Remove PDF Annotations

Batch-remove comments, highlights, shapes and links — page content stays untouched. For scripts and metadata too, use Sanitize.

Auto-detect PDF interactive form (AcroForm) fields, fill text fields, checkboxes, or radio buttons, flatten, and download — runs entirely in your browser.

Local Processing (Offline Capable)

Cover text by keyword with white boxes (masking only — the text layer remains). For true removal use Redact or PII Redaction.

Apply PAdES digital signatures to PDFs via server-side pyHanko, with RFC 3161 trusted timestamping and PAdES LTA readiness check (signature, signature timestamp, DSS evidence, document timestamp).

Cloud Processing (Encrypted)

Extract text in your browser, then run server-side PII detection to find names, addresses and organisations, returning structured JSON.
