Does Cinder upload files to the internet?
No. Cinder reads the file where it is and writes the result in the same folder. No account. The file is not uploaded. Only the license identifier leaves the machine.
Answers
The facts, plainly.
What Cinder does, what it costs, and what it does not do yet.
How much does Cinder cost?
The first 20 successful files are free, then €29.99 once, with no subscription.
Which systems does Cinder run on?
Windows 10 or 11, without administrator rights. macOS 12 or newer: on the first launch, right-click, then Open. Allow Accessibility and Input Monitoring.
Do I need to install ffmpeg?
On Windows, no: ffmpeg is included with Cinder. On macOS, install it with Homebrew. Cinder then looks in /opt/homebrew/bin/ffmpeg, then /usr/local/bin/ffmpeg.
Which formats are not here yet?
Not yet HEIC, AVIF, or PAGES. Crop, redact, and annotate are not in this version.
Can Cinder convert several files at once?
No. The wheel acts on the file under the cursor. It is not a batch conversion.
