Tips for Reducing the Size of Your PDFs

There are several factors in how PDFs end up having a large file. Aside from images, embedded fonts and content streams (texts, comments, vector graphics, and so on) can also contribute to large PDF file sizes. Let's review each option, so you know what to do in each situation.

Large Image Size

Removing excessive resolution reduces the size of the PDF file. Most online PDF compressors do the same thing—but when you do it manually, you get to choose which images get compressed and to what extent.

Heavily Embedded Fonts

If fonts are your main issue, you can remove the least used ones (Traditional Chinese, Japanese, and Korean). If you do this, the text in these languages will be displayed in a font that is available on the system where the file is being viewed.

Hidden Objects and User Data

Are content streams to blame for your PDF's large size? Additional content in your file can be removed using the 'Discard Objects' and 'Discard User Data' panels. JavaScript actions, document tags, alternate images, and bookmarks are among the Objects. Comments, forms, file attachments, and private data from other applications are examples of user data.

However, you could exercise extreme caution when deleting this data because it may have an impact on the accessibility of your PDF.


It's easier to share a compressed and optimized PDF file online (for example, via email). It also means that uploading and downloading times are reduced. It's good that there are several methods for reducing the size of a PDF, and the majority of them are quick and simple.

But, among the methods discussed above, one was exceptional due to its user-friendly interface, countless advanced features, cloud storage services, and multi-platform PDF solution for ease of use. So, if you're having problems with large-sized PDF files, don't be afraid to use PDFelement – the ultimate All-in-One PDF Solution.
