Spot Every Change Between PDF Document Versions
Reviewing revised legal contracts, supplier agreements, or engineering specifications line-by-line is time-consuming and error-prone. Critical alterations—such as an adjusted payment date or an altered liability limit—can easily escape notice. Our free PDF Compare Tool automates document comparison, highlighting every word addition and deletion side-by-side.
Why Use In-Browser Document Diffing?
- Side-by-Side Visual Review: Easily scan changes with added terms highlighted in bright green and removed phrases struck out.
- Detailed Difference Metrics: Instantly check the overall document similarity percentage, added word count, and deleted text volume.
- Strict Client-Side Confidentiality: NDAs, M&A contracts, and legal affidavits contain sensitive proprietary information. EasyToolz processes both PDF files entirely in your browser memory without cloud servers or third-party tracking.
Frequently Asked Questions (FAQ)
Are my confidential contracts uploaded to a server?
No. Both PDF documents are parsed and compared locally in your browser memory using PDF.js. Your contracts never leave your computer.
What if the page count differs between the two PDFs?
Our diff engine compares the entire continuous text stream across all pages, correctly mapping changes even if paragraphs have shifted onto new pages.
Can I compare scanned documents?
This tool requires text layers. If your PDF is a photo scan, run it through our OCR PDF tool first to generate readable text.
Is there any fee or file size limit?
No. EasyToolz is completely free with unlimited comparisons and zero registration.
