Preguntas frecuentes
How is this different from Compare PDFs?
Compare PDFs diffs exactly two files, once. This tool takes 3 or more versions and runs that exact same diff between every consecutive pair (v1→v2, v2→v3, ...), then lays the results out as a timeline so you can see how the document evolved step by step instead of only start-to-finish.
How do I control which version is which?
Add your files, then use the up/down arrows on each one to arrange them in chronological order, oldest first. The timeline compares each file only against the one immediately after it in that order.
Does this reimplement its own diffing logic?
No - each step uses the exact same page-by-page text extraction and line-diff engine as the standalone Compare PDFs tool, just run once per consecutive pair of versions.
What if two consecutive versions have no differences?
That step is shown as "no text changes" and its page-by-page detail is collapsed, so you can focus on the versions that actually changed something.
Is my document uploaded anywhere?
No. Every file is read and compared entirely in your browser - nothing is uploaded to a server.
