Plenty of everyday documents just need your signature at the bottom: an internal approval, an acknowledgement, a form being returned to someone who knows you. Draw your signature with a mouse or finger — or type your name and let the page render it in a script face — choose the page and the corner, and this tool places it into the PDF, on your device.
What this is — and what it is not
Please read this first, because the distinction matters. This tool places a visual image of a signature onto a page. It is not a cryptographic digital signature: it carries no certificate, no identity verification, no tamper-evident seal, and no audit trail. A signed copy made here proves nothing by itself about who placed the signature or whether the document changed afterwards, and it may not satisfy formal or legal signing requirements — contracts, regulated filings, notarised documents and anything where the other side requires a verified e-signature. Where the law or the counterparty requires one, use a proper e-signature service built for that purpose.
Where it is fine
Plenty of real paperwork sits below that bar, and for those jobs an image signature is exactly what people already accept: internal approvals and sign-offs inside an organisation, informal acknowledgements (“received”, “seen”), drafts being circulated for comment, school and club forms, and documents where a wet-ink or verified signature will follow later anyway. Judge by what is at stake and by what the person receiving the file expects — if in doubt, ask them before you send, not after.
How placement works
Your drawing is captured from the pad as a PNG image, or your typed name is rendered onto the pad in an italic script face — either way the page holds one signature picture, drawn once and kept while you work, so you can re-run the tool with a different position without signing again. On the PDF, the image is placed 170 points wide (about 6 cm — a natural signature size) with its height scaled to the drawing's own proportions, on the first or last page as you choose, at one of six positions. Bottom right is the conventional signature spot; bottom centre suits centred forms; centre of the page turns the signature into more of a stamp. The choices are deliberately coarse — six honest positions rather than fiddly pixel dragging — and the original file is never modified, so a misplaced signature costs nothing: adjust and sign a fresh copy.
Private by design
Like every CalcViso file tool, this one runs entirely in your browser. The file you choose is read by this page, processed on your device, and offered back as a download — it is never uploaded to a server, never stored, and never seen by anyone else. Close the tab and it is gone from memory.
Worked example
Press the sample button: the page builds a 2-page sample PDF and, so the demo completes end to end, fills the signature pad with a typed “Sample Signature” in script. Keep the defaults — last page, bottom right — and press Sign PDF. Open signed.pdf and turn to page 2: the blue script signature sits in the bottom-right corner, exactly where a signature belongs. Clear the pad and draw your own name to see the difference a hand-drawn signature makes.
How to use this tool
- Drop your PDF onto the box (or create the sample).
- Make your signature: draw it on the pad with mouse, pen or finger — or type your name and press Use typed signature.
- Choose the page: last page for most documents, first page for covers and single-page forms signed at the top.
- Choose the position — bottom right is the conventional spot.
- Press Sign PDF, download signed.pdf, and open it to check the placement before you send it anywhere.
Getting a signature that looks like yours
Drawing with a mouse feels nothing like a pen, and a first attempt often looks like someone else's name. Three things help: sign bigger and faster than feels natural (slow strokes wobble), use a touchscreen or stylus if you have one — a finger on a phone or tablet tracks handwriting far better than a mouse — and use Clear freely: everyone, including people signing on paper, has a few false starts. If drawing defeats you entirely, the typed signature is the respectable fallback: it is legible, consistent, and honest about being typed. Either way, preview the signed page before sending — placement surprises (a signature floating over a table, or covering printed text) are visible at a glance and cost one re-run to fix.
