Fix: "The file appears to be corrupt"
The error 'The file appears to be corrupt' means the .docx file's internal ZIP structure is incomplete or broken — a byte is missing, the file was cut off during download or transfer, or the container was written incorrectly. This is a file integrity problem, not a conversion problem, so any converter will fail on the same file.

About .docx to PDF conversion
Can OpenAny convert a corrupt .docx to PDF anyway?
Sometimes, yes. OpenAny uses LibreOffice under the hood, which has partial tolerance for minor ZIP corruption and can occasionally extract enough content to produce a PDF. Upload the file and try — if the damage is light, you will get a usable PDF. If the corruption is severe, the conversion will fail and you will need to repair the file first.
How do I repair the corrupt .docx before converting it?
Open Microsoft Word and use File > Open, then click the dropdown arrow on the Open button and choose 'Open and Repair' — Word will attempt to reconstruct the file from whatever it can read. If you do not have Word, upload the file to Google Docs, which also has its own repair logic. Once you have a working file, bring it back to OpenAny to convert to PDF.
Why did my .docx become corrupt in the first place?
The most common causes are an interrupted download (the file was not fully transferred), an email attachment that was truncated by a size limit, a failed save when Word crashed mid-write, or a storage device with bad sectors. Check the file size against what the sender reports — a smaller-than-expected file almost always means it was cut off in transit.
