Why compress PDFs to 100kb

We all have PDFs that are larger than they really need to be. Whether it's a scanned document, a report with images, or a presentation you've saved as a PDF, these files can take up a lot of space without much good reason. This tends to cause problems when you need to share them: many email services and online platforms have upload limits, and an oversized PDF can slow down transfers or get rejected altogether. Keeping your PDF files small also helps if you're storing large numbers of documents, as the space adds up over time.

A 100KB target is a versatile size for compression, as it gives you enough room to keep images and formatting looking reasonable while still being small enough to send and store without issues. Zamzar's online PDF compressor makes the whole process quick and easy. You upload your PDF, and Zamzar will produce a compressed version for you to download in just a few moments. This works well for a range of documents, from scanned invoices and forms to short reports or portfolios with photos. It's also a useful option if you're regularly sending files to clients or colleagues and want to avoid the back-and-forth that comes with files that are too large to attach.
