Adobe Reader cannot do such a thing.
If the file is just slightly larger than 2MB, you can compress it into a ZIP or similar compressed format. If it is much larger, you may need a professional tool that can compress a file into multiple junks.
You will need Adobe Acrobat for this purpose.Adobe Reader will not be able to help you
How do I do it in Adobe Acrobat Professional? I can use Acrobat Pro at school. The file is 12MB and I need it to be around 2MB. The people at GoDaddy aren't able to assist me with altering my .htmlaccess file and I have no idea how to do that! Thank you very much for the help! :-)
In Acrobat, open a PDF file.
-Choose Document > Reduce File Size.
-Select Acrobat 8.0 And Later for file compatibility, and click OK.
When you choose the compatibility level, be aware that the newer the version of Acrobat that you choose, the smaller the file. If you choose compatibility with Acrobat 9, however, you should be sure that your intended audience does indeed have version 9 installed.
Name the modified file. Click Save to complete the process.
It is always a good idea to save a file using a different name so that you don't overwrite an unmodified file.
Acrobat automatically optimizes your PDF file, a process that may take a minute or two. Any anomalies are displayed in the Conversion Warnings window. If necessary, click OK to close the window.
Minimize the Acrobat window. View the size of the reduced file. The file size is smaller.
You can repeat steps stated above using different compatibility settings to see how they affect file size. note that some settings might actually increase the file size.
PDF Optimizer offers more opportunities to control quality trade-offs.
Choose File > Close to close your file.
