Before you start

Ensure your document does not contain restricted custom fonts or extremely complex third-party formatting objects that may cause server-side conversion errors on other systems.

Solution 1Recommended

Save the Document as a Standard PDF Locally

Bypass the recipient's automated conversion issue by generating a standard PDF on your own computer and sending the finalized PDF file instead.

Instead of relying on the journal's system to convert the Word document, generating a standard PDF on your computer ensures the formatting remains intact and prevents third-party conversion failures.

Open your research paper in Microsoft Word 2021, click on the 'File' tab in the top left corner, and select 'Save As'.

4
Save and Submit

Click 'Save' to generate the file, then send this finalized PDF directly to the journal for testing and submission.

Frequently Asked Questions

Why does a Word document convert fine on my PC but fail on the journal's system?

The journal's conversion system may lack specific fonts used in your document, run an older version of the software, or struggle to process complex formatting features unique to Word 2021. Generating the PDF locally avoids these server-side limitations.

Does saving as 'Standard (publishing online and printing)' change my document layout?

No, this setting embeds the necessary fonts and ensures the PDF retains its exact layout and high resolution. It creates a slightly larger file size compared to 'Minimum size' but is ideal for professional printing and online publishing.

What should I do if the journal strictly requires a Word document upload?

If the journal strictly requires a .docx file and their system still fails to convert it, try simplifying the document by clearing complex formatting, embedding fonts via File > Options > Save > 'Embed fonts in the file', and re-uploading.
