The "File Too Large" Nightmare

We've all seen it: you try to send an important email or upload an application form, and you get the dreaded error message: "File size exceeds the limit." Email providers often cap attachments at 25MB, and government or job portals can be even stricter, sometimes limiting uploads to just 2MB or 5MB.

Why Are PDFs So Big?

PDFs can become bloated for several reasons:

  • High-Resolution Images: Scanned documents or photos are the usual suspects.
  • Embedded Fonts: Storing every character style takes up space.
  • Hidden Metadata: Information you don't see but that adds weight.

How Compression Works

PDF compression works by optimizing these elements. It might slightly lower the resolution of images (often imperceptibly to the human eye), remove redundant data, and simplify internal structures. The goal is to get the smallest file size with the best possible quality.
