Is Add PDF Watermark safe and private for confidential files?

Yes. Add PDF Watermark uses Hybrid Local & Zero-Retention Ephemeral Cloud Processing. Client-side operations never leave your browser, and any server-assisted tasks are processed in ephemeral memory and permanently purged the moment your response finishes.

Does ProIT add watermarks or require software installation?

No. Add PDF Watermark runs entirely in your web browser on Windows, Mac, Linux, iOS, and Android, and never stamps watermarks onto your exported documents or images.

What are the file size and quota limits for Add PDF Watermark?

Standard free usage supports generous daily operations up to 10MB per upload with zero sign-up required. Upgrading to ProIT Pro or Business unlocks up to 100MB+ file sizes, bulk batch ZIP processing, and headless API key access.

Can I automate Add PDF Watermark via REST API or batch mode?

Yes! You can use the built-in Batch ZIP panel on this page to process multiple files at once, or generate an X-API-Key in your account dashboard to call /api/v1/tools/pdf-watermark/execute programmatically.
