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. Under Pages, choose how much of the document to export (see below).
4. Choose a Quality preset (see below).
5. Optionally turn on Enable OCR to add a searchable text layer.
6. Choose where to save, then click Export.

Choose which pages to export

The Pages control at the top of the export options decides how much of the document ends up in the PDF:

Option	What it exports
All Pages	The whole document. This is the default.
Current Page	Only the page you were on when you opened the export options.
Page Range	Everything between From and To, including both.

Choosing Page Range reveals the From and To fields, filled in with the first and last page of the document. Page numbers start at 1 and both ends are included, so 2 to 4 exports three pages.

If the range does not make sense - a page beyond the end of the document, or a From larger than a To - the message Enter a valid page range. appears and Export stays dimmed until you correct it.

Exporting fewer pages is quicker, and it matters most with Enable OCR turned on: text recognition only runs on the pages you selected, so a short range from a long book finishes in a fraction of the time.

Quality presets

Preset	Best for
Original	Use as a reference when checking fine print, maps, and illustrations.
High	Start here for general reading; check small text and image detail after export.
Compact	Try for smaller files; check thin lines and small print after export.

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.
