Scenario: Reading an English e-book on the commute

Suppose you have an English technical book or a 30-page English report, and the file is saved on your computer. You want to read the Chinese translation on your mobile phone on the subway, and at the same time refer to the original text when necessary.

There are usually three reasons for getting stuck: there is no corresponding software on the mobile phone, the file cannot be found after being transferred to the mobile phone, and the translation cannot be opened on the mobile phone after downloading or the layout is disordered. The following process addresses these issues in order.

Complete process

Confirm the file format. E-books are generally EPUB or PDF, both can be uploaded. The file name suffix can be viewed on the computer or in the mobile file management.
Put the file locally on the phone. It can be transmitted using a data cable, or it can be sent to the mobile phone through the file transfer function of cloud storage or chat software, and then saved to the file directory of the mobile phone.
Open omnidoc.top with your mobile browser, and enter the document translation function. Mobile browsers can generally be used directly without the need to install additional applications.
Upload e-book. Find the file you just saved in the file selection interface of the browser, select it and upload it. Try to keep the page in the foreground during the upload to avoid upload interruption caused by switching applications midway.
Select the output method. If you want to compare the original text while reading, choose bilingual comparison; if you just want to read it in full, choose translation only.
Wait for the processing to complete before downloading the translation. The downloaded file will be saved to the download directory of your phone, please remember the save location.
Open the translation with a reader. EPUB can be opened with a reader on your mobile phone that supports this format, and PDF can be opened with the system's built-in viewer. If a certain reader cannot open it, just change it to a reader that supports that format.
Randomly check the translation. After translation, select a few important paragraphs and compare them with the original text to see whether the meanings of professional terms, names, numbers and key sentences are accurate.

Where things can easily go wrong

The file cannot be selected on the mobile phone. The method of discovery is that the e-book cannot be found in the file selection interface, or only the most recent photos are displayed. The solution is to download or copy the e-book to the local phone and then upload it again.

Text cannot be copied from the scanned PDF. Press and hold a piece of text on your phone to try to select it. If you cannot select it, it usually means it is a scanned copy. The scanned PDF can be directly uploaded for translation without additional processing. However, if the scanning quality is poor, the translation may contain typos and needs to be carefully checked.

It took a long time to upload but no result. When the file is large or the network is unstable, the progress may be stalled for a long time. You can confirm the network connection first, and if necessary, move to a place with a more stable signal and upload again.

The translation is formatted incorrectly on the mobile phone. Complex layouts, tables and formulas are prone to incomplete display on small screens. In this case, you can open the translation check on your computer to confirm whether the original layout is retained.

Terminology is inconsistent, or sentences read awkwardly. Machine translation inevitably contains inaccuracies, especially technical terms and long and difficult sentences. You can choose a style that matches the type of text when translating, such as academic, technical, or legal, and reduce inconsistencies with the terminology consistency feature. Important content must still be checked against the original text.

🎯 Which method is suitable for you?

If you just want to read one or two English books occasionally

Open the web version directly in your mobile browser, select translation only after uploading, and download it to your mobile phone for reading. There is no need to install any software.

If you need to read and refer to the original text

Select bilingual comparison output, the original text and the translation are arranged side by side, making it easier to compare paragraph by paragraph when reading on the mobile phone's horizontal screen.

If you have a scanned PDF

Just upload the translation directly without having to find other tools to recognize the text first. After uploading, focus on checking numbers, formulas and professional terms.

If you need to process a large number of files for a long time, or need to modify the translation

Download the desktop client from download.omnidoc.top on your computer to process files and modify PDF paragraph text, which is more efficient than mobile browsers.
