About Compare PDF
SindhTools does not upload files through this browser-side tool interface.
The output is a PDF report showing corresponding pages side by side. Extractable text is also checked when available; scanned pages may need OCR for text-level comparison.
Frequently asked questions
Are my files uploaded?
This tool interface is designed for local browser processing; no file-upload endpoint is used by this page.
Will every PDF work?
Encrypted, damaged, or unusually complex PDFs may fail to render. Scanned pages can still be viewed side by side, but OCR is needed for reliable text-level comparison.
