If the document is in PDF format, it’s likely to be in its final format — ready to wow your audience. This is where high-quality graphics are used and where the final version of the text is rendered, ready to print or share with others to read or distribute. This could mean a large file size, especially if it’s a document heavy with images.
While you can modify a PDF, you will have to lower the quality to reduce the overall file size. If you want to know how to compress a PDF file, you can work around this problem by compressing the file instead of changing the image quality using a built-in or third-party app on Windows and Mac or using an online compression service.
How to Compress PDF File on Windows with PDF Compressor
There are no built-in methods to compress a PDF file on Windows 10, unless you want to add it to a zip file first. This means that you will need to use a third-party compression tool to compress the PDF file.
Although there are many tools, one of the best options is Free PDF Compressor. This free app has been around for several years, but it is still one of the easiest and fastest ways to compress a PDF file on Windows.
Download, install and launch Free PDF Compressor to get started. In the Free PDF Compressor window, click the button Browse next to the PDF file option to select your file. Provide the destination and file name of the zip file in the Output file box.

Using online PDF compression services
If you do not want to download additional applications to compress your PDF file, you can use several online PDF compression services instead. If you want to use an online service like this, you should only do so with non-sensitive documents.
Using these services involves uploading the file to a remote server, where the file can remain in place for a period of time. This poses a significant security risk for any documents that may contain personal data, and you should only use online compression services for files you are happy to share publicly.
There are various online PDF compression services, such as I Love PDF. Most services work in a similar way, by letting you upload the file, select the quality, and then download the zip file.
To use I Love PDF, press the button Select PDF Files Select the PDF files you want to compress. You can also drag and drop files directly into the website window for automatic upload.
Once the files have been uploaded, you can select the compression level from the left-hand menu. The higher the compression, the lower the quality of the output file (and vice versa). Locate Extreme Compression to the maximum pressure possible, or Recommended Compression For medium pressure but of reasonable quality, or Less Compression For minimal pressure but with much higher quality. click on the button PDF compression To start pressing as soon as you are ready.
Compressing PDF files will be completed on the remote server. click on the button Download compressed PDF file Download the zip file once you are done. The amount of compression (along with the amount of file size saved) will be displayed below.
If you want to save the file to cloud storage, or distribute it to others using the I Love PDF service, you can use the share icons to the right of the download button. This includes options to share on Google Drive or Dropbox, as well as to create a QR code or share link to share with others.
I Love PDF also offers the option to delete, allowing you to remove the file from its servers. To delete the file, press the . icon delete. While this will disable the link on the I Love PDF website, this does not guarantee that the file will be completely deleted from the website’s servers using this method.
As mentioned earlier, you should not use services like I Love PDF for sensitive documents. For any type of sensitive document that contains personal data, you should use an application option to compress the file instead, such as the Preview or Free PDF Compressor applications described above.
Compressing a PDF allows you to reduce the file size without reducing the quality too much (unless you want to). This makes it easy to share it online, via email, or other file-sharing services. You can also password protect your PDF files to keep the contents of sensitive documents safe from intruders.
If you are having difficulty opening a PDF file, you will need to install a good PDF reader such as Adobe Acrobat or Foxit Reader.
