Privacy & security

Less file transfer, fewer places for sensitive documents to travel.

Last updated: 9 September 2026

Local by design

Document transformations run inside your browser. PDF and image batch operations use web workers where supported, so processing is separated from the page interface. There is no server-side document queue, account database or public file-storage service in this release.

File handling safeguards

The tools validate supported types and impose size, page, image-dimension and workbook limits. Imported HTML is sanitized. Office archives are checked before expansion. Spreadsheet formulas are parsed with a formula engine rather than evaluated as JavaScript. Macro execution and external document data connections are not supported.

What this does not guarantee

Browsers, third-party libraries, operating systems and extensions can have vulnerabilities. Local processing is not a claim of perfect security or regulatory certification. Do not use an untrusted device for sensitive work. A successful conversion does not certify the accuracy or legal suitability of its output.

Redaction and signatures

An ordinary shape or crop is not secure redaction. The separate redaction workflow creates new image-only pages after removing marked areas. A drawn signature is a visual mark, not a certificate-backed digital signature. Read the relevant guide before sharing sensitive output.

Reporting a concern

Use the contact page to report an issue with reproducible steps and non-sensitive sample data. Do not send real personal information, passwords, identity documents or confidential business records.
