You could copy the page image (one at a time), paste it into Paint, then save as a JPG or BMP. You could edit it in Paint as a picture file, but then you would still need additional software if you wanted to change it back to a PDF.
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
I want to edit text and delete some pictures and background in PDF. How can I do this without downloading any software?
Additional software to what? You don't tell us what you have already, so "additional" is quite hard to qualify in this instance.
The nice, free way to do this would be to use openoffice 3 with the PDF import extension - for minor alterations like you're describing it works nicely, and saves to PDF as well.
Of course, whether you have openoffice 3 or not already will qualify as to whether you need additional software... if you're trying to do this with just acrobat reader though, the answer is no - it's not possible without additional software.
Don't think so. Last time I checked, photoshop could import PDF files but then just treated them as images, so you couldn't edit any individual components or text on them - and certainly couldn't natively save them back to PDF format.
It may have changed now, but I doubt it - photoshop is an image editing program and not really designed for this sort of use!
Look my dear :
if u convert this form into (JPEG ,BMB ,,,,,,,,)u can process it easily then u can convert it back to (PDF) form
I think at all that Adobe Acrobat slolves this problem
and I didn't Understand why u dont want to install any program??
