如何查看PDF的比较

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 边界

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.
