In Detail: How to Compress PDF File Size to 1 MBs and Lower.

There are a variety of ways to compress PDF files for email and file storage, depending on the system and tools you have at your disposal. You should also keep in mind that the more you compress a file, the more the quality may be reduced.

It can be useful to know how to compress PDF file size if you’re looking to send or view large documents online. Often, PDFs are too large to send over email or even save onto your desktop, so reducing the file size can save a lot of inconvenience.

One of the most popular options is compressing via Adobe Acrobat, which can be accessed on most systems. If you have an Internet connection, all you need to do is drag and drop a PDF file into the converter, select the quality and click Compress.


If you’re not online, you can use Acrobat Pro’s PDF size converter tool while you have the application open. All you need to do is:

1. Open your file in Adobe Acrobat.

2. Select the Tools centre and click Optimise PDF.


3. Choose a file to compress.

4. Click Reduce File Size in the top menu bar.

5. Pick the file version compatibility.

6. Rename and save your compressed PDF.

Depending on the original PDF size, your new document size should be close to 1 MB or below. If it isn’t, you can use the PDF size converter tool a second time to try and compress further. You can use the Reduce File Size command in Acrobat to choose the exact level of compression you want.
