

Privacy

Your files stay on your Mac.

Bremorph has no network code. It converts with macOS's own frameworks, and with ffmpeg or LibreOffice if you install them, which run locally too. There's no account and no upload limit.

Get Bremorph

Free, for macOS 13 Ventura and later.

Download

Open Bremorph.dmg and drag Bremorph into Applications. It lives in the menu bar, so the wheel works whenever it's running. Runs on Apple silicon and Intel Macs.

Download for Mac

The app isn't notarized by Apple yet, so the first time you open it macOS says it can't check it. Go to System Settings → Privacy & Security and click Open Anyway.

Build it yourself

You need Apple's Command Line Tools. Xcode itself isn't required.

# xcode-select --install git clone https://github.com/Moha-Bremoo/Bremorph.git cd Bremorph ./build.command

For MKV, WebM, MP3 and more: brew install ffmpeg
