Frequently asked questions
What does the comparison check?
It compares the text content of both PDFs word by word. Formatting changes such as fonts or colors, and changes inside images, are not detected.
Can I compare scanned PDFs?
Scanned PDFs contain images, not text. Run both through OCR PDF first, then compare them.
Are my documents uploaded?
No. Both files are compared in your browser.
