Part 1. Why Lower MB of PDF?
It’s important to lower the MB of a PDF when uploading documents to online forms, attaching files to emails, or sharing materials with colleagues or clients. I often run into this issue when I try to upload PDFs on certain websites. These platforms usually require the file size to be under 10 MB, and it becomes frustrating because the moment my PDF exceeds the limit, the system rejects it. This example clearly shows how problematic large file sizes can be. There are also other reasons why you should keep PDF files smaller, such as:
- Easy Sharing: You can easily and quickly share your compressed PDF files via email, messaging apps, and online platforms.
- Faster Uploads: You can quickly upload your smaller PDFs and share them with your clients, coworkers, and so on.
- Improve Performance: Compressed PDFs are easier to open on slow internet connections and older devices. You can also use your mobile devices to upload them.
