Saving and exporting

Duplicate, rename, or move the original

Niraqua DjVu opens .djvu files as read-only, but the standard macOS file commands are available in the File menu:

• File > Duplicate (⌘ ⇧ S) makes a copy of the open document.
• File > Rename renames the .djvu file in place.
• File > Move To moves the .djvu file to another folder.
• File > Share sends the original .djvu to Mail, Messages, AirDrop, or any other destination in the macOS share sheet.

These commands act on the file itself - the app never rewrites or alters the contents of your document.

The bundled sample document (Help > Open Sample Document) is the one exception: it cannot be duplicated, renamed, or moved, so those three commands do not appear for it. They are available for any .djvu file you open yourself.

Export to PDF

1. Open the DjVu document.
2. Choose File > Export as PDF or press ⌘ ⇧ E.
3. Choose a Quality preset (see below).
4. Optionally turn on Enable OCR to add a searchable text layer.
5. Choose where to save, then click Export.

Quality presets

Preset	Best for
Original	Lossless compression, largest files. Best for archival and maps.
High	Smart compression per page. A great balance of quality and size.
Compact	Smaller files for sharing and e-readers.

High is a good default for most documents.

Make the PDF searchable

Turn on Enable OCR in the export options to recognize the text and embed it in the PDF, so the exported file can be searched in any PDF reader. Pick the language that matches the document. If the document already has embedded text, OCR replaces it and the export may take several minutes.

If you only need search inside Niraqua DjVu, you can instead run text recognition without exporting.
