How to compare two PDFs
Updated: · Agah Emre SÖZEN
Finding which clause changed in a contract that came back from the other side by reading line by line is tiring and risky; a single figure is easy to miss. The easy way to compare two PDFs is a tool that puts the text of both documents side by side, sentence by sentence.

Steps to compare two documents
- 1Open quillo.tr/compare-pdf.
- 2Choose the old document in the first box and the new one in the second. They can be PDF, Word or text.
- 3Press Compare.
- 4Added sentences appear in green and removed ones in red. In a changed sentence only the changed words are marked.
- 5Download the differences as a text report if you like.
What does the comparison look at?
The tool compares the text of the documents: sentences, figures, dates. Each difference shows the page it is on. Fonts, margins, images and signatures are not compared.
A scanned PDF has no text layer, so there is nothing to compare. Make it searchable at quillo.tr/ocr-pdf first, then compare.
Making sense of the differences
If you wonder what the differences mean, add both documents to the app and ask Ai: it summarises in plain language which change favours whom. For a legal decision, still consult a professional.
