Important limitations of browser-based PDF processing.

Document fidelity

Browser conversions can differ from desktop software. OCR is not perfectly accurate, repair is best effort and large documents can exceed available browser memory.

Security-sensitive tools

Visual signatures do not automatically provide certificate-based identity verification. Cropping and whiteout are not secure redaction. Secure redaction intentionally rebuilds page appearance and can remove interactivity.

Standards and compliance

PDF/A compliance should not be inferred from metadata alone. Legal, archival or regulated use may require independent validation or specialized software.
