One gesture instead of an Export menu.

No app to open, no dialog to fill in. The converted copy lands right next to the original, which is never touched.

Step 1

Start dragging

Grab a file, or several, in Finder, on the desktop, or in any app that drags files.

Step 2

Hold ⇧

A wheel of every format that file can become opens under your pointer, with the size in the middle.

Step 3

Let go

Drop on a format. A small panel shows progress, then Finder selects the new file.

Hold ⌥ ⇧ for the tools.

The same gesture opens a wheel of tools for whatever you're dragging. Drop on one and its editor opens right where you let go.

  • Trim, split, crop and redact video on a real timeline, with frame-accurate or instant cuts.
  • Annotate, adjust, crop and redact photos, or put screenshots on a gradient background.
  • Normalize, trim and bleep audio, or turn it into a waveform video.
  • Compress anything to a preset or an exact file size.

182 conversions, offline.

Drop several files at once and the wheel offers the formats they share. Each format keeps its own defaults for quality, bitrate, size and metadata.

Your files stay on your Mac.

There is no network code in Clementine at all.

No uploads

Everything runs on-device with ImageIO, PDFKit, AVFoundation, Vision and local encoders.

No special access

It sees drags through the system drag pasteboard. No Accessibility or Screen Recording permission.

Originals untouched

Every result is a new file with a fresh name, right next to the one it came from.

Metadata, your call

Keep or drop it per format, or strip location and camera data in one drop.

Install in a minute.

macOS 14 Sonoma or later. Liquid Glass on macOS 26, with a Solid style if you prefer.

Download

  1. Get Clementine.zip from the latest release, unzip it and drag Clementine into Applications.
  2. It isn't notarized yet, so on first launch macOS says it can't verify it. Click Done, then System Settings → Privacy & Security → Open Anyway. Or run:
xattr -dr com.apple.quarantine /Applications/Clementine.app

Encoders for audio, video and WebP

Images, PDFs, text, archives and subtitles work out of the box. Audio, video and WebP use free encoders from Homebrew; Ghostscript makes PDF compression stronger.

brew install ffmpeg webp ghostscript

Or build it yourself: build from source.

Questions.

I hold Shift and nothing happens.

The wheel only opens during a real drag. Press on the file and move it a little until you see it under the pointer, then hold Shift. Dragging straight out of the Photos app doesn't hand over a file; drag the photo to the desktop first.

Shift already does something in my app while dragging.

Pick another modifier combination for either wheel in Settings → General → Drag Modifiers.

Why does macOS ask about my Desktop folder?

macOS asks every app once before it writes into Desktop, Documents or Downloads. Click Allow and Clementine can save beside your files there from then on.

Why don't I see audio or video formats?

Install the encoders with brew install ffmpeg webp. Clementine finds them automatically.

Is it really free?

Yes. MIT-licensed, no free-use limit, no account, no in-app purchase.
