Free online DJVU to PNG converter

A document viewer, editor, or mobile app may not open DJVU, while PNG is accepted by most image software and browsers. Converting the pages creates shareable image files, but a multi-page document normally produces one PNG per page.

What the DJVU format is

DJVU is a document format designed for scanned books, manuals, newspapers, and archival documents. It compresses page components separately, including backgrounds, foreground line art, and an optional text layer, so scanned pages can be considerably smaller than equivalent uncompressed images.

DJVU files are common in digital libraries, scanning collections, and document repositories. DjVuLibre, WinDjView, and other dedicated viewers can open them, but support is limited in general-purpose image editors, office applications, and mobile software.

What the PNG format is

PNG is a lossless raster-image format supported by web browsers, operating systems, office software, and image editors. It preserves the pixels produced during rendering without adding JPEG-style compression artifacts, which makes it suitable for text, line art, screenshots, and further editing.

PNG is an image format rather than a document container. It does not retain DJVU's searchable text layer, bookmarks, navigation, or multi-page structure, and a rendered PNG is often much larger than the source file.

How to convert a DJVU file to PNG

Using 101convert.com:

1. Open the DJVU conversion tool on 101convert.com.
2. Select or upload the .djvu file.
3. Choose PNG as the output format and start the conversion.
4. Download the resulting PNG file or files. A multi-page source may be returned as separate images or as a downloadable archive.

This option requires no installed software and is suitable for occasional conversions. Do not upload confidential, copyrighted, or legally restricted documents to an online converter unless its handling terms meet your requirements.

Using DjVuLibre locally: DjVuLibre includes the ddjvu command-line renderer for Windows, macOS, and Linux. To render page 1, run:

ddjvu -format=png -page=1 input.djvu page-1.png

Change input.djvu and page-1.png to the required filenames. Render another page by changing the page number:

ddjvu -format=png -page=2 input.djvu page-2.png

To render at twice the default scale, use:

ddjvu -format=png -page=1 -scale=2 input.djvu page-1.png

Repeat the command for each page that is needed. Rendering locally avoids uploading the source and gives direct control over page selection and output size. A DJVU viewer may also offer page export, but a screenshot can use the viewer's display resolution and may include interface elements.

Quality and compatibility limitations

Conversion rasterizes the selected page; it does not recover detail that was absent from the scan. Use the source resolution when possible. For ordinary text pages, approximately 200–300 DPI is often sufficient, while small type, fine line drawings, or technical diagrams may require a higher scale.

PNG compression is lossless only after rendering. If the DJVU contains a low-quality or heavily compressed scan, the PNG will preserve that existing limitation rather than improve it.

Export one PNG per page when the document has multiple pages. If a single file must retain page order, searchable text, or navigation, keep the DJVU or create a searchable PDF instead; ordinary PNG does not store those document features.
