Compare PDF gives you a quick side-by-side summary of two PDF files: page count and file size. It's a useful first check for confirming whether two versions of a document differ structurally at all, before you open both and read through the content yourself.
Step-by-step
- Upload File A — the original document.
- Upload File B — the revised document.
- Compare to see the page count and file size for each, side by side.
What this doesn't do yet
This tool does not currently extract or diff the actual text content of the two documents — it's a structural summary, not a line-by-line comparison. If you need to verify exactly what text changed between two versions, review both documents directly for now.
