PrusaToOrca - PrusaSlicer to OrcaSlicer Profile Converter

Source code: https://github.com/La-Dosette/PrusaToOrca
Use it in your browser: https://la-dosette.github.io/PrusaToOrca/

PrusaToOrca converts a PrusaSlicer .ini config bundle into an .orca_printer bundle that OrcaSlicer can import. It is open source under AGPL-3.0.

▶ Browser or Windows

Browser
Drop in the .ini file and download the converted bundle. The file stays in the tab: nothing is installed or uploaded.

Windows
Download PrusaToOrca v1.1.0, unzip it anywhere, then run PrusaToOrca.exe. No installer is needed.

Both versions use the same conversion engine and produce identical output.

⚙ What it converts

The tool creates a new importable bundle; it does not edit the presets already stored in OrcaSlicer. Settings with a direct equivalent are copied. Approximate, unsupported, or ignored settings are shown in the conversion report so you can review them.

Windows desktop tools

• Single-file or folder-based batch conversion, with preview

• Strict and loose compatibility modes

• Preset prefixes and warnings for possible name collisions

• Custom mappings for unsupported PrusaSlicer settings

• Guided import, automatic backups, and conversion history

• Simple, technical, or advanced reports, exportable as CSV, HTML, PDF, or an anonymized bug report

The desktop interface is available in French, English, German, Spanish, Italian, Portuguese, Dutch, and Polish, with light and dark themes.

🧭 How I use it

1. Back up the OrcaSlicer profiles.

2. Export a PrusaSlicer config bundle as an .ini file.

3. Convert it with the browser version or the Windows app.

4. In OrcaSlicer, open File > Import > Import Config Bundle.

5. Select the generated .orca_printer file and review the imported presets.

⚠ Before you import

Slicer profiles are not perfectly interchangeable. A few PrusaSlicer settings have no direct OrcaSlicer equivalent, so check anything reported as approximate or ignored.

v1.1.0 changes the Windows packaging and release verification, not the conversion logic. Its output is byte-identical to v1.0.0. The antivirus detections reported for the old one-file executable were false positives caused by PyInstaller self-extraction. The technical details are in https://github.com/La-Dosette/PrusaToOrca/blob/main/SECURITY.md.

Windows builds are produced by GitHub Actions. Each release includes a SHA-256 checksum and signed build provenance, so the download can be checked against the published source.
