the ten-minute ritual
Stamp and sign freight documents without printing
Freight paperwork still runs on stamps and signatures: CMR consignment notes, PODs, delivery notes, invoices. The usual ritual is to print the PDF, stamp it, sign it, scan it, and email it back — ten minutes and a working printer for one impression of a rubber stamp.
This tool replaces that loop. Open the PDF, draw your signature or upload a photo of your company stamp, drag it into place, and download the stamped file — same document, same quality, no printer. PNG stamps keep their transparent background, so the stamp sits over the page like ink instead of a white sticker.
How it works
four boxes, in order
1Open your PDF
Drag it onto the page or choose a file. It stays on your device.
2Add your mark
Draw a signature with your mouse or finger, or upload a stamp or signature image (PNG or JPEG — PNG keeps transparency).
3Place it
Drag the mark into position, resize it, and copy it to every page if you need the same stamp throughout.
4Download
The stamped PDF is saved next to your original as “yourfile-stamped.pdf” — the original is never modified.

Frequently asked questions
Is this PDF stamping tool really free?
Yes. Opening a PDF, drawing a signature or uploading a stamp, placing it, and downloading the stamped document is free, with no limits on files, marks, or pages. Optional convenience features for people who stamp paperwork every day — saving your signature and stamps for one-click reuse — are paid, but the core tool has no caps.
Is my document uploaded anywhere?
No. Everything happens in your browser: pdf.js renders the pages on your own device and pdf-lib writes your signature or stamp into the file locally. The document is never sent to our servers — we never see it, and there is nothing for us to store or leak.
Is the signature legally binding?
This tool places a visual image of your signature or stamp on the document — a simple electronic signature. It is not a qualified electronic signature (QES) under eIDAS, and we make no claims about legal validity. Whether a simple electronic signature is sufficient depends on the document and the parties involved — you are responsible for that judgement. This is not legal advice.
Does it work for scanned PDFs?
Yes. Scanned or image-only PDFs — a photographed CMR, a scanned delivery note — render and stamp like any other PDF. The stamp is placed visually on the page, so no text layer is needed.
Can I reuse my stamp or signature?
With Quietmill Pro (€9/month) you can save signatures and stamps and place them again with one click — useful if you stamp the same documents every day. Saved marks live in your browser's local storage, not on our servers.
Can I open password-protected PDFs?
No. Password-protected and encrypted PDFs are not supported — remove the password first, then stamp the document.
Quietmill provides formatting tools. This tool places the signature or stamp image you provide onto the PDF you choose; it does not verify identity, certify documents, or create qualified electronic signatures, and nothing on this page is legal advice. You are responsible for whether a simple electronic signature is appropriate for your documents.
