How to compare PDF files
Add both PDFs
Drop the original and the revised PDF. You can also compare a PDF against a Word document.
Matchcheck reads the text
The text of each document is extracted in your browser and split into paragraphs.
Review every change
Changed paragraphs are shown side by side, with edited words highlighted, like 30 days becoming 14 days.
What Matchcheck does
Built for contracts
Spot edits to dates, amounts, notice periods and clauses between two drafts.
PDF against Word
Check that a signed PDF matches the final Word draft.
Word-level highlights
Small edits stand out, even in long paragraphs.
Confidential documents stay private
Nothing is uploaded, so it's suitable for legal, medical and financial documents.
Questions and answers
Does it compare images and layout?
No. Matchcheck compares the text. Changes to images, fonts, colours and page layout aren't detected.
Why does my PDF show no text?
Scanned PDFs are pictures of pages, with no text inside. They need text recognition (OCR) first, which Matchcheck doesn't do yet.
Can I compare a PDF with a Word document?
Yes. Drop a PDF on one side and a .docx file on the other. Both are turned into paragraphs and compared the same way.
Are password-protected PDFs supported?
Not yet. Remove the password first, then compare.
