OmniReader Pro 3.4.4 Mac

A researcher opens a downloaded novel and finds pages of question marks instead of Chinese text. OmniReader Pro’s encoding handling sorts it in a click, making the file readable again.

Read and search anything

The app opens common book and document formats and includes both page search and full-text search. Forward and back reading history keeps your place without bookmarks.

Export to EPUB or PDF

Any loaded file can be exported as a new EPUB or PDF. Image size adjusts automatically during export so illustrations fit the destination format.

Check file details and fix garbled text

Basic file information—format, encoding, page count—is shown inside the app. For files that open with scrambled characters, OmniReader Pro offers encoding controls to restore the correct text.

Skipping the toolbar arrows means thinking the app lost your place

New users often overlook the reading history buttons, then complain the app “lost their place.” The forward and back arrows sit in the toolbar and work like a web browser — if you jump to a search result and want to return, tap back instead of scrolling blind.

Another common stumble is piling a dozen books into the sidebar and expecting a library. OmniReader Pro does not catalog; it opens files one at a time. Drag in what you need for the session and close it when you are done. Beginners also ignore the encoding menu when a Chinese EPUB opens as gibberish, then assume the file is corrupt. A quick trip to the encoding options usually fixes it.

Finally, the image extraction feature catches people off guard. It pulls every image into a folder — great for illustrated reference books — but someone who clicks it on a 600-page novel with a single cover image ends up wondering where all the “extracted” files went. There is just the one.

Yomu stumbles on CHM files where OmniReader Pro stays steady

Set OmniReader Pro beside Yomu and the difference comes down to focus. Yomu handles EPUB and PDF with a cleaner bookshelf view and a dark-reading mode that OmniReader Pro lacks, but it stumbles on CHM files — a format still common in technical documentation — which OmniReader Pro opens without complaint.

Clearview offers tabbed reading and a proper library with collections, putting it ahead for anyone managing a large, categorized shelf. However, Clearview does not export to EPUB, and its text-encoding controls are buried deeper. For a user who frequently receives files in uncertain encodings, OmniReader Pro’s upfront encoding handling saves real time.

Where OmniReader Pro stands apart is the combination of Kindle file support, CHM compatibility, and the one-click image extraction. Neither Yomu nor Clearview pulls all images from a document into a folder. If your reading crosses between novels, technical manuals, and illustrated texts, that trio of features matters more than a glossy library view.

A translator’s afternoon with OmniReader Pro

A literary translator receives three files from a publisher: a Chinese EPUB of a new essay collection, a CHM reference glossary compiled years ago, and a Kindle-format draft of the author’s earlier work for context. She opens all three in OmniReader Pro.

The EPUB arrives with scrambled chapter titles because the publisher’s export tool used the wrong encoding. She switches the encoding setting, the characters snap into place, and she begins reading. When a term trips her up, she opens the CHM glossary, searches for the phrase, and jumps back to the essay via the reading history. No second window, no separate app. Later, she exports the EPUB to PDF with the auto-adjusted image size so she can mark up the layout on a tablet. The afternoon stays inside one application.

Export no longer dumps oversized images off the page margins

As of version 3.4.4, the app tightened image size adjustment during export. Earlier builds sometimes left large illustrations overflowing the margins in the output PDF; now images scale down to fit the page width without manual tweaking — a fix that matters most when exporting illustrated non-fiction or children’s books.

Full-text search gained highlight persistence across page turns. Previously, a search term would highlight on the current page but vanish after advancing; now the highlight stays visible as you move forward, making it easier to scan a long chapter for every occurrence of a name or term. The sidebar collapse behaviour also became snappier, cleaning up a lag that appeared on older Intel Macs running macOS 10.13. For everyday reading, these changes mean fewer interruptions and less time spent re-running searches or resizing windows.
