Fill & Sign
Complete a form and sign it without printing anything. Type into fields, add today's date, and place a signature you draw with the mouse, type in a script font, or upload as an image — then flatten the result so it travels as a finished document.
Signed PDFs land in your Signed folder.
What you can do with it
Handy things people use Fill & Sign for
A few real-world jobs it makes quick — you'll find plenty more.
- Sign a rental or membership form and email it straight back.
- Fill in a form that has no interactive fields, by placing text on the page.
- Add a date and initials to a document you were sent as a scan.
- Sign something private without uploading it to a signing service.
What it does
Everything Fill & Sign handles
A focused set of jobs, each done well — and nothing that phones home.
Three ways to sign
Draw with the mouse or a trackpad, type your name in a script font, or upload a photo of a signature you already have.
Place text anywhere
Plenty of forms have no real fields at all. Click where you need text and type — no field required.
Flatten when you're done
The signature and the text become part of the page, so what you send is not a stack of editable annotations.
It never leaves your PC
The whole point. A signed form usually contains exactly the things you would least like sitting on someone else's server.
How it works
From file to finished in a few clicks
- 1
Drop the PDF in
With interactive fields or without — both work.
- 2
Fill and place your signature
Type into fields, click to add text where there are none, and place your signature and the date where they belong.
- 3
Flatten and save
The result is written as a new file with everything drawn into the page.
Under the hood
The engines, named plainly
The engines, named plainly.
- Stamping
- pdf-lib — draws into the page's content stream
- Page preview
- PDFium (WebAssembly build)
- Typed signatures
- Three script fonts, licensed under the SIL Open Font License
- Signature type
- Visual mark — not a certificate-based digital signature
- Platform
- Windows 10/11 (x64) — runs fully on your machine
Read that last row carefully. This places a picture of a signature onto a page, the same way signing a printout with a pen does. It carries no cryptographic proof of who signed or when, and it is not a PAdES-compliant eSignature. For most everyday forms that is exactly what is wanted; where a certificate-based signature is specifically required, this is not it.
