PDF files are incredibly useful in our daily lives, from work to education. They make it easy to manage and share documents across various platforms. Often, we scan documents using our phones, but the resulting PDF files can sometimes be low resolution, making them blurry and hard to read. If you’ve ever struggled with a scanned PDF that’s just too small and unclear, you’ll be glad to know that increasing the size and resolution of your PDF scan right from your phone is easier than you might think. This article will guide you through simple online methods to enlarge your PDF scan files, ensuring clarity and readability.
