Frequently asked questions

Paste two blocks of content and find differences instantly with our tool flagging every change for you

How does the "Compare" tool highlight changes?

It uses a side-by-side view with color-coded highlights—usually red for deletions and green for additions.

Can it detect changes in images or just text?

Our tool performs a pixel-by-pixel comparison, meaning it can flag if an image was moved, resized, or swapped.

Is this tool useful for legal contract reviews?

Absolutely. It is the fastest way to see exactly what an opposing party changed in a revised contract or NDA.

Can I export a "Difference Report"?

Yes, you can download a summary report that lists every change made between the two versions of the document.

What if the pages are in a different order?

Our smart comparison can identify when a paragraph has been moved to a different page rather than deleted.
