What it is
DropMorph is a free desktop file converter. Instead of opening a window, picking a format and clicking convert, you hold Ctrl, drag your files, and drop them on a format in a donut menu that opens right at your cursor.
It covers 254 formats, from images and PDF to Office documents, e-books, CAD and 3D files.
Why offline matters
Online converters need you to upload the file. DropMorph runs on your own machine, so nothing is uploaded. That makes it suitable for documents you would rather not send to a third-party website.
How it is built
The app is written in C# on .NET with the Avalonia UI toolkit, which is how a single codebase ships for Windows, macOS and Linux. The current release is v1.12.0.
Try it
You can download it from the project site, and the source is public on GitHub.
