What is the difference between semantic and overlay?

Semantic shows text differences. Overlay displays both files on top of each other visually.

Files are processed for comparison only and deleted from the server shortly after.

Can I sync scrolling between files?

Yes. Enable sync scroll to navigate pages together.

Does it work on mobile?

Yes. The interface is responsive and works on modern devices.

What does this PDF compare tool do?

It shows differences between two PDF versions so you can see which pages or regions changed before you approve the new file. It helps when a contract or policy comes back edited.

Upload original and revised files, then step through diffs in the preview. Check the cover and numbering so layout shifts are not mistaken for clause changes. Take notes outside the tool if you need a record.

Compare is not merge, and it is not a certified legal redline for every hidden change type. Files are deleted after the session. Do not upload copies your network forbids leaving the building.

When do you need to compare PDFs?

Reviewing a contract a lawyer sent back with edits.
Confirming a new manual only changed the safety page.
Spotting missing pages between a draft and the print file.
