Supported File Types
The File extension lets you keep source material inside a project. Supported uploads stay in their original format and can be downloaded again later.
Upload and preview
| Kind | File types | Preview in Lunaris |
|---|---|---|
| Documents | .pdf, .docx | Yes |
| Presentations | .pptx | Yes |
| Spreadsheets | .xlsx | Yes |
| Images | .jpg, .jpeg, .png, .webp, .gif | Yes |
| Plain text | .txt | Yes |
| Markdown | .md | Yes |
| Structured text | .csv, .json, .xml | Yes |
These formats can be selected from Add file → File when the File extension is enabled. The preview is for reading the uploaded file; it does not convert the file into an editable Lunaris document.
An uploaded file can remain useful even if its preview cannot load. Open the file’s More menu and choose Download to save the original file to your device.
Document export
Documents created with the Rich Text extension can be exported as:
- PDF for a fixed-layout copy; or
- Markdown (
.md) for portable, editable text.
The Compiler extension can also combine supported project items into one PDF. Uploaded files are not automatically merged into a compilation.
Project import
Import from Obsidian accepts a folder or vault and converts .md and
.markdown notes into editable documents. It preserves supported folders and
keeps supported source files in an Original Files folder. Hidden and
unsupported files are skipped, and the import summary shows the result before
the project is created.
See Add and Preview Files, Export and Copy Documents, or Import from Obsidian for instructions.
