How to edit a PDF file

[Charles Keller]

Is there a PDF File Creator which you can edit after the PDF file is reated? I also cannot see a "save" option in the "PDFCreator 0.8" program or do I look at the wrong place?
Besides "PDFCreator 0.8" are there other PDF file Creators Programs on the Shareware market which I should look at?

This looks to me like a "General Computing" question, so off it goes.

AFAIK there's nothing that can change a PDF once created.
That's in fact one of the advertised strengths of the format, in that it allows verifiable content (once you send someone a PDF you know exactly what they got and they can't change it and claim that that's what you sent).

The app which should work is Adobe Acrobat 6. Yeah, the problem is it is very pricey )

I think Acrobat itself can also only create the files. Adobe designed the format to be read only so it can serve for certifiable transfer (once you send it you know what the other side has exactly).

My understanding is that PDF is just a compressed subset of PostScript. Sometimes it's encrypted. Editing one is basically as hard as editing the other: impossible. You could go PDF->PostScript->JPEG and do it like that I guess

If you have the unsigned PDF one than you can edit the file under Acrobat 6 Pro (limited capabilities, dont imagine edit like in Word). I just tried to crop, edit the text, and insert the comments. All works.
