A better home for your books
Folio is a local-first desktop app for reading and organizing the books you already own. EPUBs, PDFs, and comics stay on your machine, with the tools to read them comfortably and keep your library in order.
What Folio does well
Reading comfort first, library management second, and no push toward a store or cloud account.
EPUB, PDF, CBZ and CBR
Read reflowable ebooks, fixed-layout PDFs, and comic archives in one app. Dual-page spreads and manga mode included. Each format gets the viewer it needs.
Collections, tags and series
Keep your library usable as it grows. Build collections, add tags, group books by series, and sort by the things that actually matter when you're looking for something.
Highlights and bookmarks
Mark up what matters, add notes, and come back to it later without losing your place. Useful for actual reading, not just for checking a feature box.
OPDS catalog browsing
Browse sources like Project Gutenberg and Standard Ebooks, or connect your own OPDS catalogs. Find something, download it, and drop it straight into your library.
Metadata cleanup
Fix messy libraries without doing everything by hand. Folio pulls metadata, covers, and descriptions from Google Books, OpenLibrary, Comic Vine, and BnF automatically.
Reading stats
See how much you're actually reading: time spent, books finished, daily activity, and streaks. Useful if you like a bit of history without turning reading into a game.
Themes and typography
Reading comfort matters. Adjust fonts, spacing, margins, themes, and EPUB styling until the app feels right instead of just acceptable.
Multiple profiles
Keep different libraries separate when you need to. Each profile has its own books, progress, collections, and settings.
Remote access
Read from your phone, tablet, or another computer on the same WiFi. Folio runs a local web server with a browser-based reader and an OPDS endpoint for reader apps like KOReader.
Backup, restore, and sync
Export your library locally or back up to S3, FTP, SFTP, or WebDAV. Sync reading progress and bookmarks across devices through the same remote storage.
Why it feels different
Folio starts from a simple assumption: if your books are already yours, your reading app should not try to become a store, a subscription, or a cloud platform. It should be a good place to read and a sane place to keep your library.
Your files stay local. You can import by file, folder, URL, or drag-and-drop, read in paginated or continuous scroll mode, search inside EPUBs with Cmd/Ctrl+F, zoom into PDFs and comics, and come back later without losing your place. Want to read from your phone on the couch? The built-in web server lets you browse and read your library from any device on the same WiFi, and reading progress syncs across machines if you set up a remote storage provider. The point is not to do everything. The point is to do the important parts well.
