Часто задаваемые вопросы

Quick answers.

Is my document uploaded to a server?

No. The watermarking process happens entirely within your browser using JavaScript. Your original file and the watermarked version never leave your computer.

Can I customise the appearance of the watermark?

Yes. You can modify the text content, font size, rotation angle, and opacity levels to ensure the watermark is visible without obscuring the underlying content.

Will the PDF quality decrease?

No. This tool adds a vector or text layer on top of your existing pages rather than re-encoding the entire document as an image, preserving the original sharpness.

Does this work on password-protected PDFs?

No. You must remove the owner password or encryption from the PDF before you can apply a watermark to the document layers.
