About this tool
Two files with similar names and no certainty which one is current: "final_report.pdf" and "final_report_v2.pdf". Instead of reading both, compare them.
You get a match percentage and only the lines that changed, with a little context around them, the way version control does it. If both texts are identical, we say so and you skip the review.
How it works
- 01
Drop both PDFs.
- 02
Compare.
- 03
Switch between "only the changes" and the whole document.
Questions
What does the match percentage mean?
The share of lines that did not change. A quick guide: 98% is usually a minor correction; 40% is a rewritten document.
Does the order I drop them in matter?
Yes: the first is the earlier version, the second is the new one. You can swap them if you got it wrong.
