OmniReader Pro 3.4.4 for macOS

It's like the bookmarks bar in your web browser, but for your entire library. OmniReader Pro keeps your reading list tidy without the fuss.

• Supported file types — EPUB, CHM, and Kindle files are all fair game.
• macOS needed — Version 10.13 or newer, and it runs natively on both Intel and Apple Silicon Macs.
• Interface languages — English and Chinese (Simplified).
• Key reading tools — Page turning, zooming, and a collapsible sidebar for a cleaner view.
• Search smarts — Highlights your search terms so nothing gets lost on the page.
• Extra tricks — Pull out every image to a single file, print pages directly, or export your books to EPUB and PDF.

A typical reading session, step by step

I grabbed a CHM manual I'd been meaning to work through for weeks. You know how it goes — the file sits there on the desktop, staring at you. Double-clicking it launched OmniReader Pro instantly. No splash screen, no setup wizard, just the book.

The sidebar sat on the left with a clean table of contents. I collapsed it right away with the little toggle button — I wanted the full page in front of me, no distractions. Page turning was a tap on the arrow keys, and the zoom slider in the corner let me bump the text up just enough that I could lean back in my chair instead of hunching forward.

About twenty pages in, I remembered a term the author had used earlier. I hit Cmd-F, typed "buffer overflow," and watched the search panel light up. Every match on the current page got a yellow highlight. The forward and back arrows in the search bar let me jump between results without losing my place — the app kept a reading history, so I could always backtrack to where I'd been before the search.

When I finished the chapter, I printed two pages directly from the File menu. Clean output, no cut-off margins. Then I exported the whole thing as a PDF to stash in my reference folder. The whole session felt like working with a paperback and a highlighter, except faster and without the coffee stains.

Skipping the sidebar kills navigation

The first thing people do wrong with OmniReader Pro is ignore the sidebar entirely. They treat it like a PDF viewer and just scroll endlessly, not realizing the table of contents is sitting right there for quick jumps between chapters. Tap the sidebar toggle and save yourself the wrist strain.

Another common slip-up: opening a file with garbled text and assuming the app can't handle it. Nine times out of ten, it's an encoding mismatch. The app has a file encoding handler buried in the menu — switch from UTF-8 to GBK or whatever the original encoding was, and the scrambled characters snap back into place. Beginners rarely poke around for that setting.

People also forget the image extraction feature exists. You can pull every illustration, diagram, and cover image out of an EPUB or CHM file into a single folder with one command. Handy when you're compiling notes or presentation slides. Don't screenshot individual pages — let the app do the heavy lifting.

Lastly, the search history trips people up. They search for something, click around, then can't find their way back to the page they were reading before the search. The back button in the toolbar handles that — just like a browser. Use it.

Export straight to Preview or Apple Books

OmniReader Pro slots into a Mac workflow without demanding attention. Export to PDF and the file drops right into Preview, ready for annotation or signature. Export to EPUB and you can hand the file off to Apple Books or send it to an iPad for couch reading later. The app isn't trying to be your only reader — it's the translator between formats.

For researchers and writers, the image extraction feature pairs well with Notes or Bear. Pull all the diagrams from a technical EPUB, drag them into a note, and you've got a visual reference sheet without hunting through pages. If you're working with CHM documentation — still common in open-source projects — OmniReader Pro handles what Safari and Preview won't touch.

The printing support plays nice with macOS system dialogs too. You get the standard paper size, orientation, and scale options you'd expect, and Save as PDF is right there in the print dialog as usual. For anyone who keeps a digital filing cabinet in Finder, that's the smoothest path from "I read this" to "I saved this where I'll actually find it later."

It also respects standard Mac keyboard conventions. Arrow keys for page turning, Cmd-plus and Cmd-minus for zoom, Cmd-F for search. No weird custom shortcuts to memorize. If you use omni reader pro alongside a reference manager or a plain-text note system, the rhythm stays predictable — read, extract, export, file away.

Bottom line: if your Mac can handle High Sierra or later, you're all set.
