About This Tool
DjVu was built for one job and does it well: compressing scanned pages far smaller than PDF could at the time. That is why digital libraries, university archives and Russian-language book collections are full of DjVu files - and why anyone who finds one needs a converter, since almost no mainstream software opens it.
Converting to PDF trades some file size for universal access. You control that trade-off through the DPI and quality settings: 300 DPI is right for printing, 150 for screen reading at a much smaller size.
Multi-page DjVu files convert to multi-page PDFs with page order preserved, which matters because most DjVu files in the wild are entire scanned books.

Use Cases

Library scans made accessible to readers with no specialist viewer.
Frequently Asked Questions
Why is the PDF bigger than the DjVu?
DjVu compression is unusually efficient for scanned text. PDF cannot always match it, so expect growth - lower the DPI if size matters more than detail.
Which DPI should I choose?
300 for printing or OCR. 150 for on-screen reading, which typically halves the file size.
Is the converted PDF searchable?
Not unless the DjVu carried a text layer. Run OCR PDF on the output to add one.
Are all pages converted?
Yes. Multi-page DjVu files convert page for page, in order.
