How to Compare PDFs Without Adobe Acrobat (Free)

Compare PDF document versions to find changes without Adobe Acrobat. Free browser-based diff tool.

Adobe Acrobat Pro has a document comparison feature, but at £17.99/month it is expensive for occasional use. FixMyPDF compares PDFs free.

Quick Steps

Go to fixmypdf.in/tools/compare-pdf. Upload both PDF versions. Compare. Review highlighted differences.

Privacy

Both PDFs are processed entirely in your browser. Neither file is uploaded to a server — important when comparing confidential contract versions or legal documents.

For Text Changes

The comparison is most effective for text changes. Formatting-only changes (font size, bold, colour) may not be highlighted depending on how they are represented in the PDF.
