How to convert DjVu to JPG
- Add your .djvu or .djv file. Pages appear as thumbnails as they are decoded, so you can find the ones you want without opening the book elsewhere.
- Leave Export as on JPG and set the Quality you want.
- Tick the pages you need. For a scanned book this matters — a few pages is a normal request, a whole volume is a very large export.
- Press Export. A single page downloads as one JPG; several pages arrive as a ZIP, numbered in page order.
Why DjVu files need converting at all
DjVu was designed for one job and does it unusually well: storing scanned books and documents at a size that was practical to distribute. A several-hundred-page volume can fit in a few dozen megabytes with the text still legible — something no general-purpose image format manages.
The cost is that almost nothing opens it. Browsers do not display DjVu, phones generally do not, and sharing a page with someone usually means asking them to install a dedicated reader first. Exporting the pages you need as JPG is how a page from an archive becomes something you can put in a message, a slide or a document.
Each page becomes its own image
- One page selected → one JPG, downloaded directly.
- Several pages → one JPG each, delivered as a ZIP.
- The whole book → possible, but consider PDF instead, or export in batches.
A JPG file holds exactly one image, so a book cannot become a single JPG — each page becomes its own file, named in page order and delivered as a ZIP when there is more than one.
It is worth being deliberate about how many pages you pick. Exporting six pages from a reference book is quick; exporting six hundred means six hundred full-resolution images, and that is a lot of work for your device and a lot of files at the other end. If you want the pages kept together in one document, export as PDF instead — it is in the same dropdown.
What comes across, and what does not
- The page as an image: yes. Each exported JPG shows the page as it appears in the document.
- Text you can select or search: no. Many DjVu files contain a recognised text layer from the original scanning, and that layer is not exported. A JPG is a picture of the page; the result is not searchable, not selectable and not editable.
- Bookmarks, links and page labels: no. These are document structure, and an image file has nowhere to keep them.
- JPG is lossy: each page is re-encoded at the quality you choose. On bitonal scans — black text on white — low quality settings show up as grey haze around the letters, so keep quality high for text pages or export as PNG instead.
- Transparency: JPG has none. Nothing in a scanned page normally needs it.
- Multi-file DjVu: indirect documents, where the pages live in separate files alongside an index, are not supported. You get a message saying exactly that rather than a false report of damage.
Questions
Is my file uploaded?
No. The DjVu is read from your disk into your browser's memory and decoded there by a local engine. Nothing is sent to a server, so there is no server-side copy to delete afterwards.
Will the exported pages be searchable?
No. The exported files are JPG images — pictures of the pages. Any text layer the DjVu carried is not part of the export, so the result cannot be searched, selected or edited.
My book has 400 pages. Do I get 400 files?
If you select all 400, yes — one JPG per page, in a ZIP. That is a lot for a browser to produce in one go. Pick the pages you actually need, or export as PDF if you want the whole thing in one document.
The text looks fuzzy around the edges. Why?
That is JPG doing what JPG does with sharp black-on-white edges. Raise the quality setting, or export those pages as PNG instead — PNG is lossless and much better suited to bitonal scans.
Why can it not open my DjVu?
The most common reason is an indirect document: a DjVu that references other files it was distributed with, rather than containing every page itself. That case is reported as what it is. A genuinely damaged file gets a different message, so the two are never confused.
Should I choose JPG or PNG?
JPG for photographic or illustrated pages, where its compression is efficient and the loss is hard to see. PNG for plain text and line art, where it stays crisp and often comes out smaller than a high-quality JPG of the same page.
