Sobre os arquivos MDComparativo de vantagens
DJVU Vantagens
- Extreme compression for scanned documents — typically 5-10× smaller than PDF.
- Preserves OCR text layer alongside scanned image.
- Mature archival format at Internet Archive, Wikipedia, academic libraries.
- Separate foreground/background layers compress each content type optimally.
MD Vantagens
- Readable as plain text even before rendering — fits in version control beautifully.
- Dead-simple: 90% of needs covered in 10 minutes of learning.
- Converts trivially to HTML, PDF, EPUB, and DOCX via Pandoc.
- Every modern IDE, note-taking app, and developer tool renders it natively.
- Lightweight — a typical Markdown file is kilobytes, not megabytes.
Limitações
DJVU Limitações
- No native browser support since the NPAPI era (~2015).
- Tooling outside Linux is sparse.
- Encoding requires the proprietary LizardTech/Caminova toolchain or djvulibre.
- PDF/JBIG2 now covers most of DjVu's use cases with wider compatibility.
MD Limitações
- No formal authoritative spec — CommonMark, GFM, and MultiMarkdown differ on edge cases.
- Tables and complex layouts are clunky; footnotes and math require extensions.
- Links to images stay external — no embedded media unless you base64-inline.
- Styling is limited to what HTML allows — custom branding requires CSS outside Markdown.

Upload the DJVU to KaijuConverter and pick DOCX, PDF, ODT, RTF, HTML, Markdown, or plain text. Our pipeline runs LibreOffice headlessly plus pandoc for text formats — the same engines behind professional document pipelines. Styles, tables, images, and hyperlinks survive the conversion intact.
Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to DJVU (frames, legacy macros) may flatten to static content in the target format.
