Compare PDFs
View two PDFs side by side and see what text changed.
About Compare PDFs
Drop two versions of a contract, a paper or a report and see exactly what changed. Pages line up side by side, and added or removed text is highlighted so you do not have to read both.
- Works best on text PDFs; scans need OCR PDF first.
- Use the text-only view for long documents.
- Page counts can differ; the tool aligns by content.
