Good to know
Local processing. Maximum 50 MB per file, 100 MB total, 20 files and 2,000 pages; splitting is capped at 100 pages. Encrypted or malformed PDFs are rejected. Edits can invalidate signatures. Page-copy operations may lose forms, outlines and document-level features. Metadata removal is not redaction or complete sanitization: annotations, attachments, page-level metadata and visible content may remain.
