Compare PDF Files

Upload two PDF versions and see added or removed selectable text grouped by page. This MVP is built for text changes, not pixel-perfect visual redlines.

For scans, forms, signatures, images, and layout changes, use OCR or manual visual review.

Maximum 1 GB per file. Best when text can be selected in the PDF viewer.

What this PDF comparison checks

Convertr extracts selectable text from each PDF with local Poppler tooling, normalizes page lines, and compares the line changes by page. It is useful for contracts, policies, drafts, reports, and other text-heavy PDFs.

MVP boundary

This version does not claim Acrobat-style visual redlining. It may miss layout-only changes, moved images, font changes, annotations, signatures, and scanned-page differences.
