How to Stamp APPROVED on a PDF: Watermarks as Document Status Markers

Status stamps solve a coordination problem that email threads handle badly. When five people hold copies of the same invoice, the question that wastes everyone's time is not what the document says but what has happened to it. A large APPROVED across the page answers that before anyone opens a thread to ask. The same applies to PAID on invoices, RECEIVED on deliveries, DRAFT on circulating proposals, and VOID on superseded versions. The stamp is metadata made visible, and visible metadata survives being forwarded in a way that a note in an email body does not.

Mechanically, a status stamp is a watermark, and PdfWill's watermark tool is how you apply one. Type the word you need, set the appearance, and it renders across every page of the document, entirely inside your browser with no upload. Applying it to all pages rather than only the first is usually correct for status marks, because pages get separated, printed individually and pasted into other documents. If a stamp genuinely belongs on one page only, split that page out, watermark it, and merge it back, the same three-step pattern used for single-page rotation.

The settings determine whether the result looks official or amateurish. Colour carries meaning, so red reads as urgent or negative and suits VOID or REJECTED, green or blue reads as positive and suits APPROVED or PAID, and grey suits neutral markers like DRAFT. Opacity is the setting people get wrong most often: somewhere around 25 to 40 percent is the sweet spot, because it stays clearly legible while leaving the text underneath readable. Angle matters less than people expect, though a diagonal of roughly 45 degrees signals a stamp, while horizontal text can be mistaken for part of the document.

Size and placement deserve a moment of thought. A stamp large enough to span most of the page width reads instantly at thumbnail size, which is exactly when you want it noticed, but it will overlap body text, and that is the trade-off you are accepting. If the document is a form or a table where every cell matters, a smaller stamp placed in a consistent corner is the better compromise. Whatever you choose, use the same word, colour and position every time; consistency is what turns a decoration into a signal your team reads without thinking.

Stamps and signatures do different jobs and work best together. The watermark answers what state the document is in; a signature answers who authorised that state. For an approval that needs both, apply the watermark first, then use the sign tool to place your signature image, your initials, or an uploaded approval graphic such as a department stamp or company logo, since the sign tool accepts any image you upload and lets you position it on the page. Finish with the protect tool if the approved version should not be casually edited, and keep the unstamped original as your working master.
