UniReader for Mac brings many document formats into one calm, native reading experience— from PDF and EPUB to DjVu, comics archives, and more. You don’t need a separate app per file type, and you don’t need a cloud account just to open your own library.
Start here (fast wins)
- In-app manual. Open UniReader and use the built-in help: it’s written for real workflows—importing, themes, and annotations—and is available in every language we ship.
- Stay current. Install the latest UniReader from the Mac App Store and keep macOS reasonably up to date; many “it won’t open” reports come from very old system builds or one-off file quirks we’ve since improved around.
- One file, one test. If a specific document misbehaves, try another file of the same type. That quickly tells us whether it’s a format edge case or a broader issue.
We care about clarity: readable typography, sensible defaults, and tools that feel like they belong on macOS—Spotlight, tabs, and a reader that respects your privacy.
What UniReader is great at
For quick orientation, UniReader shines when you want to:
- Carry one reader instead of juggling multiple apps for PDF, EPUB, technical documents, and more.
- Organize a personal library with collections, search, and covers—without uploading your shelf to a server.
- Read comfortably with day/night themes, typography you control, and optional read-aloud where the format supports it.
- Annotate and pick up where you left off—reading position, highlights, and notes are kept with your library on this Mac.
UniReader on iPad and iPhone
UniReader for iPad and iPhone adds OPDS catalogs (free eBooks from Project Gutenberg, Wikisource, and compatible feeds) and optional iCloud sync for reading progress, highlights, and notes across your devices when you turn it on in the app. UniReader for Mac focuses on the desktop library and readers described above.
Contact the team
If the manual doesn’t answer your question, or you’ve hit something that feels like a bug, write to support@pasahome.org. We read every message; a bit of context helps us reply with something useful instead of guesswork.
Please include when you can:
- Your macOS version and UniReader version (from the App Store or About).
- What you were trying to do, and what happened instead—in one or two short sentences.
- If it’s file-specific: the format (e.g. PDF, EPUB) and, if possible, whether other files of the same type work.
