These are useful because these can reduce file size and save disk space and maybe you got some eBook on some interesting topic and you want to share that with your friends but can’t due to large file size of it. Sometimes your emails get in junk/spam folders due to attachments having large file size because usually some odd programs are attached with emails and to protect you, your email providers (i.e. Gmail, Yahoo or Hotmail) usually move such emails to junk/spam folders.
I think now you know why you should reduce file size of your PDF files if you want to share them with your friends.

Both are easy to use. If you have file with size less than 5MB then you can compress it using online tool but if you have large file size then I recommend you to download software. Play with options to get required file size.
