Part 4: Other ways to compress a PDF file for Email

Besides using a PDF compressing application or online service, you can also use some other solutions to compress the size of your PDF file so that you can successfully send it through email. Here are other two ways to make your PDF file size smaller.

1. Use Google Drive

If you are using Gmail to send your email with the PDF file, then you can actually upload a PDF file that is bigger than its attached limitation. But when you do, your attachment will not be attached as an independent file. Instead, it will be a link linked to your Google Drive. And your attachment will not be attached in the email but uploaded to your personal Google Drive and shared to the person who is receiving your email.

This method is very simple for Gmail and Google Drive users. Instead of directly sending the attachment, you're actually sharing a file in your Google drive to the person who's receiving your email. So there is basically no limitation for your file to be shared in email. However, it will certainly cause some trouble if the person who's receiving your email does not use Google Drive.

2. Zip Your File

Another way for you too compress a file to attach in an email is to zip it before you upload the attachment. This is very simple when you have a zip tool installed on your computer like 7-zip.

But if you zip the file and send it through email, the attachment will no longer be a PDF file, but an archive file. This means that the person who's receiving your email will not be able to directly open the PDF document after downloading the attachment. A zip/unzip application is required for him or her to extract the original PDF file from your attachment.

Besides, using a zip file does not promise a very strong compressing result. If your attachment it's very large in size, it is very likely that the file would still be too big for email even after zipping it.
