PDF Compare
Comparing two PDF files manually can be frustrating. Whether you are a developer, QA engineer, writer, legal professional, or student, spotting tiny differences between documents is time-consuming and error-prone.

That’s exactly why I built and launched a PDF Compare tool on DiffGuru.com - a simple, fast, and privacy-first way to compare two PDF files online.

What is Diff Guru PDF Compare?

Diff Guru PDF Compare is a free online tool that allows you to:

  • Upload two PDF files
  • Instantly compare them
  • Highlight added, removed, and modified content
  • View clean, visual differences in seconds
  • No sign-up. No watermark. No tracking.

Why I Created This Tool

As a developer working frequently with:

  • API documentation
  • Project proposals
  • Legal PDFs
  • Client requirement documents

I needed a quick and reliable way to detect changes between versions. Most available tools were either:

  • Paid
  • Heavy desktop software
  • Slow
  • Or collected user data

So I built Diff Guru with 3 core principles:

  1. Speed
  2. Privacy-first
  3. Zero friction

Privacy Comes First

Your files:

  • Are processed securely
  • Are not stored
  • Are not logged
  • Are never shared

This makes Diff Guru safe even for confidential business documents.
