PDF (Portable Document Format) is a very common type of file format we come across in our day to day digital life. Developed by Adobe in 1993, PDF is one such file format that is independent of software, hardware or operating system — they can be opened or accessed or edited from any device.
But there are times when you are needed to upload a document online, where there is a restriction on the size — for example; sometimes certain websites ask for the PDF file to be 500KB or less if we try to upload a document which is more than 500KB it won’t be uploaded.
That’s when we have to compress the PDF files.
Compressing a PDF is free, and you can do it via online PDF compression tools — no need to install any application on your computer or mobile phone.
In this article, we will list some of the best online PDF compression tools where you can compress PDF files in a jiff.
The operation is almost always the same on every one of these free compression tools — you upload the PDF file you need to compress, select the compression settings and done, then download the compressed PDF file.

What is compressing PDF files mean?
Compressing a PDF is to reduce the size of the file and so that we can send it by email or upload it to any website or storing it will take up less space. No information will be lost, but it will reduce the size of PDF files — like the PDF collection available on PDF drive.
Obviously, the quality level could drop if we do extreme compression. Although they are usually still manageable and normally, you will only see that slight loss of quality in the images and graphics you have but not in the text.
Advantages and disadvantages of PDF compression
There are many advantages of compressing a PDF using any of the PDF compression tools that we will tell you next.
- The main advantage is that it is easier to handle small files and not only handle them but also storing them.
- Carry it on a Pendrive or USB memory or mobile phone’s internal memory; it will be better if they occupy less space, and compressing a PDF will allow you to optimize space.
- You will also get a better transfer speed.
- Sometimes compression becomes a necessity for certain online portals as I have mentioned above.
- Compression is also useful when we want to send it as an attachment in an email.
The main drawback of using these online tools to compress PDF files is that of security. Since we upload the document to the website, the site admin will access the document and may use it or leak it, etc. So we do not recommend that you do not use these online PDF compression tools to compress your confidential files.
Most of them promise and indicate that the website deletes the files after a time, an hour, or a day, but even so, we recommend that you do not share “secret” files on these websites.
Compress PDF files directly from Word
One of the common and easy ways to compress a PDF is when we save the file from Word.
When saving it, you can choose to take up little space if you are going to do it from Word. In other words, you have a text document in Word that you want to save as a low-sized PDF. In that case, you can export it as such, and you will achieve a minimum size which is ideal for sending by email or for uploading to a web page.
Remember, don’t save it from the “Save as” option. Instead, follow these steps:
From the document, tap on file. Choose “Export” from the left options panel. Click on “Create a PDF / XPS document”
At the bottom, look for “Optimize For:” You can see two options: Standard (online publishing and print and Minimum size (publishing online). Choose the second option. And tap on “Publish.”
After tapping on “Publish,” the document will be saved with an optimal size making it easier to share, save on a device, etc.
