How to Edit PDF Files without Adobe Acrobat
 Looking for software to edit your PDF documents? This guide describes 
free alternatives to Adobe Acrobat that will help you edit and save PDF 
files.
Convert Word Documents in PDF! w/ the Free PDF Converter for PC.   

The
 PDF file format was originally created by Adobe in the early ’90s and 
there are now over 700+ million PDF documents on the Internet according 
to Google (search for filetype:pdf).
There are several reasons why
 the PDF file format is so popular for exchanging all sorts of documents
 including presentations, CAD Drawings, invoices and even legal forms.
- PDF files are generally more compact (smaller in size) than the source document and they preserve the original formatting.
 
- Unlike
 Word and other popular document formats, the content of a PDF file 
cannot be modified easily. You can also prevent other users from 
printing or copying text from PDF documents.
 
- You can open a PDF 
file on any computer or mobile device with free software like Adobe 
Acrobat Reader. Google Chrome can read PDFs without requiring plugins 
and it can create PDFs.
 
Edit PDF Files using Free Alternatives to Adobe Acrobat
While
 PDF Files are “read only” by default, there are ways by which you can 
edit certain elements* of a PDF document for free without requiring the 
source files or any of the commercial PDF editing tools like Adobe 
Acrobat.
We will primarily focus on tools that let you alter the 
actual contents of a PDF file>. If you are looking to manipulate the 
PDF file structure itself like rearranging pages or merging multiple 
PDFs into one, please refer to this detailed Adobe PDF Guide.
An Online PDF Editor for Basic Tasks
Sometimes
 you need to make minor changes to a PDF file. For instance, you may 
want to hide your personal phone number from a PDF file before uploading
 it online or may want to annotate a page with notes and freehand 
drawings.
You can perform such edits in a PDF easily with PDFEscape.com, an online PDF editor that is free and also lets you edit password-protected PDF documents in the browser.
With
 PDF Escape, you can hide* parts of a PDF file using the whiteout tool 
or add annotations with the help of custom shapes, arrows, text boxes 
and sticky notes. You can add hyperlinks to other PDF pages / web 
documents.
 [*] Hiding is different from redaction because here we 
aren’t changing the associated metadata of a PDF file but just hiding 
certain visible parts of a PDF file by pasting an opaque rectangle over 
that region so that the stuff beneath the rectangle stays invisible.
Change Metadata of PDF Files
If you would like to edit the meta-data associated* with a PDF document, check out Becy PDFMetaEdit.
 This is a free utility that can help you edit properties of a PDF 
document including the title, author name, creation data, keywords, etc.
The tool can also be used for removing PDF passwords as
 well as for encrypting PDF documents such that only users who know the 
password can read the contents of your PDF files. And since this PDF 
metadata cum bookmarks editor can be executed from the command line, you
 can use it to update information in multiple PDF files in a batch.
 
[*] If you planning to post your PDF files on the web, you should 
consider adding proper metadata to all the files as that will help 
improve the organic rankings of your PDF files in Google search results.
Edit the Text of a PDF File
If
 you want to edit the text in a PDF file but don’t have access to the 
source documents, your best bet is that you convert the PDF file into an
 editable Word document or an Excel spreadsheet depending on the 
contents of the PDF.
Then edit these converted PDFs in Microsoft 
Office (or Google Docs) and export the modified files back into PDF 
format using any PDF writer.
If your PDF document is mostly text, you may use the desktop version of Stanza
 to convert that PDF into a Word document. If the document includes 
images, charts, tables and other complex formatting, try the online PDF 
to Word converter from BCL Research or the one from NitroPDF – the former offers instant conversion while the latter service can take up to a day though its yields more accurate results.
Advanced PDF Editing (Images, text, etc.)
Now
 that you know the basic PDF editing tools, let’s look at another set of
 PDF editors that are also free but can help you do some more advanced 
editing like replacing images on a PDF file, adding signatures, removing
 blocks of text without breaking the flow of the document, etc.
First there’s PDF XChange,
 a free PDF viewer cum editor that you also may use for typing text 
directly on any PDF page. PDF XChange also supports image stamps so you 
may use the tool for signing PDF files or for inserting images anywhere on a PDF page.
Then you have Inkscape, a free vector drawing tool (like Adobe Illustrator) that can natively import and export PDF content.
With
 Inkscape, you can select any object on a PDF page (including text, 
graphics, tables, etc.) and move them to a different location or even 
remove them permanently from the PDF file. You can also annotate PDF 
files with Inkscape or draw freehand on a page using the built-in pencil
 tool.
The next tool in the category of advanced PDF editors is OpenOffice Draw with the PDFImport extension.
 OpenOffice Draw supports inline editing so you can easily fix typos in a
 PDF document or make formatting related changes like replacing color, 
increasing or decreasing the text size, replacing the default 
font-family, etc.
Like Inkscape, the OpenOffice toolbox also 
includes support for annotations, shapes, images, tables, charts, etc. 
but here you have more choices and the software also looks less complex.

The
 OpenOffice suite is a little bulky (they don’t provide a standalone 
installer for Draw) but if you have the bandwidth, OpenOffice is 
the best tool for manipulating PDF documents when you don’t have the budget for Adobe Acrobat.
