Compare two PDFs
Someone sends back a contract “with a few changes”? PDFmoji compares both versions, sets aside mere layout changes and flags what matters: an amount, a date, an added “not”.

Why PDFmoji
Actually free
3 documents a month without paying or giving a credit card, and no ads at all.
Your files never leave
Everything runs in your browser: your PDF is not uploaded to any server.
Built for phones
Open the PDF you got by email, make the change, download. It works on computers too.
One tool for everything
Edit text, sign, fill in, merge, compress: no need to go through five websites.
Frequently asked questions
Does it work with scans?
It needs readable text: make scans editable first with the OCR tool.
Are the documents uploaded?
No, the comparison runs in your browser. Only if you ask for the Assistant’s analysis are the changed passages (not the whole documents) sent to it.
How long can the documents be?
Up to several dozen pages; beyond that, compare the parts you care about.
Is it really free?
Yes. With a free account you download 3 documents a month and make 10 Assistant requests, with no credit card and no ads. PDFmoji Pro (€5.99 a month, cancel anytime) removes these limits.
