Before you start: Confirm these points first

Determine whether the PDF is a text version or a scanned copy. Open the file on your phone, try long pressing a piece of text and drag to select it. The text version can be selected; the scanned version cannot be selected and only full-page images can be seen. Both can be uploaded, but the clarity of the original scan will affect the quality of the translation. Once you have made a clear judgment, you will know where to look more when checking.
Confirm that the file can be opened normally. If the PDF has an opening password, you need to obtain the password from the file provider before opening it on your mobile phone. Files that cannot be opened cannot be uploaded for translation. You should first confirm that the file itself is intact.
Confirm that the network is stable. Both uploading and downloading require an Internet connection. When the file is large or the number of pages is large, it is recommended to operate under a stable wireless network and do not switch networks or exit the page midway.
Think clearly about the purpose of reading. If you just want to understand the general idea, you can choose translation only; if you want to quote, forward, or hand it over to others, you should choose bilingual comparison and check it paragraph by paragraph. The purpose of reading is different, and the final verification intensity is also different.
Be aware of the sensitivity of the document content. Before uploading contracts, medical records, and undisclosed information to the web page, you should first confirm that you have the authority to process these documents and understand the scope of use of the documents on the web page. When sensitive information is involved, you can first confirm with the provider whether online processing is allowed.

Steps to translate an entire English PDF in a mobile browser

Use the browser that comes with your phone to open omnidoc.top and enter the page related to document translation.
Select the English PDF to be translated from the phone storage or file application and complete the upload.
Confirm that the translation direction is from English to Chinese to avoid choosing the wrong language direction.
Select the output method: bilingual comparison or translation only, based on the judgment in the previous table.
If the page offers style options, select a field that matches the content of the document, such as academic, legal, business, or technical.
Submit the translation and wait for the page display processing to be completed. Processing time depends on file length and network conditions, while keeping the page open.
Download the translation to your mobile phone and open it with the usual PDF reading method.
If necessary, save the translation to a frequently used location, or send it to yourself so that you can view it at any time later.

Check each item after completion

Once you get the translation, don’t rush to forward or quote it. Go through the following items.

Check items	How to see	What to do if there is a problem
Number of pages	Compare the number of pages of the original text to see if the translation is complete	If the page is missing, re-upload and confirm that the original text itself is complete.
Layout	Whether the positions of tables, formulas and pictures are generally retained.	When the layout is abnormal, go back to the computer and open the original text and translation side by side.
Terminology	Are proper nouns and abbreviations consistent in the full text?	Write down inconsistent words and submit important documents to people familiar with the field for review.
Numbers and units	Whether the amount, date, dose and model are consistent with the original text	Check the original item by item, and the key figures must be confirmed.
Scanned piece identification	Is there any misreading of the person's name, number and small font size?	Go back to the original, zoom in and re-upload a clearer scan if necessary

It should be reminded that machine translation is bound to make errors, especially technical terms, negative sentences and long and difficult sentences. The translation can help readers understand the content quickly, but when it comes to important contents such as contract terms, medical information or academic citations, please check with the original paragraph by paragraph.

The OmniDoc translation retains the layout, tables, formulas and pictures. However, the screen of the phone is small, and typesetting may be crowded when reading, so you can put the phone horizontally to view tables and formulas.

3. What do you look at when choosing a free English PDF translation tool?

We should not only look at the price, but also pay attention to several practical problems: whether there is a limit on the size and number of pages of the file, whether the output result is watermarked, how to deal with and save the file after uploading, and whether the translation retains the layout and table. This information can usually be found in the description or terms of the page.

4. Can the results of the translation on the mobile phone be directly used in formal occasions?

The translation is suitable for quick understanding of the content. Before submitting materials, signing agreements or quoting academic opinions, key paragraphs and translations should be confirmed against the original text and, if necessary, be reviewed by a professional interpreter.

5. Why is the translation effect of the scanned version of PDF not as good as that of the text version?

The sharpness, tilt, shadow and blur of the original scan may affect the recognition. When you encounter an abnormal translation, you can first check whether the original is clear, and then decide whether to re-upload a clear scan.

Open OmniDoc, upload the document and start translation.
