Hello Radhika,

There's no need to worry.

The size of a PDF file can vary tremendously depending on the Adobe PDF settings used to create the file. For example, files created using the High Quality Print preset will be larger than files created using the Standard or Smallest File Size presets. Regardless of the preset used to create a file, you can often reduce the file size without having to regenerate the PDF file.

In this section, you'll use the Reduce File Size command to dramatically reduce or compress the size of a PDF file.

1. In Acrobat, open a PDF file.
2. Choose Document > Reduce File Size.
3. 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.

4. 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.

Best of luck.
