Compare two PDF files side by side to see what changed — useful for contracts, drafts, and revised reports.
Scroll and zoom both documents together, then generate a change report that highlights deletions in red and additions in green. Download that report as a PDF without uploading either file.
How to compare two PDFs
- Drop PDF 1 (older or baseline) and PDF 2 (newer) into PDFPeach.
- Review them side by side with linked scroll and zoom.
- Run the comparison to build the change report.
- Download the report PDF with red deletions and green additions.
Why compare PDFs with PDFPeach
Word-style track changes are not always available when both versions are PDFs. A local side-by-side view plus a downloadable report makes revisions obvious without sending contracts through a cloud diff service.
PDFPeach runs entirely in your browser — free, private, and practical for legal, ops, and editorial reviews.
When to compare PDFs
- Checking a redlined contract against the prior draft
- Verifying a vendor updated the right sections
- Spotting copy edits between report versions
- Confirming page adds or removals across revisions
Side-by-side view
Open both files, scroll and zoom together, and visually inspect layout differences before or after generating the report.
Change report
The report compares the text on each page, marks removals from PDF 1 in red and additions from PDF 2 in green, and downloads as a PDF you can archive or email.
Caveats
Scanned PDFs without selectable text show little or no text differences. Layout-only shifts may not appear as word diffs. Different page counts are supported — extra pages count as added or removed content in the report.
Frequently asked questions
What does the change report include?
Text differences with deletions in red and additions in green, downloadable as a PDF. Scans without selectable text will show little text change.
Can the PDFs have different page counts?
Yes. Extra pages are treated as added or removed content in the report.
Does compare work on image-only scans?
Visual side-by-side still helps, but the automated text report needs selectable text in the PDFs.
Are my files uploaded?
No. PDF comparison runs entirely in your browser on PDFPeach — free, with no account required.
