OmniDocHow to translate scanned PDF into editable Word document
Scanned PDFs cannot directly copy text. This article explains the complete process of first using OCR to recognize text, then translating it, and finally exporting it to editable Word. It also provides judgment methods and a finished product checklist before starting.
Key points of this article
- First determine whether the PDF is a scan: If you can select and copy text, it is not. If you cannot select or copy garbled characters, you need to do OCR first.
- It is recommended to OCR the scanned document first and then export it to Word. The recognition result can be edited and then translated, which reduces the modification cost.
- When you only need translation and no modifications, you can directly upload the scanned PDF for translation, with fewer steps.
- The exported Word needs to check numbers, proper nouns, tables and formulas item by item against the original, and both machine translation and OCR may make errors
Many people have a scanned PDF in their hands, such as a paper contract synthesized from photos, pictures of handouts sent by teachers, and photocopied pages of foreign documents. I wanted to translate it into Chinese and change it into Word, but I found that the mouse could not select any text, and the copied text was either blank or garbled. This kind of document cannot be directly converted to ordinary PDF to Word.
This article talks about this situation: how to translate pdf documents into word, the key is to first make the text in the picture "alive". The process is divided into three steps: first use OCR to recognize the text, then translate it, and finally export it to editable Word. The PDF editor of the OmniDoc desktop client supports OCR and exporting to Word, and document translation also supports Word (.docx) and scanned PDF. This is explained below.
After reading, you can judge which way to go with the document in your hand, follow the steps, and know what to check after getting the results. If you are looking for a document translation PDF to Word tool, you can also refer to the following selection criteria.
How to translate scanned PDF into Word? One sentence conclusion
For scanned documents, the text in the image must be recognized first, and then exported to Word for translation and modification. Do not skip the recognition and convert directly. If you only need translation and do not plan to change it again, you can directly upload the scanned PDF translation.
| your situation | Recommended practices | reason |
|---|---|---|
| Just a Chinese translation, no modifications required | Upload scanned PDF directly and choose translation only or bilingual comparison | Fewer steps, layout will be retained |
| After the translation comes out, it has to be revised and supplemented. | First OCR, export Word, and then translate Word documents | Word can be edited paragraph by paragraph, and the modification cost is low |
| PDF can select text | Skip OCR and export Word or translation directly | There is already a text layer and does not need to be recognized. |
| Reports whose files are mainly tables | Export to Word or Excel and check table by table | Table misalignment is a common problem |
| Papers containing a lot of formulas | Check the formulas one by one after exporting Word | The identification formula is prone to errors and requires manual verification. |
Before you start: Confirm these points first
- Determine whether it is a scanned document: Open the PDF, use the mouse to try to select a piece of text and copy it to Notepad. If normal text can be copied, it means that the file itself has a text layer; if it cannot be copied or it is all garbled, it can basically be judged to be a scanned copy or a picture-based PDF. This step determines whether you want to do OCR.
- Check the clarity of the original: Skewed, shadowed, and blurred photos will directly affect the OCR quality. If conditions permit, straighten the page first and scan it again, which saves time rather than correcting and identifying errors later.
- Determine the final use: Will you just read the translation, or will you need to revise it after the translation is completed? The former can be translated directly, while the latter needs to take the Word route, which will determine your first step.
- Planning file storage: The exported Word and translation will coexist with the original. It is recommended to create folders according to "Original, Recognized Draft, and Translation" to avoid mixing them together and not being able to tell which version is the new version.
- Confirm whether sensitive content is involved: Before uploading contracts, medical records, and internal materials to online tools, read the tool's privacy statement before deciding whether to upload them.
Steps to convert scanned PDF to editable Word in OmniDoc
- Download and install the OmniDoc desktop client (download.omnidoc.top), open it and import the scanned PDF to be processed.
- Perform OCR recognition on the file in the PDF editor to turn the text in the image into selectable text. After the identification is completed, randomly check two or three pages to confirm that the text is basically correct.
- Export the file to Word format in the PDF editor to obtain a .docx file. This Word is the basis for subsequent editing and translation.
- Open the exported Word and check whether the paragraphs, headings, and page breaks are roughly consistent with the original. If you find obvious typos or line breaks, you can modify them directly in Word before proceeding to the next step.
- Upload this Word file in OmniDoc for document translation. You can use the web version (omnidoc.top) or desktop client.
- Select the output method: select bilingual comparison when reading is required, or select translation only when translation is required. If it is a professional text, you can choose the corresponding stylistic style, such as academic, legal, medical, technical, business or literary, and pay attention to check whether the terminology is consistent.
- After the translation is completed, download the result and save it as a new file. Do not overwrite the original Word after recognition to facilitate comparison back.
- Open the translation in Word, read it from beginning to end, and then check the list in the next section one by one.
Check each item after completion
After you get the translation, do not send it to others or submit it directly. Both machine translation and OCR may make errors, and important content needs to be confirmed item by item against the original.
| Check items | How to see | What if there's a problem? |
|---|---|---|
| Numbers and dates | Compare it with the original one by one, focusing on the amount, number and date. | Go back to the original amendment and retranslate the paragraph |
| Proper nouns and terms | Is the name of the person, organization and product model consistent? | Replace the same with search, and write down the common terms to be used in subsequent modifications. |
| Form | Whether the rows and columns are complete and whether the cells are misplaced. | Adjust manually in Word, or go back to the original to make up for the missing |
| Formulas and symbols | Whether the superscripts and subscript, Greek letters and fractional lines are correct | Modify the original one by one, and it is recommended to rewrite the complex formula manually. |
| Number of pages and paragraphs | Whether the number of pages is roughly in line with the original, whether there are missing pages | Go back to step 2 to re-identify the missing page |
| Tone of translation | Whether it conforms to the type of text and whether it is blunt or omitted. | Re-select the style according to the style and rewrite partially. |
# Core comparison
There are three common ways to transfer scanned parts to Word translation, each of which is suitable for different situations.
| Mode | Suitable for what? | What should I pay attention to? |
|---|---|---|
| Upload scan PDF translation directly | As long as the translation, there are few steps | It is not convenient to revise the translation sentence by sentence. |
| Export Word after OCR and then translate | Need to edit, modify, reprocess | One more step of recognition, to check the recognition results. |
| Translation after manual word-for-word input | The original is very poor and the number of pages is very small. | Time-consuming and easy to miss words |
# frequently asked questions (FAQ)
1. What if the format is confused after scanning PDF and translating it into Word?
Most of them are caused by broken lines or columns during identification. First correct paragraphs and columns in Word, tables and formulas need to be manually repaired against the original, complex typesetting does not have to be complete at once.
2. Can I use the free online tool for scanning translation?
You can look at four points when choosing: file size and page limit, whether the result is watermarked, whether the privacy policy is clear, typesetting and whether the form can be retained. Don't just look at the word "free", try it with a short document before deciding whether to deal with formal materials.
3. My PDF can select text, do I still need OCR?
It's not usually necessary. PDF with existing text layer can be directly exported to Word or uploaded for translation. OCR is mainly used for image files. If some pages are found to be blank after export, these pages are identified separately.
4. Does OCR recognize the wrong word, must I change it before translation?
It is suggested to change. Recognition errors will be magnified by translation, for example, if the number "8" is recognized as "6", the translation will still be wrong. First correct obvious typos in Word, and then enter the translation, rework is less.
# Summary
Scan PDF into editable Word and then translate, the key is to identify, export, and then translate, and set aside time for verification at each step. There is no unified answer to how pdf documents are translated into word, depending on whether you want a direct translation or a manuscript that can continue to be revised.
