How to convert and modify graduation thesis PDF to Word

Key points of this article

First drag and select a piece of text in the PDF: if it can be selected, export it directly. If it cannot be selected, it means it is a scanned document and needs to be OCRed first.
The conversion only involves moving the content back to Word. The modified title style, table of contents, and page numbers still need to be rechecked according to the school template.
Formulas, charts and references are prone to errors after conversion, so check them one by one against the original PDF.
Keep the original finalized PDF before modification. The new file is named with the date or version number, and you can roll back the changes if they are messed up.

Many people search for "convert graduation thesis pdf to word", and what they want to solve is actually a very specific problem: after the defense, the instructor made suggestions for revisions, or needed to add a section of content, but they only had the final PDF in hand and could not find the Word source file used for the original writing. The direct way at this time is to transfer the PDF back to Word and modify it paragraph by paragraph in Word. This is not exactly the same as ordinary PDF to Word conversion, because the paper has already been formatted, and the troublesome thing after conversion is often not to move the text, but to keep the corresponding relationship between titles, figures, and references in the modified document.

This article is written for undergraduates and graduate students who need to revise their final papers, as well as those who help organize the materials of the papers. After reading, you can judge whether your PDF is suitable for direct export, know what to do before and after the conversion, and have an itemized checklist to avoid finding that the formula is misplaced and the drawing number is out of order.

# how to transfer the graduation thesis PDF back to the modifiable Word? Conclusion in a word

When you go back to Word, there are usually only two things to judge: whether you can select the text in the PDF, and whether you want to change the local text or the whole structure. If the text can be selected, it can be exported directly; if it is not selected, do OCR recognition first and then export it. When the range of modification is large, it still takes time to sort out the layout after conversion.

Your situation.	Recommended practice	Reason
PDF can select the text and change only a few sentences	Export directly to Word with PDF editor and modify it in copy	The text layer is complete and there are fewer errors after exporting.
PDF text is not selected (scanned or photographic version)	First do OCR recognition, check the recognition results, and then export to Word	The scanned document does not have a text layer, and you can only get pictures when exporting it directly.
To change the structure or format of the chapter	Reapply the title style after export and rearrange according to the school template	The transformation retains the content, and the structure needs to be straightened out by itself.
Change only individual data or formulas	After exporting, make partial modifications to the original PDF. The formula shall be subject to the original PDF.	Formula conversion is easy to deform, and the risk of local modification is low.
After modification, you need to continue editing on the web page.	After exporting the Word, open it in the UniDoc Web Page Editor (app.unidoc.top)	The web editor supports Word-compatible editing for subsequent modifications.

Before you start: Confirm these points first

Confirm which version is the final version. The same paper often has multiple PDFs, such as the review version, the defense version, and the school submission version. Select the base version before conversion, otherwise the modified content may not match the submitted version.
Confirm whether the PDF has a text layer. Open the PDF and drag to select a section of text. Text can be selected and copied, indicating that the text layer is complete; text cannot be selected or garbled characters are copied, usually in the form of scans or image-based PDFs.
Prepare the school’s format requirements. The regulations of font, font size, line spacing, headers and footers, table of contents and page numbers determine the extent to which re-typesetting is required after conversion. It saves time to get school templates in advance rather than guessing afterward.
Compile the instructor’s comments. If the modification comments are written in PDF comments, first summarize the comments into a list, and then modify them one by one according to the text to avoid missing changes.
Create an independent working folder. The original PDF, exported Word, and revised draft are saved separately and named with date or version number for easy comparison later.

Steps to convert graduation thesis pdf to word and modify it in OmniDoc

Open the PDF editor. After installing the OmniDoc desktop client, enter the PDF editor and select the final PDF to open. If you haven’t installed it yet, you can download it from download.omnidoc.top. The client supports Windows, macOS and Linux.
Do OCR on the scanned document first. If the first step of dragging and selecting text fails, perform OCR on the scanned PDF to turn the text on the page into a recognizable and selectable text layer.
Check the recognition results. After OCR, check several paragraphs of text, titles and tables page by page, and pay attention to whether numbers, letters and symbols are correct, such as "1" and "l", "0" and "O". The recognition results require manual verification and cannot be directly regarded as finalized.
Export to Word. Choose to export to Word format in the editor and pay attention to the saving location. Add a mark such as "modified version" to the file name and do not overwrite the original PDF.
Save a separate copy. Open the exported file in Word and save immediately as a new file. All subsequent modifications are made in the copy, and the exported file is retained as a comparison.
Organize the title hierarchy. Set the chapter and section titles to the corresponding title styles so that the table of contents can be automatically generated based on the titles. After conversion, the title is often just plain text in bold and needs to be confirmed one by one.
Modify content. Only change the paragraphs that need to be changed, and write down the page numbers and chapters for easy comparison later. When encountering complex formulas or charts, first find the corresponding position in the original PDF, and then compare and modify it.
Check the layout according to the school template. Check the page margins, font size, headers, footers and page numbers against the school’s requirements. If you ultimately need to submit a PDF, do the entire review again after saving as PDF in Word.

Check each item after completion

Check item	What do you think?	What if there's a problem?
Text integrity	Check the beginning and end paragraphs of each chapter against the original PDF to see if there are any missing sentences or repetitive paragraphs	The missing part is copied and added from the original PDF, and the duplicate segment is deleted.
Title and catalogue	Check whether the chapter level is consistent with the original text in the navigation pane of Word	Reapply the title style, and then update the catalogue
Formula	Compare symbols, superscripts and numbers one by one	Based on the original PDF, re-enter the key formula in Word if necessary
Chart and figure number	Whether the picture is complete, whether the caption number corresponds to the body citation	If the picture is missing, add it from the original PDF screenshot and correct the caption number.
References and citations	Is the number of items and the numbering order consistent with the body reference?	Uniformly adjust according to the format prescribed by the school, don't just change a few of them.
Page number and header	Turn to the preface, text, references, etc., to see if the page numbers are continuous.	Set up sections in Word and adjust the page number format separately
