How to Compress a PDF, Reduce the File Size, and Make It Smaller

Unfortunately, there is a downside to the fact that the PDF packages everything into the one file. If a document has lots of images and design features, then the file size can be very large. This can take up space on your device and also cause problems or delays when sending through email or uploading to a website or portal. Luckily, learning how to compress a PDF is simple. You Can also use pdf editor to reduce PDF size Without losing quality.

PDFs have a huge advantage over other file types in that they can be viewed in exactly the same way on almost any device. The reason for this is that all design elements, such as custom fonts and image elements are contained within the file itself. In short, the recipient of a document doesn’t need to have the program used to create the PDF to read it.

Other file types need the program’s file system that they were created in to render any design elements properly. As an example, think about opening a PowerPoint document in OpenOffice Impress. If you used a font in PowerPoint that Impress doesn’t have, then it will use a replacement font. Not such a big deal you might say, but with more complex documents, perfectly formatted tables may misalign and/or images won’t display properly. This is why PDFs are so commonly used to distribute important agreements, forms or widely distributed newsletters, brochures and infographics.

Why compress PDF files?

Before looking at how to decrease the size of a PDF, it’s good to understand why it is needed. As mentioned above, PDFs can incorporate a lot of elements and consequently become very large. Having many of those files can cause your computer to lag and work inefficiently. Storing them in the cloud is a solution, but there are storage limits there as well.

Even if you do have enough disk space to deal with bulky files, transferring them can present difficulties. Attaching a large file to an email may be time-consuming, and if it is too large, you won’t be able to send it at all. The file size limit for attachments has increased over the years, but Outlook still only allows 20 MB and Gmail 25 MB. There are often similar size limits when uploading to portals for work or study. Compressing large PDFs is simply a necessity in this case.
