Why convert DJVU to PDF?
PDF opens on every phone, e-reader, tablet, and browser without extra software, while a DjVu reader is required to view .djvu files and most people do not have one installed. .pdf is the practical choice for sharing scanned books, articles, or documents with a general audience who should not need to install anything.

Open .PDF details →Quality & what to watch
- File size increases noticeably: DjVu uses specialized layered compression (JB2 for text, IW44 wavelet for backgrounds) while the PDF wraps the same images in standard JPEG or TIFF compression.
- The OCR text layer transfers reliably when using
ddjvu; print-to-PDF routes may or may not carry it across, so the command-line method is preferable when searchable text matters. - Image quality is not degraded by the conversion -
ddjvure-encodes pages as images inside the PDF container without adding an extra compression pass.
