I have received a lot of PDF documents that I wish to convert to text formats such as docx/doc/odt.

I know there are some online tools that will do it for you, but some content may be sensitive with people's names and addresses and I'm not sure I can trust these websites.

Are there software that will convert a PDF to odt?

Things I know and tried:

1. Asked a friend to open PDF in Microsoft Word: Their license expired last month, so it doesn't let you save the file!

2. Tried to do the same on my LibreWriter: It doesn't support that format.

3. Tried to open in LibreDraw: untenable as I want to type more things in the document.

P.S: I use Linux, but reckon solutions for platforms would be fine.
