Use cases

Contract review cycles

Watermark contract PDF drafts with DRAFT or firm name — branded PDF documents for counsel without cloud exposure.

Invoice client portals

Watermark invoice PDF copies before upload to vendor portals — secure PDF sharing watermark deters unauthorized redistribution.

Board report distribution

Watermark reports PDF financial packets with CONFIDENTIAL before director review — confidential business PDF stays local.

Pre-share compliance

Watermark PDF before sharing externally — company document watermark satisfies policy without transmitting bytes.

Problems we solve

Cloud upload violates policy

Regulated firms cannot send PII to random servers. Zero-knowledge local processing watermarks business documents without transmission.

Unmarked external shares

Email attachments leak without status labels. Secure PDF sharing watermark makes draft vs final obvious to recipients.

Massive archive limits

Watermarking company PDF folders over 100MB exceeds free-tier browser memory — Premium handles enterprise-scale batches.

Trust & privacy

Zero-knowledge architecture

We never see your file bytes — watermark business PDF jobs run entirely in your browser Web Worker.

Text and logo options

Confidential business PDF labels or company logo — branded PDF documents with opacity and rotation control.

No retention policy needed

Because files never upload, there is nothing stored on our side — watermark PDF before sharing with confidence.
