# Open Tangerine
A local file converter and toolbox for **macOS**, with an early **Windows/Linux desktop edition**, by **Sintax Error Private Limited**.
Local processing, no account, no subscription. GPL-3.0-only. Safety limits apply.
**Mac status: 0.1.9 developer trial — ad-hoc signed, not Apple-notarized.** This is an independent project, not affiliated with Tangerine. It builds on Satsuma, with its MIT attribution preserved. It is not yet a complete replacement for Tangerine. See limitations.
## Windows and Linux desktop edition
The new **0.2.0 early desktop trial** is a separate implementation with a smaller feature set. Download status and installation · Desktop source and guide · Windows/Linux build checks.
| Platform | Interface | Availability / requirements |
|---|---|---|
| macOS | Native menu bar, global drag wheel and notch | v0.1.9; macOS 26+, Apple silicon |
| Windows | Batch file-drop window and progress panel | 0.2.0 early trial; Windows 10/11 x64; unsigned portable ZIP |

Desktop packages are published only after both CI jobs pass conversion tests and packaged startup/conversion checks. If the download page does not show a package yet, verification is still pending or the release could not be checked.
Windows/Linux include image conversion, resize/rotate, image-to-PDF, PDF merge/split/text extraction, simple SRT/VTT, SHA-256 and optional FFmpeg media conversion. **No global Shift wheel, physical notch, HEIC/SVG, Office conversion, OCR or full Mac editor parity in this edition.** Drop files into its window. Each failed file is reported independently. Originals and existing outputs are preserved. Workers have limits but are not an OS security sandbox; use trusted files. Detailed limits.
The illustrations below demonstrate the **Mac app**. The remaining Mac-specific sections describe its own capabilities.
## Download for Mac
