D.S.Reader vs FolioBind

E-Book Reader supporting EPUB, PDF, and CBZ formats, with custom fonts and custom dictionary support. When paired with calibre Content Server, you can easily browse your libraries, download books for reading. It will track and sync you reading progress and highlights across all devices paired with the same server.

FolioBind turns the files already on your device into real EPUB ebooks — and fixes the EPUBs you already have. CONVERT ANYTHING Import TXT, Markdown, DOCX, PDF, CBZ, ZIP or CBR and FolioBind builds a proper EPUB. TXT and Markdown get chapter-aware reflowable text with an automatic table of contents. Flip horizontal text into vertical right-to-left layout and back — ideal for Chinese, Japanese and Korean. Image references in your text — a local file path or a direct link — are fetched and embedded automatically, no manual attaching required. PDF pages and comic archives (CBZ/ZIP/CBR) become fixed-layout books that keep your original page art. DOCX text and images convert to clean reflowable EPUB. Queue a whole folder and convert it in one batch. EDIT AND REPAIR EPUBS YOU ALREADY HAVE Point FolioBind at any EPUB and it inspects the file, tells you exactly what's wrong, and fixes it: rebuilds a broken container or manifest, repairs the table of contents, upgrades EPUB2 files to EPUB3, embeds remote images, strips embedded fonts, and edits metadata — title, authors, series, subjects, identifiers, rights, publish date and reading direction. TYPOGRAPHY YOU CAN SEE BEFORE YOU SAVE A live preview renders your real content with the exact CSS FolioBind writes into the EPUB, so line height, paragraph spacing, first-line indent, margins and vertical right-to-left layout are all judged by eye, not by number. BUILT FOR YOUR LIBRARY Automatically convert images to JPEG and downsize them to save storage space, without touching your originals. Quickly convert between Simplified and Traditional Chinese offline. Generate a fresh source copy instead of overwriting your files. Share finished books straight to Apple Books, Kindle, Mail or any app that accepts EPUB. PRIVATE BY DESIGN Everything happens on your device. No account, no upload, no server round-trip — your files never leave your iPhone or iPad. Free includes one conversion per day and the full editing and repair toolset. FolioBind Pro removes the daily limit and unlocks batch conversion, available as a monthly subscription or a one-time lifetime purchase.
