DjVu (pronounced "déjà vu") came out of AT&T Labs in the mid-1990s with one goal: make scanned pages small enough to download over a dial-up modem. It worked. A 300-page scanned technical manual that would balloon to 200MB as a PDF might sit at 15MB in DjVu — sometimes less.
The trick is layer separation. DjVu splits each scanned page into a sharp black-and-white text mask and a low-resolution background layer, then compresses each with a codec tuned for that kind of data. Text stays crisp. Paper texture and photos get squeezed hard. Your eye barely notices.
That's why you'll still find DjVu all over academic archives, Russian and Eastern European scientific libraries, old engineering handbooks, and public-domain scanning projects. Here's what defines the format:
PDF is the closest thing the document world has to a universal language. Adobe published the spec, ISO standardized it (ISO 32000), and now every operating system, browser, phone, printer, and e-reader can open a PDF without installing anything.
Concretely, moving from DjVu to PDF buys you:
The process is straightforward — no software install, no account required for a single file.
1. Upload your file. Drag the .djvu (or .djv) file onto the drop zone, or click to browse. Uploads are capped at 10MB. DjVu compresses aggressively, so many scanned books fit — but long or high-resolution scans can still exceed the limit.
2. Wait for processing. A 50-page document is usually done in under 15 seconds. A 600-page scanned encyclopedia can take a couple of minutes — the converter has to decode and re-encode every single page image.
3. Download the PDF. One file, pages in the original order, ready to open anywhere.
A few things worth knowing before you start. If your DjVu came from a library scanning project, check whether it has a text layer — open it in a DjVu viewer and try Ctrl+F. If search works, you'll get a searchable PDF. If it doesn't, you'll get an image-only PDF, and you'd need a separate OCR pass to make it searchable.
Also: don't rename a .djvu to .pdf and hope. That's not how file formats work. The bytes inside are completely different.
Most people converting DjVu aren't format enthusiasts — they hit a wall and need a way around it. The usual walls:
You downloaded a book from an archive and can't open it. Internet Archive, library digitization projects, and older academic repositories still serve DjVu. You grabbed the file, and nothing on your laptop knows what to do with it.
You need to print it. Print shops want PDF. Campus printers want PDF. Your office copier's USB port wants PDF.
You want it on an e-reader or tablet. No Kindle, Kobo, or iPad reads DjVu natively. PDF works on all of them.
You need to annotate for research. Highlighting a scanned paper for your literature review requires a tool that reads the file. PDF annotation tools are everywhere; DjVu annotation tools are a short and dusty list.
You're sending it to someone else. Emailing a DjVu is a good way to get a reply asking "what is this file?" PDF avoids that conversation entirely.
You're archiving long-term. DjVu support has been quietly shrinking for years. Converting now means you can still read it in ten years.
Neither format is strictly better. They were built for different eras and different problems.
| Feature | DjVu | |
|---|---|---|
| File size (scans) | Excellent — very small | Larger, often 3-6x |
| Native OS support | ❌ Needs a plugin | ✅ Built in everywhere |
| Browser viewing | ❌ No | ✅ Yes |
| Mobile support | ❌ Third-party apps only | ✅ Native |
| Printing | ❌ Awkward | ✅ Standard |
| Annotations | ❌ Minimal | ✅ Full |
| Text search | ✅ If OCR layer exists | ✅ If OCR layer exists |
| Standardization | Informal spec | ISO 32000 |
| Best for | Storing huge scan libraries | Reading, sharing, printing |
Only if the original DjVu file already had an OCR text layer — the converter carries that layer through into the PDF. If the DjVu is pure images with no hidden text, the PDF will be pure images too, and you would need a separate OCR step to make it searchable.
DjVu uses a specialized layered compression built specifically for scanned pages, and PDF has no direct equivalent. A 3-6x size increase is completely normal, and for very image-heavy documents it can be more.
Yes. Entire multi-page documents convert into a single PDF with pages in the original order. Long books with hundreds of scanned pages take a few minutes because every page image has to be decoded and re-encoded.
Yes — 10MB per file. DjVu is efficient enough that many scanned books fit under that, but long or high-resolution scans can exceed it. For those, convert locally with a desktop tool.
The page images are carried over at their original resolution, so what you see in the DjVu is what you get in the PDF. Any softness or artifacts you notice were baked into the original scan by DjVu compression, not added during conversion.
Absolutely. All files are transferred over 256-bit TLS (SSL) encrypted connections. Your original file and converted file are automatically deleted from our servers within 1 hour. We never read, store, or share your content.
Deepen your understanding with expert conversion guides:
Lost digital libraries are a nightmare for any avid reader. You might have stumbled upon a rare technical manual in the old LIT format, found a classic literary anthology in DJVU, or inherited a collection of Russian literature in FB2. For years, these formats ruled the early internet book-sharing scene, but as technology moved forward, support for them faded. Now, you likely find yourself stuck with files that your modern e-reader, tablet, or phone cannot open natively. The solution is not to start over from scratch; it is to convert. Whether you need to move your old LIT files to the universal EPUB standard, compress DJVU archives into readable PDFs, or simply clean up the formatting of an old FB2 file, modern conversion tools like BookConv make this process seamless. This guide will walk you through why these legacy formats are problematic today and how you can quickly rescue your digital reading experience across LIT, DJVU, FB2, and RTF files.
Stuck with a DjVu file you can't open? Converting DjVu to PDF is the fastest way to make that scan readable anywhere. DjVu was built in the 1990s to shrink scanned books to almost nothing, but barely anything reads it natively today. This guide shows you how to convert DjVu to PDF in a few clicks, why the PDF ends up bigger, and the one case where you should not bother.
A scanned PDF is just a pile of page images — there is no real text inside, so it cannot reflow or be searched. To turn it into a proper EPUB, you need OCR (optical character recognition) to read the words out of the images first. Here is how the process works and what to expect.
Format explainers and in-depth comparisons:
You have a scanned book in DJVU that no reader app opens and no one can print. Converting DJVU to PDF makes it readable everywhere. Here’s how to do it free with BookConv in your browser, no software to install, without losing quality.
Your EPUB looks perfect in a reader but turns into a messy PDF — odd page breaks, shifted images, missing fonts. Here is why, and how to fix it.
You have a comic in CBR that your reader app will not open. Converting CBR to PDF makes it viewable everywhere. Here is how to do it without losing pages.
