About Add Watermark
Watermarking protects documents and communicates status — a draft, confidential, or branded file is easy to recognize at a glance. ILikePdf Add Watermark places text or image watermarks with full control over opacity, rotation, size, and position, applied to all pages or a selected range. The preview updates instantly as you adjust settings. Since watermarking runs in the browser, your original file is never uploaded, making it safe for legal documents and client deliverables.
