Before you start: Confirm these points first

  • Confirm whether the document is a text version or a scan. Open the PDF, use your mouse to select a piece of text and copy it. If it can be selected, it means that it is a text version; if it cannot be selected, the whole page is just a picture, which is probably a scanned copy. Both can upload translations, but the clarity of the original image of the scan will directly affect the quality of the translation. For blurry or skewed pages, it is recommended to change to a clear original first.
  • Check if the PDF has password or editing restrictions. If a file requires a password to open, the file owner should first unprotect it before uploading it for processing. Do not use any method to bypass the permissions set by others. This is not compliant and may also cause the file to be unable to be processed normally.
  • Think clearly about the purpose of the translation. Whether it is used for self-checking and citation learning, or whether it is submitted to others, directly determines whether to choose bilingual comparison or only translation. The uses are different and the focus of verification is also different.
  • Choose a stylistic style that matches your document. OmniDoc offers academic, legal, medical, technical, business, and literary styles. Choose academics for papers, law for contracts, and technology for instructions. If the writing style is right, the translation of professional terms will be more unified.
  • Try it first with the first few pages. For a 30-page paper or a 12-page contract, it is recommended to take the first few pages to verify whether the layout is as expected, and then process the entire document after confirming that there are no problems. When you need to modify the translation locally or export Word, you can download the desktop client from download.omnidoc.top.

Steps to translate an entire English PDF in OmniDoc

  1. Open omnidoc.top and enter the document translation function.
  2. Upload the original PDF. Try to upload the complete original file rather than taking a screenshot or just copying the text so that the layout information can be processed along with the file.
  3. Confirm that the translation direction is English to Chinese.
  4. Choose a style based on the type of document, such as academic, legal, technical, or business.
  5. Select the output method: if you want to read the text for comparison, choose bilingual comparison; if you want to read only the translation, choose translation only.
  6. Submit the translation and wait for the task to be completed before proceeding to the next step. Do not submit the same document again midway.
  7. Download the translation, open it and read the first two or three pages to confirm whether the layout is basically consistent with the original text.
  8. When local problems are found, modify the paragraph text in the PDF editor on the desktop client; when tables or formulas need major changes, export them to Word and then adjust them manually.

Check each item after completion

After getting the translation, it is recommended to check it in the following order, looking at the structure first and then the details.

Check itemsHow to seeWhat to do if there is a problem
Page number and page orderCompare the total number of pages of the original text and the translated text, and check whether the middle pages are coherentIf the number of pages is inconsistent, check whether the original text is uploaded completely and resubmit it if necessary.
FormCheck whether the rows and columns are aligned, whether the merged cells are retained, and whether the numbers are misplaced.Modify the text compared with the original text; derive Excel adjustment when there are many structural disorders
FormulaCheck the completeness of superscripts, fractions, Greek letters and symbolsManual correction against the original text, do not judge the meaning of the formula only by the translation
Pictures and annotationsWhether the picture is still on the original page, and whether the annotation corresponds to the correct picture.When the position is wrong, write down the page number and go back to the original text to confirm and then modify it.
Header, footer and page numberTurn to different pages to see if headers, footers and page numbers existThe missing or misplaced content should be added or modified in the PDF editor compared with the original text.
Terminology and key informationSpot check proper nouns, date, amount, dose, clause numberIf it is inconsistent with the original text, the original text shall prevail.

There will inevitably be omissions or misunderstandings in machine translation, especially the terms of the contract, data and drug descriptions. Be sure to go back to the original text one by one and submit it to someone who knows the profession to review if necessary.

# frequently asked questions (FAQ)

1. Can the scanned version of English PDF also retain the format?

Sure. Scanned pieces can be uploaded and translated directly, and the output will also retain layout, tables and pictures. The clearer the original picture is, the more stable the text recognition is and the more reliable the translation is. If you still need to edit locally, you can first OCR the scanned piece in the PDF editor on the desktop client.

2. How to choose bilingual control and translation only?

When you need to check the terms sentence by sentence, learn or quote the original text, choose bilingual comparison; if you only want to quickly understand the main idea, or when you want to print it to others, choose only the translation. You can try both outputs with the first few pages before deciding which one to use.

3. The table or formula in the translation is messy. Can you change it directly?

Sure. For simple text errors, modify the paragraph text directly in the PDF editor on the desktop client. When there is a lot of confusion in the structure of the table or formula, it is easier to export to Word and then adjust it manually.

4. Can the translated document be directly used as an official document?

It is not recommended to be used directly in formal occasions. Contract, paper contribution, drug description and other contents need to be manually checked paragraph by paragraph against the original text, and confirmed by people familiar with the field before use.
