OmniReader — EPUB, PDF, CBZ & DjVu

All-in-one offline reader for EPUB, PDF, comics (CBZ/CBR), FB2 & DjVu. No uploads, no tracking.

OmniReader is an all-in-one reader for Chrome. It opens ebooks, documents, comics and scanned books directly in a browser tab, so you don't need a separate application for each type of file. Supported file types are EPUB/PDF and DjVu. Ebooks open with a chapter table of contents, scanned documents render page by page, and comic archives open in a dedicated view with page thumbnails, a single-page or grid layout, and support for right-to-left reading. Reading settings include light, dark and sepia themes and adjustable text size. You can highlight and tag regions of a page with colored rectangles. OmniReader remembers where you stopped and lets you reopen recent files with one click. Everything happens on your device. Files are never uploaded, there is no server component, no analytics and no tracking, and the extension works without an internet connection. No account is required. The extension is free, contains no advertising, is built on Manifest V3 and requests only the storage permission. To start reading, open the toolbar popup and either drag a file onto it or click to browse for one.
