What CompareDesk does
A tool for everyday document work.
Compare Word documents
Two versions of a DOCX file are compared word by word. You receive the result as a Word file with tracked changes.
Compare PDF
PDF documents are also compared at text level. The result is output as a clear redline PDF.
Compare Excel
Excel workbooks (XLSX) are compared cell by cell. The result is delivered as an Excel file in which changed, inserted and deleted cells are marked per sheet.
Contracts revision by revision
Inserted text appears blue, deleted text struck through in red, moves in green. Every change remains individually traceable.
Two stages, one clear result
First the structure, then the word.
CompareDesk® first recognises which paragraphs match and where they are. Only in the differing sections is a word-by-word comparison performed. This keeps the comparison clear and reliable even for large, rearranged documents.
- Unchanged sections remain unmarked.
- Changed paragraphs are shown word-precisely.
- Moves are recognised as such.

What you should know about CompareDesk.
Which file formats can I compare?
Word files (DOCX, DOC), RTF, TXT, PDF and Excel (XLSX). You receive the result as a Word file with tracked changes or as a redline PDF; for an Excel comparison the result is delivered as an Excel file.
Are my documents uploaded?
No. The comparison runs entirely on your own computer. Your documents do not leave your workstation.
How does the free plan work?
You can run ten full comparisons in total for free and without signing up. After that, a licence unlocks unlimited use.
Is there a macOS version?
CompareDesk is currently available for Windows. A macOS version is in preparation.
What are the system requirements?
CompareDesk runs on Windows. The Word file with tracked changes is created without additional software. For the colour redline PDF from a Word comparison, Microsoft Word or, alternatively, LibreOffice is required; comparing two PDFs does not need this.
Is the formatting preserved?
CompareDesk preserves the layout of the original: font, size, bold, indentation, tables, headers and footers as well as numbering. Background watermarks and letterhead are detected and kept out of the compared text, so they are not mistakenly pulled into the result.
