Sometimes we want to email a PDF file only to find out that the size of the file is too big to send. It can happen when you’re trying to send many different files, but can even happen if you’re trying to send one large PDF file.
If this happens, what are you supposed to do?
Fortunately, it’s actually easy to compress a PDF file for you to email or send to others. We’ve gathered popular methods from around the internet to be able to help the most people. Pick the best method that works for you!
Compressing a PDF means that you are reducing the file size of the document, so the file takes up less storage space.
The main reason to compress a PDF (or any file) is to reduce the size of the file to make it easier to send online.
There are two types of compressed PDF files:
This preserves the quality of the PDFs, since they can be “unzipped” after being received.
This truly compresses a PDF file, itself. The PDF is optimized and the file size is reduced, so you can send the PDF as is. Note: some quality loss may occur (especially image-heavy files), but modern PDF editors can balance compression while retaining a lot of quality.
There are multiple ways to compress and reduce the file size of a PDF. We’ve listed the most helpful methods that are available to Windows 10 users.
Attaching and sending PDFs via email is one of the most common reasons why people compress PDF files.
1. Right-click the PDF you want to compress.
2. Send to > Compressed (zipped) folder.
3. In your email client, attach the compressed file to your email.
4. Send the email.
The easiest, fastest, and most reliable way to compress a PDF is by using a PDF editor. We’ll be using PDF Pro because of it's simplicity and affordable price, but you can use the editor of your choice.

If you have more than one PDF that you want to compress, you can compress them in Google Drive!
1. Upload the PDFs you want to compress to Google Drive.
2. In Google Drive, select the PDFs with your mouse (press and hold [ctrl] on your keyboard to select multiple files).
3. Right-click > Download.
You now have a compressed (zipped) folder containing your compressed PDFs that you can email, send online, etc.
It’s possible to compress an encrypted or locked PDF even if you don’t know the password, however compressing a PDF will not bypass security settings, such as passwords. So you’d still need to unlock the PDF normally before being able to open or edit it.
Does compressing a PDF reduce quality?
Yes and no.
If you optimize a PDF by reducing the size of the file itself, then the quality will be reduced a bit. But if you “zip” your PDF in a compressed “zip” folder, then the PDF will be able to be extracted from the folder in the same size and quality — quality of the content will not be affected.
How do you make a PDF smaller?
The easiest way to make a PDF smaller is by using a PDF editor like PDF Pro, and optimizing the PDF to reduce the size of the file, while maintaining good quality.
In PDF Pro: File menu > Optimize > Optimize the document and reduce its size > Optimize
