Is It Safe to Convert Confidential Documents Online?

Learn how to assess privacy risks before converting confidential documents, including uploads, metadata, browser processing and file retention.

File handling

Overview

Confidential files require more care than ordinary images or public documents. Before converting one, understand whether the file will be uploaded, what metadata it contains and how the conversion provider handles data.

Identify the sensitivity

Examples of sensitive documents can include contracts, financial information, business records, unpublished work and personal records.

Prefer minimal data transfer

If the required conversion can be completed locally in a trusted browser environment, unnecessary transfer of the source file can be avoided.

Inspect metadata

Removing visible information does not necessarily remove document metadata.

Consider your device too

Malicious browser extensions, compromised devices or shared computers can create privacy risks independently of the converter.

Use local/offline software for extremely sensitive material

For highly confidential or regulated documents, a fully offline workflow may be more appropriate depending on organizational requirements. Format Convertly does not claim suitability for every regulated workflow.
