MarkDeck

MarkDeck is a fast, beautiful Markdown reader and editor that also reads PDF, EPUB and Word documents, and edits Word documents. Open any .md, .pdf, .epub or .docx file and read it your way, with your own themes, fonts and a clean, focused layout.

Whether you're a developer viewing README files, a student reading PDF notes, a writer keeping Markdown notes or a book lover with an EPUB library, MarkDeck makes reading a delight.

📖 MARKDOWN VIEWER THAT GETS EVERY DETAIL RIGHT

Tables scroll, code blocks have syntax highlighting, links are clickable and images display inline.

✍️ VISUAL MARKDOWN EDITOR

Edit Markdown like in a word processor: headings, lists, tasks, quotes, code, links, images and tables edited in place, with the Markdown view one tap away. Create new notes and save them to your library.

📄 PDF READER & 📚 EPUB READER

Open PDFs and EPUB e-books in the same calm reader. Read EPUB books with your theme, font and text size; read PDFs with comfortable zoom, Night and Warm modes (Pro) and password support.

📃 READ & EDIT WORD DOCUMENTS (DOCX)

Edit .docx files: fix a typo, rewrite a paragraph, add bold or italic. The file keeps its layout, tables and images.

Open .docx files as real pages: layout, headers and footers, tables, images and charts kept, with search and a table of contents from the headings. Export to PDF with Pro. Templates and macro-enabled files open too; macros never run.

💾 SAVE A COPY

Keep any document in your files with the system's save screen, no storage permission needed. The library copy stays as it is.

📝 FILL PDF FORMS

Fill in interactive PDF forms (text, checkboxes, options and lists) and save a copy while the original stays untouched.

🎨 20 READING THEMES

15 themes free: Light, Dark, Sepia, Paper, AMOLED, Dracula, Nord, Solarized, Gruvbox, Tokyo Night and more, plus 5 premium palettes with Pro.

🔤 YOUR FONTS & TEXT SIZE
