DjVu is a document format designed for scanned pages — it separates text, foreground, and background layers to compress scans far better than JPEG or TIFF. It was popular for digital libraries and archives, but few modern apps can open it.

Is my document uploaded anywhere?

No. The DjVu decoder runs as WebAssembly inside your browser. Your file is decoded, rendered, and converted entirely on your device.

Which DPI should I choose?

72 DPI for a compact file meant for screens, 150 DPI for a balance of size and clarity, and 300 DPI when you plan to print or need maximum detail.

Will the PDF have searchable text?

No — the output is image-only, even when the DjVu contains a hidden text layer. Run the PDF through the OCR PDF tool to make it searchable.

Why did my .djvu file fail to load?

Only bundled single-file DjVu documents are supported. Indirect DjVu — an index file that references separate page files — needs its companion files, which a browser cannot fetch from your disk.

Does it work on multi-page documents?

Yes. Every page is rendered and embedded in order, so a multi-hundred-page scanned book becomes a multi-hundred-page PDF.

Can I convert DjVu on my phone?

Yes — the decoder runs in any modern mobile browser. Large documents may take a while since every page is rendered locally.

About DjVu to PDF

How DjVu to PDF Conversion Works

DjVu was built for scanned documents: it compresses text and imagery far better than JPEG, which is why so many scanned books and archive collections live in .djvu files. The catch is that almost nothing else can open them. This tool decodes the document with a WebAssembly DjVu engine, renders every page to a bitmap at the resolution you choose, and embeds each render as a JPEG page in a PDF.

The whole pipeline runs in your browser. A 500-page scanned book never touches a server — decoding, rasterizing, and PDF assembly all happen on your device.

Why Convert DjVu to PDF

DjVu compresses brilliantly but opens almost nowhere. PDF opens everywhere.

Archive Documents

Library and archive scans in DjVu become ordinary PDFs that any device, reader, or document system can open.

Share Scanned Books

Send a scanned book to someone without asking them to install a DjVu viewer first. PDF is the format they already have.

Print Preparation

Render at 300 DPI for output that holds up in print, or 72 DPI for a compact file meant for screens.

Private by Design

Scanned documents are often sensitive — contracts, archives, personal records. Conversion is 100% local with zero uploads.

Resolution and Quality

The DPI setting controls how many pixels each page is rendered at: 72 DPI produces the smallest file for on-screen reading, 150 DPI is the balanced default, and 300 DPI preserves fine detail for printing. Each PDF page keeps the document's physical dimensions, so a page scanned at letter size stays letter size.

JPEG quality trades file size against image fidelity on the rendered pages. The default 85% is a good middle ground for scanned text; raise it for documents with photographs or fine line art.

The Output Is Image-Only

The PDF contains rendered page images — it is not searchable and text cannot be selected, even if the original DjVu carried a hidden text layer. To get searchable text, run the result through the OCR PDF tool afterwards.

Only bundled single-file DjVu documents are supported. Indirect DjVu files — where an index file references separate page files — cannot be resolved because the companion files are not available to the browser.
