How to convert pdf to txt easily?

My kindle3 will arrive tomorrow, and I have plenty of PDF files that I want to read on it.

I would like to convert them to txt so I can adjust the font size.

Is there any convenient way to do that?

PS: if there isn't, I shall write one by myself.

Calibre can convert PDF to txt, or better yet, the .mobi reflowable/resizable format supported by the Kindle. It's great open source software for ebook management, which you might want to have installed anyway, once you own a Kindle.

AbiWord is an open source word processor that can import PDF and save it as .txt (or .html or a variety of other Word Processor formats).

As you probably know, Amazon has its own conversion service.

I can think of quite a few additional options, but they would depend on your operating system.

OK, here is an alternative hacky way to do it, without installing anything on your computer (and just for fun).

If you have a gmail address, send the pdfs to your gmail address, then (using the gmail web interface) do a 'view as html'. (I do this sometimes to extract the images).

"pdftotext" (from Xpdf).
