Way to convert

Word itself can open a PDF and resave it as a Word document. Have you tried that?

But one thing worth mentioning, if you scan a document and save it as a PDF file, only an OCR will be able to partly recover the text out of the image.

And if you are looking for a library, have a look at https://docs.aspose.com/display/pdfjava/Convert+PDF+to+other+Formats

Not if the document has password protection

I found MS Word as a good converter. So try it and you'll see if it does what you want.

I reccomend Adobe Acrobat DC. It does the job very well.

I may do the job the best, however, you pay for it.

Thanks to all.
Is there no free good converter/site to change PDF format into Word document?
Actually details (of PDF file) are becoming a mess when using Word to open it.

Adobe Acrobat DC is chargeable. Any other option?

The paid for option I use is Solid PDF to Word
https://www.soliddocuments.com/
Which is (aside from Adobe) the only package I've found which gives you WYSIWYG conversion.
But agree there isn't a good free alternative which maintains layout.

Can you help to change attached file to a Word file?

If you provide the password I can convert it for you.

Sorry, is there a way to remove any password of PDF file?
