The DRAFT stamp generator draws a rubber-stamp style DRAFT mark onto an invoice PDF — every page or just the first — with a date and note beneath it, or produces the stamp on its own as a transparent PNG or SVG, entirely in your browser.
A DRAFT watermark is the only safe way to send an invoice for approval. Without it, a draft attached to an email can be paid, entered into an accounts system or filed as a tax document — and then there are two versions of the same invoice with the same number.
This produces the stamp two ways. Drop an existing PDF invoice and the stamp is drawn onto every page — or just the first — at the angle, colour and opacity you set, with an optional date and note underneath such as a payment reference or the reason. Or build the invoice here and the stamp prints across the preview, the PDF and the HTML download.
It also produces the stamp on its own as a transparent PNG or an SVG, in a rubber-stamp style with a double border, for use in any other document. Everything happens in your browser: the PDF is opened and stamped on your machine and is never uploaded.
Drawn into the page, on every page or the first.
A reference or reason printed beneath the stamp.
Double border, angle and opacity, previewed live.
Transparent PNG or SVG for any other document.
The PDF is stamped on your machine.
Or skip this and use the stamp image on its own.
When the invoice is not yet final, and anything worth recording beside it.
Colour, angle, size and opacity, previewed live.
Every page, or just the first.
The stamped PDF, or the stamp as PNG or SVG.
When the invoice is not yet final and a copy of the document is going to somebody else — so the status is visible on the page itself rather than only in your system.
It produces a new, stamped PDF and leaves your file untouched. Keep the unstamped original as your record.
It is drawn into the page content rather than added as an annotation, so it cannot be switched off in a viewer. A stamp communicates status; it is not tamper protection.
No. The PDF is opened and stamped in your browser with a PDF library loaded on demand. Nothing about the document is sent anywhere.
