The Invoice Watermark Generator draws a diagonal watermark — COPY, DRAFT, SAMPLE, CONFIDENTIAL or your own text — into every page of an invoice PDF, with colour, opacity and angle set, entirely in your browser.
A watermark is how a document says what it is not. COPY means it is not the original and should not be paid again. DRAFT means it is not final. SAMPLE means it is not real. CONFIDENTIAL means it should not be forwarded. On an invoice, every one of those prevents a specific and expensive mistake.
This adds a diagonal watermark across every page of an existing PDF invoice, or across an invoice you build here. Choose the text, the colour, the opacity and the angle; the watermark is drawn into the PDF itself rather than overlaid as an annotation, so it prints, survives being forwarded, and cannot be switched off in a PDF viewer.
Your PDF is opened and modified in your browser. It is never uploaded — which matters, because a PDF invoice is precisely the document you would not want to send to a watermarking service.
Not an annotation, so it prints and cannot be toggled off.
COPY, DRAFT, SAMPLE, DUPLICATE, CONFIDENTIAL or your own.
Readable underneath at around a quarter opacity.
However long the invoice.
The PDF is modified on your machine.
Any PDF, any number of pages.
COPY, DRAFT, SAMPLE, DUPLICATE, CONFIDENTIAL, or your own.
Colour, opacity and angle. Around 25% opacity stays readable underneath.
Every page carries it, drawn into the page itself.
It is drawn into the page content rather than added as an annotation, so it cannot be toggled off in a viewer. Someone determined with PDF editing software could remove it — a watermark communicates status, it is not security.
Between 15% and 35%. Lighter disappears on a poor printer; darker makes the figures underneath hard to read, which defeats the purpose on an invoice.
No. It is read and modified in your browser using a PDF library loaded on demand. Nothing about the document is sent anywhere.
Always a copy. Keep the unmarked original as your record and watermark what you send out, so the status is visible on the copy without altering the document of record.
