I want to edit text and delete some pictures and background in pdf. How can I do this without downloading any software?
With Acrobat Reader, you can select and copy/paste from the PDF to your Word document. Then create a new PDF, using either a paid or free PDF writer utility.
But in some cases, the format and layouts will be changed if you just copy and paste. Adobe reader can just view PDF but not edit. I will convert PDF to Word using AnyBizSoft when I wanna edit a PDF. It is fast and accurate. You can have a try. Here is the link. http://www.anypdftools.com/pdf-to-word.html#163 Sorry that I can't figured out another solution without downloading software.
If you look for paid / downloadable tools, there are also other OCR tools that can read pdf files directly. Google: http://www.google.nl/search?q=ocr+pdf+to+word
No Need of buying you'll be able to find a freeware by Googling, if can't PM me. I'll find one for you.
