As that niche is also the primary usage for PDF, it was inevitable that the two formats would become competitors. It should however be observed that the two formats approach the problem of delivering high resolution documents in very different ways: PDF primarily encodes graphics and text as vectorised data, whereas DjVu primarily encodes them as <a href="/wiki/Pixmap" class="mw-redirect" title="Pixmap">pixmap</a> images. This means PDF places the burden of <a href="/wiki/Rendering_(computer_graphics)" title="Rendering (computer graphics)">rendering</a> the document on the reader, whereas DjVu places that burden on the creator. </p><p>During a number of years, significantly overlapping with the period when DjVu was being developed, there were no PDF viewers for free operating systems—a particular stumbling block was the rendering of vectorised fonts, which are essential for combining small file size with high resolution in PDF. Since displaying DjVu was a simpler problem for which free software was available, there were suggestions that the <a href="/wiki/Free_software_movement" title="Free software movement">free software movement</a> should employ DjVu instead of PDF for distributing documentation; rendering for creating DjVu is in principle not much different from rendering for a device-specific printer driver, and DjVu can as a last resort be generated from scans of paper media. However, when <a href="/wiki/FreeType" title="FreeType">FreeType</a> 2.0 in 2000 began to provide rendering of all major vectorised font formats, that specific advantage of DjVu began to erode. </p><p>In the 2000s, with the growth of the <a href="/wiki/World_Wide_Web" title="World Wide Web">World Wide Web</a> and before widespread adoption of <a href="/wiki/Broadband" title="Broadband">broadband</a>, DjVu was often adopted by <a href="/wiki/Digital_library" title="Digital library">digital libraries</a> as their format of choice, thanks to its integration with software like <a href="/wiki/Greenstone_(software)" title="Greenstone (software)">Greenstone</a><sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> and the <a href="/wiki/Internet_Archive" title="Internet Archive">Internet Archive</a>,<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> browser plugins which allowed advanced online browsing, smaller file size for comparable quality of book scans and other image-heavy documents<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup> and support for embedding and searching full text from <a href="/wiki/Optical_character_recognition" title="Optical character recognition">OCR</a>.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> Some features such as the thumbnail previews were later integrated in the Internet Archive's BookReader<sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> and DjVu browsing was deprecated in its favour as around 2015 some major browsers stopped supporting <a href="/wiki/NPAPI" title="NPAPI">NPAPI</a> and DjVu plugins with them.<sup id="cite_ref-ia2016_18-0" class="reference"><a href="#cite_note-ia2016-18"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> </p><p>DjVu.js Viewer attempts to replace the missing plugins. </p> <div class="mw-heading mw-heading2"><h2 id="Technical_overview">Technical overview</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=DjVu&action=edit&section=3" title="Edit section: Technical overview"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="File_structure">File structure</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=DjVu&action=edit&section=4" title="Edit section: File structure"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The DjVu file format is based on the <a href="/wiki/Interchange_File_Format" title="Interchange File Format">Interchange File Format</a> and is composed of hierarchically organized chunks.

To create a DjVu file, the initial image is first separated into three images: a background image, a foreground image, and a mask image. The background and foreground images are typically lower-resolution color images (e.g., 100 dpi); the mask image is a high-resolution bilevel image (e.g., 300 dpi) and is typically where the text is stored. The background and foreground images are then compressed using a <a href="/wiki/Wavelet_compression#Wavelet_compression" class="mw-redirect" title="Wavelet compression">wavelet-based compression</a> algorithm named IW44.<sup id="cite_ref-djvupaper_5-2" class="reference"><a href="#cite_note-djvupaper-5"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The mask image is compressed using a method called JB2 (similar to <a href="/wiki/JBIG2" title="JBIG2">JBIG2</a>). The JB2 encoding method identifies nearly identical shapes on the page, such as multiple occurrences of a particular character in a given font, style, and size. It compresses the bitmap of each unique shape separately, and then encodes the locations where each shape appears on the page. Thus, instead of compressing a letter "e" in a given font multiple times, it compresses the letter "e" once (as a compressed bit image) and then records every place on the page it occurs. </p><p>Optionally, these shapes may be mapped to <a href="/wiki/UTF-8" title="UTF-8">UTF-8</a> codes (either by hand or potentially by a <a href="/wiki/Text_recognition" class="mw-redirect" title="Text recognition">text recognition</a> system) and stored in the DjVu file.
