Methods to Compare Two PDF Files

1. Manual Comparison

When it comes to comparing PDF files, the traditional manual method can still be effective. Here’s a step-by-step guide on how to compare two PDF files manually:

Look for differences in text, formatting, images, and any other elements that may vary.
Take note of the variations you find, either on paper or in a digital document.
