How to convert DjVu to PDF
- Add your
.djvuor.djvfile. Every page is listed, so you can see what you are working with before converting anything. - Pick the pages you actually need. A whole scanned book makes a large PDF, so exporting a chapter is often the better move.
- Reorder or drop pages if you want. Nothing you do here changes the original file.
- Press Export PDF. One page comes back as a single PDF; several pages come back as one PDF containing them in the order shown.
What the PDF keeps — and what it doesn't
DjVu pages are brought in as visual pages. The exported PDF preserves how each page looks, its page size and the page order. A document whose pages are different sizes stays that way; nothing is stretched to a uniform A4.
It does not carry over the text layer. Many scanned DjVu files contain OCR text behind the image, and that text is not preserved in the PDF — the result is not a searchable PDF, and you will not be able to select or copy words from it. DjVu bookmarks, hyperlinks and annotations are not preserved either.
If searchable text is what you actually need, this tool is the wrong one: convert for reading, printing or sharing, and run OCR separately afterwards.
Why the PDF is bigger than the DjVu
DjVu compresses scanned pages far more aggressively than PDF does, so the file almost always grows. In our own measurements a 520-page, 25 MB scanned book became a roughly 120 MB PDF, and a short illustrated book grew about tenfold.
That is a property of the two formats, not a setting you can flip here. It is also why the page picker matters: exporting the ten pages you need keeps the result in the single-digit megabytes, while exporting a whole book produces a file that is slow to make and slow to send.
Everything happens on your device
The DjVu decoder runs inside your browser as WebAssembly. Your file is read locally and the PDF is written locally — nothing is uploaded to a server, and there is no account to create.
That also means the work is done by your own device. A large book takes a while to convert, and a phone will take noticeably longer than a laptop.
