Frequently Asked Questions

How much does it cost?

You can use the solution for free with limits on the size of your documents (number of pages and file size).

A Premium offer is available to compare documents with no size limit.

How do I compare documents?

To compare two documents, first select them on your computer. Move them to the "old document" and "new document" areas, then click on "Compare".

When the comparison is complete, DeltaDoc will display the two versions side by side and highlight the differences in the documents.

Deleted text is highlighted in red (in the document on the left).
The added text is highlighted in green (in the document on the right).

Text that has been replaced is considered to be a combination of a deletion and an addition.

Something is highlighted but hasn't been changed.

Inevitably, sometimes DeltaDoc is not able to determine if there is really a change between the two versions (because of the encoding of the document or the quality of the scan).

In these cases, we highlight them to make sure that no changes are missed. Contact us to improve the tools for your specific documents.

What is synchronized scrolling?

DeltaDoc takes into account holes/additions of content to align documents with each other. This is why the scrolling of the two versions may have different speeds. It is synchronized scrolling that optimizes your viewing experience.

My document is fully highlighted (or not at all)

This usually means that your document has been scanned, and that it is in fact only an image.

With the Premium Package, you can activate the Optical Character Recognition (OCR) option before clicking on "Compare".

My document is too long or too voluminous
